After looking at this a bit, this problem is becoming quite strange to me. I don't have any nfs exports in my cluster.conf file, so I don't think that bug applies. But I am seeing really strange data in the backtraces (below) Similar to https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=166109 The thing is, this is a stock RHEL4 U1 Kernel (2.6.9-11.ELsmp) On 64 bit capable Xeon processors, but running on a 32 bit kernel. I can compress the core dump I have and send it, if you like, or run any commands with gdb (and the like) needed.
