JDK 1.4 Keeps Crashing.

Have you been trying to view this site and received timeouts or 500 Internal Server Errors? If so, I apologize and hopefully we've found a remedy for it. I found that this site seems to crash at least once a day, and sometimes several times a day. When it does, I've found the following error in my logs.

#
# HotSpot Virtual Machine Error : 11
# Error ID : 4F530E43505002D5
# Please report this error at
# http://java.sun.com/cgi-bin/bugreport.cgi
#
# Java VM: Java HotSpot(TM) Client VM (1.4.0_01-b03 mixed mode)
#
# An error report file has been saved as hs_err_pid3103.log.
# Please refer to the file for further information.

The admin, Keith, at my hosting company first suggested that we downgrade from JDK 1.4.0 -> 1.3.1. I've had no problems with 1.4 on other projects, so I didn't want to do that. So Keith has been nice enough to schedule a cron job that checks the status of this site every minute, and if it can't load a JSP, then it restarts everything. Hopefully this helps. I hope this isn't related to Roller, and I doubt it is as everyone else seems to be running fine.

I'm getting the same error running my struts app on tomcat 4.1.12, java 1.3.1. Can you share the script that checks the status and restarts everything if it doesn't repond. Thanks, Richard

[Trackback] Well, the JVM crashed yet again. It's better thought, down to 1 crash today, from the whopping 4 yesterday. The problem with error 11 (segfault) is that, when googling for it, one finds many people with the problem and no one ... [Java, 1761 chara...
