Is your code multithreaded?

Thanks alot for your reply,

I'm using blocking Send and Receive. All the clients are sending data and the server is receive the messages from the clients with MPI_ANY_SOURCE as the sender. Do you think there is a race condition near this pattern?

I searched a lot and used totalview but I couldn't detect such case. I really appreciate if you send me a link or give an example of a possible race condition in that scenario .

Also, when I partition the message into smaller parts (send in sequence - all the other clients wait until the send finish) it works fine. is that exclude the race condition?

Regards,

Amr
