Our application on resin/solaris stops responding after couple of hours. I've been looking in various places as to see why this is happening including the garbage collection. As said, I have enabled the GC with the following parameters.
args="-J-ms640M -J-mx640M -Xloggc:gc.log -XX:+UseParNewGC -XX:+UseConcMarkSweepGC

I'm curious to know our application is not leaking memory thus causing resin to respond. I ran our application thru couple of profilers and I can see the objects get collected after they are done. Can any one help me out by looking at the above log to see things are ok with respect to GC. This will help me to troubleshoot in another areas.
I never see Full GC and the resin stops responding even I have 300 MB left. Any help is geatly appreciated.
Thanks a bunch
