Also can you post your JVM arguments and how much physical memory do you have on your server.

LR 6.0.6 CE + Linux 64bit + MySQL Server 5.0.51

VM arguments are the one by default from liferay Out of the box.
I read in tomcat/bin/setenv.sh : JAVA_OPTS="$JAVA_OPTS -Dfile.encoding=UTF8 -Duser.timezone=GMT -Xmx1024m -XX:MaxPermSize=256m -Dexternal-properties=portal-legacy-5.2.properties"

I precise this liferay is from a migration (a 5.2.3 CE original LR to a 6.0.6 CE LR)

And the output of `free -m` command


climact@climact:~/liferay-portal-6.0.6-climact$ free -m
             total       used       free     shared    buffers     cached

Thanks

You might want to check one of these threads,

Thread1

Thread2

Thread3

Or else You need to set JAVA_OPTS i guess

example:
SET JAVA_OPTS= -Xms128m -Xmx512m;

And also set the following in your build.properties

javac.compiler=modern
javac.fork=true

Are you using Oracle JDK? OpenJDK sometimes seems to give error.
One of my customer was having some problem with JVM on a 64bit linux, but their JVM was aborting so it doesn't seem to be the same.

Is it just vanilla Liferay tomcat bundle or have you deployed additional portlets too? I'm running several 6.0.6 instances with 768m to 2G of heap. You just might need to allocate more memory based on how many concurrent users you have and what functionality you use.
