What kind of load does your application handle? I am not processing a HUGE amount of requests, but we server about 6000 visitors a day, 15,000 pages.

Hello-
Has anyone had a problem with Tomcat 5.0.28 crashing on Linux with no error messages?
My production server running with JDK 1.4.2_06, RedHat EL 3.0 just crashes, no core dump, no errors in catalina.out, no clues. Sometimes it goes for days, sometimes it happens several times in one day. I am running the tomcat process behind Apache 2 with mod_proxy. Setting "ulimit -c unlimited" in the catalina.sh startup file still did not produce a core file.
If nobody else has experienced this, do you have any suggestions on how to debug it further?
Thanks,
Greg

I'm using the same setup as you less Apache2. I use tomcat as the web server. Using TC5.0.28 and JDK1.4.2_06, and I have yet to have the server crash once. Not much help, but might give you some clues where to look.


Connector log (mod_proxy....assuming you mean you're using the new connector code)....is there anything in the Apache2 log? I assume from your post you mean that the java process just completely goes away. You might find (depending on the running directory of the java process running tomcat) a pid dump log file or something...not sure if the vm produces one of these or not. You also might check in /var/log/messages file to see if for some reason the kernel or some lib got some error it logged.
