Its a long shot but could it be related to the total data volume ?
ie 524288 * 80 = 41943040 bytes active in the cluster

Can you exceed this 41943040 data volume with a smaller message repeated more often or a larger one less often?

Not so far, so your diagnosis could be right. The failures have been at the following data volumes:

41.9E6
4.1E6
8.2E6

Unfortunately, I'm not sure I can change the repeat rate with the OFED/MPI tests. Can I do that? Didn't see a suitable flag.

In any case, assuming it is related to the total data volume what could be causing such a failure?
