Subject: [OMPI users] Problems with Mpi Accept - ORTE_ERROR_LOG

Hi there.

I am developing a server/client application using Open MPI 1.5.3. In a
point of the server code I open a port to receive connections from a
client. After that, I call the function MPI_Comm_accept and on the
client side I call MPI_Comm_connect. Sometimes I get an
ORTE_ERROR_LOG, as showed bellow.

before accept in host hydra9 port name =
4108386304.0;tcp://150.164.3.204:48761;tcp://192.168.63.9:48761+4108386305.0tcp://150.164.3.204:49211;tcp://192.168.63.9:49211:300

MPI 2 C++ exception throwing is disabled, MPI::mpi_errno has the error
code
after accept in host hydra9 error code = 17
MPI 2 C++ exception throwing is disabled, MPI::mpi_errno has the error code

The mpi_errno is 17 and I could not find a clear explanation about
this error. It occurs sporadically. Sometimes the application works,
sometimes does not.

Any ideas?

Thanks
