Dear All, I have installed openmpi-1.3.1 (with the defaults), and built my application. The linux box is 2Xamd64 quad. In the middle of running of my application, I receive the message and stops. I tried to configure openmpi using "--disable-mpi-threads" but it automatically assumes "posix". This problem does not happen in openmpi-1.2.9. Any comment is highly appreciated. Best regards, mahmoud payami
