I'm afraid this isn't really enough information to go on. Has this occurred more than once? Can you get a kernel crash dump if/when it happens again?
It hasn't happened since and I have set it to save a core, so hopefully we'll get something more the next time.
I'm still waiting for more information on this.
Has not yet recurred.
Given that we are unable to reproduce the problem, and RHEL 3 is not receiving further updates, I'm closing this bug.
