You should produce a Stack trace of your server when things are slowing down.

Add -XX:+PrintClassHistogram to your VM Options. and call kill -3  when the process is getting slow (before it crashed).

-XX:+PrintClassHistogram or kill -3 wouldn't hurt your production system. But if you can replicate this on a test environment it's better.

You are probably running out of memory. I used to work with Solaris years ago, and running out of memory would certainly crash the VM on Solaris.
