Hello Jeff,

I realize that this bug report is close to useless but I don't think we
have time and resources to do much more. Hopefully we can dig out which
mpi call was involved and some more details. If you have any commands or
lam options we could try that would be of the copy-paste-run-wait type
I'll try to run them.

/Peter
