Re: OutOfMemory Error in Catalina
Hi, I tried to increase the heap size to 1200 MB in catalina.sh file (JAVA_OPTS=-Xms64m -Xmx1200m), It didn't work. I was suggested one more way is to increase the server's maximum file descriptor limit. But I don't know where to increase this limit. Apart from that, is there any other way / utility to find out the root cause of OOM in catalina.out log file.

Re: OutOfMemory Error in Catalina
I bet your going down the wrong path for debugging, from the FAQ: -- You have too many threads running. Some OS's have a limit to the number of threads which may be executed by a single process. (Which is what the JVM is.) Refer to your OS docs for more information on how to raise this threshold. -Tim Abhijeet Selukar wrote: Hi, I tried to increase the heap size to 1200 MB in catalina.sh file (JAVA_OPTS=-Xms64m -Xmx1200m), It didn't work.

RE: OutOfMemory Error in Catalina
Howdy, I tried to increase the heap size to 1200 MB in catalina.sh file (JAVA_OPTS=-Xms64m -Xmx1200m), It didn't work. I was suggested one more It didn't work in what way? Did the JVM actually allocate 1200MB and then die with an OutOfMemoryError, or did it never allocate that much (e.g. because they're not that much physical memory). way is to increase the server's maximum file descriptor limit. But I don't know where to increase this limit. Then find out how, e.g. by reading your server's docs. It's usually ulimit on unix systems. Apart from that, is there any other way / utility to find out the root cause of OOM in catalina.out log file. Yes, it's a called a Profiler, preferably one that will give you heap snapshot deltas like OptimizeIt. But if your problem is at the OS level such as by having too few file descriptors, a profiler won't help you. Also know that a profiler requires much more memory be allocated to the JVM to support JVMPI overhead.

RE: OutOfmemory Error!
When App1 reports an OutOfMemoryError, does it means that the error is due to App1 ? or that error may be due to another application running the same VM? or the same TomCat? It is the VM. Is there any good way to make those two apps run independantly? Run two different tomcat instances (two different VMs). If you still want them both on the same port, put apache in front of it. ciao Filip -Original Message- From: Arcadius A.

RE: OutOfMemory Error
To answer your first question, I'm assuming you only have so much memory, so if you keep allocating memory, you'll eventually run out and then you'll have problems. As long as the JVM can reclaim memory, you should be alright. For your second question, it should look something like this: JAVA -Xms128m -Xmx256m Where -Xmx256m is your maximum heap size. It gave you that error because the default is 80 megs (which I'm having trouble with), so setting the minimum above 80 megs gives you the error message. http://java.sun.com/j2se/1.4/docs/tooldocs/windows/java.html For the windows standard and non-standard options (such as -Xms and -Xmx). Hope that clears it up for you. -Original Message- From: Patrick Codere [mailto:[EMAIL PROTECTED]] Sent: Thursday, August 15, 2002 1:10 PM To: 'Tomcat Users List' Subject: OutOfMemory Error Hi, outofmemory problem crashes my Standalone Tomcat Server(NT 4, Tomcat 4.03). large images on the site.

RE: OutOfMemory Error
Hi!!
If you are using UNIX.
Tune the memory settings in Tomcat as appropriate for your application.
To do this, edit /usr/local/jakarta-tomcat/bin/tomcat.sh and locate the
following line (approximately line 121):
$JAVACMD
OMCAT_OPTS -Dtomcat.home=${TOMCAT_HOME} -Xms100663296 -Xmx134217728
org.apache.tomcat.startup.Tomcat $@
Xms is the initial value, Xmx is the maximum value. Multiply 1048576 by the
total memory in MB to determine the appropriate number. For example, the
setting above has an initial value of 96 MB and a maximum value of 128 MB.

Hi Everybody !
I am geting this OutOfMemory Error for a couple of days now with no
stack trace.
Any idea what is wrong with TOMCAT ?
Is that anythiing to do with Low memory available ??
thanks

RE: OutOfMemory Error
Chances are you either: 1. Are using a very small stack (using -Xmx with a small number) 2. You are putting items into sessions that you aren't removing and your sessions aren't expiring fast enough to keep your system in memory 3. You have a servlet with a class or static variable that is some form of a list or map and you keep adding to it I have Tomcat installed on a server at a client location. Its been up for 30 days this time, 45 at the longest, and the memory has stayed pretty constant (creeping up and then back down with usage) Randy -Original Message- From: Shailendra T Kontham [mailto:[EMAIL PROTECTED]] Sent: Tuesday, June 19, 2001 4:20 PM To: [EMAIL PROTECTED] Subject: OutOfMemory Error Hi Everybody !
