Comment 2 Jeff Moyer 2006-01-09 18:15:30 EST
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?
Comment 3 Dave Theodore 2006-01-10 00:20:44 EST
It hasn't happened since and I have set it to save a core, so hopefully we'll
get something more the next time.
Comment 4 Jeff Moyer 2006-05-23 13:19:56 EDT
I'm still waiting for more information on this.
Comment 5 dan ginsberg 2006-05-23 13:37:17 EDT
Has not yet recurred.
Comment 6 Jeff Moyer 2006-08-08 15:47:13 EDT
Given that we are unable to reproduce the problem, and RHEL 3 is not receiving
further updates, I'm closing this bug.
