Tomcat version 6
Apache 2.2.3
Centos 5.2
VMware 2.5
2 VPU's
4G Memory

Guest Memory usage is on a avg 122 MB and Host Memory is at 3.31 G so we
know it's not the balloon driver.

Problem statement:

I understand as a SysAdmin that the JVM loves to grab all the memory
resources as it can, sort of like Oracle.  However when we stop and then
attempt to restart Tomcat it fails and the server needs to be restarted. 
Also it seems that this memory is being held in the Linux Cache system and
to release it we run the following:
echo 3 > /proc/sys/vm/drop_caches

I guess my question is there a tuneable on either the OS or in the JVM that
will give me the same result?


Let me know any more information I need to provide.

Thanks,

Marc Sweeney
