One minute before I see: Jan 4 01:52:10 zinc.ee.lbl.gov kernel: : pid 21007 (conftest), jid 3845, uid 0: exited on signal 11 (core dumped) but I see a lot of those and I believe they're normal and autoconf related.

And in my case the system is located in a data center that I do not have casual access to so I'm happy to make the tradeoff in favor of system resilience. Craig
