If you can block that IP at a firewall before they get to your box that would be better. Failing that block the IP with iptables (or the equivalent on your platform) on the server.

Jasper compiler version, how to configure
In my development environment using JDK 1.5, the jsp compilation is fine. But after deploy to JBoss 4.0.5(w/ tomcat 5.5), the JSP compiler complains templates such as List I started JBoss using jdk 1.5, configured in run.sh (JAVA_HOME). It seems that the JSP compiler is not using the java version 1.5. How to configure the JSP compiler java version, using the same version JDK 1.5 that starts Tomcat? Thanks for help. Dave

SSL will actually make it slightly worse since Tomcat has to work harder to decrypt and encrypt the traffic. Filtering by IP is a good solution here, but if this is your first publicly exposed website be prepared: This happens all the time, and the client IP's will be wildly different...you can't possibly filter them all. You might consider a good IPS between you and the Internet at large. One example of a good free solution is Untangle. You can buy support as well if it makes you more comfortable.

Re: Tomcat JVM not releasing deleted files (lsof show delete inodes taking up disk space)
It's actually a vendor supplied application. I filed a bug/support request and they returned with a patch. I guess I was wondering if there were any jvm startup options I may have over looked that may help with this sort of issues. But it definitely seems to be a coding issue.

Can you share the code that actually does this? The javadoc for File.createTempFile states: To arrange for a file created by this method to be deleted automatically, use the deleteOnExit() method. If your engineers followed this advice, this may be your problem: the JVM is waiting until JVM shutdown to actually delete the files. Even if the code does an explicit File.delete(), the JVM is probably still hanging onto a reference to the file's directory entry in order to delete it on exit. That seems like a plausible explanation for why the files are marked as deleted in lsof, but are still being kept alive by the JVM. The solution here would be to simply not use File.deleteOnExit; instead, use File.delete explicitly. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkjlEpIACgkQ9CaO5/Lv0PBo0wCfRhUitB/6/pxDQiGtbdo0Ctwk qj4AnjuQwMY3yduWoAN5/InlbZnX1CW6 =i6Uc -END PGP SIGNATURE- - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Rainer Jung-3 wrote: but if the backend is stuck or too slow, this will not help and instead also trash the frontend. So perhaps.. upgrading from older JKs the default changed from 10 connections to 250. With a lot of workers (for instance, 40) the total number of maximum threads went from 400 to 1. I will have to fix this and check what happens. Yes, if the notion of worker is an IIS worker and not an isapi plugin worker. A plugin worker in the sense of a worker configuration item in workers.properties is 1:1 with a connection pool, and a connection pool doesn't create threads. It will grow at most as the lower of thread number and configured pool size. For iis workers see Mladen's response. Rainer Jung-3 wrote: You should measure how many connections you need during peak hours without performance problems, and then add some percentage depending on your growth rate etc. Finally you need to make sure, that your web server itself uses at least as many threads, as you configured as the pool size. This has been measured already. Same as above, when the problem were too few connections, too many seemed not to be a problem. :-) I would suggest to add your above sentence right after We recommend adjusting this value for IIS and the Sun Web Server at http://tomcat.apache.org/connectors-doc/generic_howto/timeouts.html and maybe also in http://tomcat.apache.org/connectors-doc/reference/workers.html (And maybe *strongly* recommend it ) Done.

It seems we are dying with the big default. :-) I have read somewhere that the number of threads is not likely to cause these problems on modern multiple cpu with multiple cores servers. I wonder if there is some kind of formula to know what total should not be exceeded in this particular case, of if the good old document by Mladen Turk is still valid fixing this number to 2000 (http://people.apache.org/~mturk/docs/article/ftwai.html) I do think so, although I didn't actually test recently.

Make that function *synchronized* !
Practically speaking, the synchronization status of this method

chance of this method returning an uninitialized instance of

Basic Tribes Questions
Hi, I am currently trying to use Tribes as the clustering layer on our server.
My startup code looks like this.
if(_tribesChannel == null)
{ // nothing to do if already running
try
{
_tribesChannel = new GroupChannel();
// must be done before start:
_tribesChannel.getMembershipService().getProperties().put(mcastPort,
String.valueOf(_mainPort));
_tribesChannel.getMembershipService().getProperties().put(mcastAddress,
_multicastIPAddr);
if(_ancillaryPort 0)
{
_tribesChannel.getMembershipService().getProperties().put(tcpListenPort,
String.valueOf(_ancillaryPort));
// hack alert: Default Tribes instantiation (Tomcat 6.0.16)
does not read value for tcpListenPort from properties.
// Therefore, set it directly
ChannelReceiver receiver =
_tribesChannel.getChannelReceiver();
if(receiver.getPort() != _ancillaryPort)
{
if(receiver instanceof ReceiverBase)
{
((ReceiverBase)receiver).setPort(_ancillaryPort);
}
}
}
_tribesChannel.addMembershipListener(_tribesMembershipListener);
_tribesChannel.addChannelListener(_tribesChannelListener);
_tribesChannel.start(CHANNEL_COMPONENTS);
}
catch(ChannelException ex)
{
try { _tribesChannel.stop(CHANNEL_COMPONENTS); }
catch(Throwable t) { /*gulp*/}
_tribesChannel = null;
throw new RuntimeException(ex); // todo, exception handling?
}
}
My Question is that when I start Server #1, then Server #2, then unplug Server
#2 network cable, Server #1 gets the DISAPPEARED message but Server #2 just
keeps logging the message below. As I write this it's at attempt #120. How do
I get this to notify on Server #2 that Server #1 has DISAPPEARED or can I set
the number of attempts to a maximum number before notifying?
Also is there any other documentation for tribes, other than the limited docs
on the apache site?

not sure what you are trying to do in the code below. if you wanna set
the port, then simply do it.
the membership will pick it up automatically

the message you are getting is cause the membership tries to recover.
you can limit this, by doing
setRecoveryEnabled(true|false);
setRecoveryCounter(nr-of-times-to-try-recover)
also, you haven't added in the TCP failure detector, which adds one more
layer of protection
see it in this default configuration
http://tomcat.apache.org/tomcat-6.0-doc/cluster-howto.html
you should still get the member disappeared error (eventually after the
timeout), if you can supply a simple test case, I can try it out over here.

