Thanks for the quick reply. The default values aren't of too much help
I'm afraid - the machines I'm working with are on an academic cluster,
and the JVMs are not typical on the machines. The jconsole tool,
though, will be a big help. I found another way (albeit, somewhat
hacked) to get the default max heap - if you keep setting the Xms
option higher and higher, it will error when you go above the default
max heap value. However, I never knew too much about the jconsole tool
- I think that it will be helpful for a lot of other monitoring stuff
that I need to do soon. Thanks again!
