Subject Max Memory Reading
Date Fri, 13 Oct 2006 07:14:35 GMT


I was having some problems with perm gen space on one of our tomcat
instances and decided to increase the perm gen size and review the
JAVA_OPTS settings in general when I noticed something curious.  No
settings are currently made so its just running with default values, but
the manager status page shows the following...

>Free memory: 158.53 MB Total memory: 373.75 MB Max memory: 913.37 MB

That max memory figure in particular looks like a pretty strange
default!  I thought  the default was 64m.  

The installation details are as follows...
Apache Tomcat/5.5.16 1.5.0_06-b05 Sun Microsystems Inc. SunOS 5.9 sparc
The system has 16G of RAM.

Has anybody any thoughts?