Please let us have more infromation. Upon startup, it is typical of Tomcat to be very CPU-intensive for a while (length of the time is of course dependent on the CPU power available and application workload placed on the server). Other than that, the JVM running Tomcat will be largely idle, unless it is serving requests (with the exception of running the JVM to a memory exhaustion state, in which case the JVM can pretty much sit in a loop running garbage collection). So, clarifying questions; - are you referring to the 100% CPU usage right after startup (could take 10 seconds; could take a couple of minutes, depending on details) - is your Tomcat JVM running at its allocated heap limit - are there requests being served while the CPU is fully utilized - are you seeing this on a Tomcat with none of your own applications installed, or on a Tomcat having your applications deployed Depending on your OS platform, you might be able to look at CPU usage in individual threads within the JVM, and combine this knowledge with a thread dump from the Tomcat JVM instance, in order to see which are the busy threads (GC thread, worker thread, something else), and also to see at least a momentary stack dump of the busy thread (in other words, you might be able to see what code is running in the busy thread). You could also enable GC logging, to see whether there is excess garbage collection activity within the JVM (which would indicate either a memory leak or a too small JVM heap allocation). My first two claims would be: - it is caused by your application code (or libraries brought in with your application code) - it could be that your application code (or libraries...) is running against the JVM memory limit, making it run garbage collection in an endless loop (and if you let it stay that way long enough, it'll crash with an OutOfMemoryError) but I could just as well be wrong. It could also be some code in Tomcat getting stuck in an endless loop. It's just that bugs seem to be less common in Tomcat than in the typical webapps I see. -- ..Juha - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

yes pls follow leon's advice and compare your thread dumps so you can determine TC thread activity and coordinate that to the webapp's resource activity I would look at minHeap, maxHeap and stack parameters from %JAVA_OPTS% a 2004 post http://forums.sun.com/thread.jspa?messageID=10055131 says it best The default stack size is 256K on UNIX and on 32-bit Windows operating systems. To set Stack size java -XX:NewSize=128m -XX:MaxNewSize=128m -XX:SurvivorRatio=8 -Xms512m -Xmx512m 1. Setting the New generation heap size -XX:NewSize Use this option to set the New generation Java heap size. Set this value to a multiple of 1024 that is greater than 1MB. As a general rule, set -XX:NewSize to be one-fourth the size of the maximum heap size. Increase the value of this option for larger numbers of short-lived objects. Be sure to increase the New generation as you increase the number of processors. Memory allocation can be parallel, but garbage collection is not parallel. 2. Setting the maximum New generation heap size -XX:MaxNewSize Use this option to set the maximum New generation Java heap size. Set this value to a multiple of 1024 that is greater than 1MB. 3. Setting New heap size ratios -XX:SurvivorRatio The New generation area is divided into three sub-areas: Eden, and two survivor spaces that are equal in size. Use the -XX:SurvivorRatio=X option to configure the ratio of the Eden/survivor space size. Try setting this value to 8, and then monitor your garbage collection. 4. Setting minimum heap size -Xms Use this option to set the minimum size of the memory allocation pool. Set this value to a multiple of 1024 that is greater than 1MB. As a general rule, set minimum heap size (-Xms) equal to the maximum heap size (-Xmx) to minimize garbage collections. 5. Setting maximum heap size -Xmx Use this option to set the maximum Java heap size. Set this value to a multiple of 1024 that is greater than 1MB. pay attention to MaxHeap, MinHeap, StackSize and set your GC's to mark and sweep for discarded blocks HTH Martin Gainty __ Disclaimer and confidentiality note Everything in this e-mail and any attachments relates to the official business of Sender.

Re: useSendFile=true skips compression
Shaun Senecal [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Could someone explain to me why the NIO Connector will ignore the compression settings for large files if useSendFile is enabled (it is by default)? It seems to me that if compression is enabled you would specifically want to use it when sendFile is enabled, but that might just be because I don't really understand what sendFile means/does :) In normal mode, Tomcat reads the file into its own memory buffer, optionally compresses it, and then writes it out again to the socket. In sendFile mode, Tomcat tells the O/S to transfer the contents of the file directly to the socket (bypassing reading it in to Tomcat memory). On a modern O/S, this allows the O/S to transfer data using kernel memory only, instead of copying the kernel memory to program memory first (which has a significant cost on high-volume servers). It looks like my solution is to simply disable this option, but I was curious about why this is the case. I am trying to deploy a large GWT app, and I want to ensure that my massive JavaScript files get compressed before being sent to the client. - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
tomcat service restart
hi my problem is not common i have used tomcat 5.0.30 and java jdk 1.4.1.01 some time when application runs ,its not sure but tomcat service is stopped and we have to restart this. i am using struts 1.2 and hibernate 2 for my apps i could not justify this thing! i feel some like 1.i have generated dynamic form elements ,so some time ending close tag comes before opening tag!this may be reason? 2.tomcat 5 compatible with java 5? or another else?
