[Linux-cluster] cluster failed after 53 hours



My 3 node cluster ran tests for 53 hours before hitting a problem.


Node cl031 hit the 1st problem CMAN: killed by STARTTRANS or
NOMINATE.  There is a DLM assert on cl031 also, but that is
after a whole bunch of debug output.  The full logs are
here (http://developer.osdl.org/daniel/GFS/test.12jan2005/)

Any ideas on what is going on?

Here is simplified output (in the README file):
test started Jan Wed 12 17:18
hung after Fri Jan 14 22:00

cl031 got an error in just under 53 hours.
