I'm running on linux (Centos 4), condor 6.8.6.  The bash builtin ulimit
reports "unlimited", and I've not configured any specific limits on the
nodes, besides which condor_master starts as root (then child processes
drop to the "condor" user).  

My LOG dir is an NFS mount on the compute nodes (back to a central
server, for ease of management).  I've double checked, and there's no
core files in any of those directories; I wouldn't have thought being an
NFS mount would stop core files being generated, but would welcome any
suggestions to the contrary.

Nothing at all that looks promising; the last line before the restart is
often a state change, but the current level of logging means that's not
entirely improbable.  I could ramp up the logging level and see if that
helps, but I guess unless we can get a proper core dump, I'll still be
guessing as to the cause.
