It usually has 160 MB to 220 MB of memory allocated (these figures are from top, so room for some error). The system is under pretty heavy traffic when it starts up. I have maxProcessors set to 384 and minProcessors set to 50. > Since you have free system RAM left, then it sounds like > your 896M is too small for the load. Problem is, if I increase -Xmx and don't touch anything else, I get this OutOfMemoryError too. The system has 1.2 GB to 1.4 GB of memory free when this error occurs. > Do you load balance Tomcats across machines? Or are you > running all these users against one Tomcat? Just one Tomcat and MySQL on the server.

My mistake...I am thinking of the variable name *I* use in a script that passes this to CATALINA_OPTS. I am really sorry for that confusion. Have you verified that at the time of the Out of Memory errors that the JVM is somewhere near 896M RAM? How about when it starts up and there is little or no traffic? Is it at or above (probably above) 384M? Since you have free system RAM left, then it sounds like your 896M is too small for the load. Do you load balance Tomcats across machines? Or are you running all these users against one Tomcat? If you could spell out the setup in a bit more detail, I might be able to help you figure it out and possibly how to fix it.
