Antonio, Rajeev and others,
thanks for your replies and comments on possible causes for the
error messages and failure, I have passed them on to the
programmers of the underlying application. I must admit I do not
understand what unexpected messages are (I am but a mere user),
could you perhaps give examples of typical causes of them? Eg, the
cluster it runs on consists of 3 dual xeon computers with varying
cpu clock rating - could these error messages be due to getting
out of synch, expecting results but not getting them from the
slower computer? I have re-started the process but excluded the
slowest computer (2.27GHz, the other two are running at 2.87 and
3.2) as I was running out of ideas.
For your information, this runs well on smaller problems (few
computations).
Thanks,
Ron

It looks like at least one of your
processes is receiving too many unexpected messages, leading
to get out of memory. Unexpected messages are those not
matching a posted receive on the receiver side. You may
check with the application developers to make them review
the algorithm or look for any possible bug.
