I recently hit this same error with CPU pegged at 99%. I could not find a root cause. I have used the content system but only to deploy some small shell scripts.

One place where I've seen large amounts of heap get consumed is when using the Content subsystem to install a very large cumulative patch or EAR or WAR. I think we recently converted most (possibly all) places that access package bits to using streams rather than copying the all of the bits into memory. However, there may still be a few places that copy into memory. Are you using RHQ at all for installing/deploying large packages?

I am seeing the following error in the server log when an agent trys to connect to the server. The server had been running for quite some time (1-2 weeks) and jconsole showed it out of heap memory. I have restarted the server with the HeapDumpOnOutOfMemoryError java option to capture anything if it happens again. Anybody seen this before?

This repeats over and over every few minutes.
