Hi, Thanks for your email Do you have enough RAM + swap space to support that large a heap, along with the other memory requirements of the Tomcat process and all other processes on the system? If not, you may well be getting hit by the Linux OOM-killer, which leaves few traces. Yes we do, we have 6GB total memory However Tomcat fails quite often, no trace information can be found in logs, neither my app logs nor tomcat logs. What about a core file, or a JVM crash file? No core files neither jvm crash files :( Best regards

Hi, We have enabled the GC logs on our production and our tomcat server crashed too!! Apparently, GC logs takes high CPU and eventually, tomcat server crashes due to high CPU utilization of GC logs. Remove them, your problem will be solved. What I believe is, enabling GC logs are not suggestible for long run. They are for observation the system and for short duration only.

Is there a kind of rule for jvm-tomcat/os memory proportions needed? There is no rule, but there was an earlier thread on this list with the message I quote below, which provides an idea of how many distinct instances of Tomcat one /can/ run in one machine with 32 GB of RAM. Divide by 164 to figure out how much memory one Tomcat /might/ need. You may want to read the whole thread in the list archives there is probably some information for you there.

Details differ a lot; the env was Tomcat 4.something, running on Solaris. However the symptoms did match: the Tomcat process just disappeared. What did help in our case was to wrap the startup in another layer of scripts which did redirect all the standard file descriptors to/from specified files (or /dev/null in case of standard input), and additionally start tomcat under nohup (protected from session hangup signal). What we suppose did happen: - admin started the tomcat (on a shell session) - the shell session was forgotten open, and the corresponding TCP connection later timed out at firewall - at some point some piece of code attempted to write to System.out or System.err, or read from System.in - this activity caused the machine TCP layer to notice that the TCP connection was not valid any longer, and so the shell from which Tomcat was started (and the Tomcat process, too) did get a hangup signal, causing both the shell and Tomcat to just stop and exit We could never positively prove the above, but that would suit the symptoms, and also the above would be something for which our cure would be effective. -- ..Juha - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

RE: Tomcat unexpectedly shuts down
Anthill is a third party app intended to store and execute Ant scripts. I mention it only because it's fairly well-known and maybe someone has seen similar problems before. Either way, the only thing running in this tomcat instance is 3 copies of Anthill. -Original Message- From: Propes, Barry L [GCG-NAOT] [mailto:[EMAIL PROTECTED] Sent: Thursday, January 11, 2007 6:26 PM To: Tomcat Users List Subject: RE: Tomcat unexpectedly shuts down isn't Anthill just a third party app to do war and ant builds?

Re: Tomcat unexpectedly shuts down
Hi Steve, Is there anything that flood your server with requests or trigger an infinite loop within the application ? I have similar experiences in 2 scenarios 1. A tomcat died every morning, Then we foundout that its flooded by requests at a certain time and there is a flaw at our design that permits only 1 connection for the flooded application. 2. An application causing the tomcat server to hang, exhausting our cpu resources to 100%, trigerred by Stop command from manager. Even after shutting down the tomcat, the process is still running and we have to manually kill the java thread. Thenwe found out that our application got an infinite loop bug when we force it to close. On 1/12/07, Steve Ingraham [EMAIL PROTECTED] wrote: I have a similar problem. I would be interested to know what is said about this. In our case we have a web based application that calls up a MySQL database. It is running in Tomcat 5.5.15 on a Red Hat AS 3 machine. Every morning I have to manually stop and restart Tomcat. If I do not do so and let it run, over the course of a day or two, definitely no more than the third day, Tomcat will lock up and the web application will display access errors to the users. I then have to run the shutdown.sh script on Tomcat. Then because the instance will not clear out I have to run ps aux, find the instance of java that is running. I then have to run the kill -9 pid # command and then startup.sh to restart Tomcat. If I do this first thing in the morning Tomcat will function without locking up. If I do not do it first thing in the morning, sometime during that day, or if I am lucky the next day, Tomcat will lockup. If anyone has ideas on what can be done to correct this problem I will be anxious to read any replies.
