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 On 24/05/2014 3:10 AM, Rajeev Thakur wrote:

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.
