Memory Problem...

hughesfleming — Thu, 08 Feb 2007 16:44:17 GMT

I have installed Alfresco community edition via the war into an existing tomcat installation running Centos 4.4 x86_64 and jrockit_x86_64 (latest build). The server is an HP opteron server with 4 gigs of memory. The jvm is configured with the following: JAVA_OPTS="-Xgcarallel -XXcompressedRefs -Xm

Hi,

Tomcat runs in a VM that has a maximum memory limit. The VM should not grow much beyond that. This is a VM-specific issue. You might try another VM just to be sure.

We ran some benchmarks with JRockit and didn't have any issues, so it might be OS or configuration dependent as well.

Have you tried the standard Sun JDK to ensure that it is not JRockit at fault? This morning I performed a multi-threaded stress test on Alfresco 2.0 HEAD designed to find memory leaks and after 50,000 web-client screens requests no signs of a leak was detected. Note that was TomCat 32bit with SunJDK 1.5.0_09.

Thanks,

Kevin

I am now running on the Sun 32-bit JVM and everything seems to be working fine now.

Thanks for the help,

Alex

Alex, could you post your Java options? I have a similar problem (see my post: http://forums.alfresco.com/viewtopic.php?t=5276)

Thanks.
