My limited understanding, but free memory is memory the JVM has used before and freed up. In your case, total memory probably went up to 149.31 MB at one point, then memory was freed creating that 38.13 MB free memory. If the sum of Free and Total add up to max, I would worry since that implies at some point, the total memory actually hit max. If this machine has other things going on, you might want to consider watching it for a while and then trimming back the max memory.
There are some people on this list with a phenomenal understanding of the JVM and all it's internals. I'm sure they'll correct me if I got it wrong in any way. :-) --David user080...@hotmail.com wrote: > Hi, > I am using the tomcat manager to monitor the health of the tomcat server.
