I 've got the same problem as described in:

The problem seems to occur randomly! It occurs more often if I use a
larger number of cpu, but always never if I use a small number of cpus.
So far my cure to the problem is to kill and restart my application
(mpirun ...) as often untill the error won't occur and mpirun will run.
So is the problem resolved. Can anybody give me an hint?
I am using a amd64 linux (suse10) cluster with infiniband conection and
openmpi-1.2a1r10111.
I attach the ompi_info --param all all output, hope it helps.
Regards Jens
