Oh, I'm not "blaming" either one. Normally, our server is quite adequate to handle the expected user load. Every now and then we get a "perfect storm" of too many users asking for too many large-memory requests, and an OOME happens. We're investigating ways to increase capacity, but in the mean time, automating recovery would help keep the 3am phone calls from happening.
We're running Java 6 and Tomcat 6. It's definitely heap space that's running out, and we're actively profiling various load scenarios to spot the most likely targets for memory-use reduction. But again, a short-term technique to automate the restart would help a lot. -----Original Message----- From: Caldarale, Charles R [mailto:[EMAIL PROTECTED] Sent: Tuesday, July 31, 2007 10:00 AM To: Tomcat Users List Subject: RE: Recovery from OutOfMemoryError? > From: Craig Berry [mailto:[EMAIL PROTECTED] > Subject: RE: Recovery from OutOfMemoryError? > > Fixing the bug would be cool, but the "bug" is actually just too many > users contending for the same heap space Let's put it another way: your webapp and/or JVM configuration aren't set up properly to handle the number of users you have; don't blame it on the users (or Tomcat). What JVM do you have installed? What version of Tomcat? What OS? Are you sure you're out of heap space, or is some other resource being exhausted, such as file handles? If it's really heap space, is it the PermGen? Do you have a memory leak in your webapp? Have you profiled what's going on to see the real cause of the problem? - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
