Thanks for the response, Ralph. I checked my application and it seems not have a race condition in the accept stage. The server is started and it stores the port name in a file. When a client is started, it gets this port name and tries to connect. In my tests the error happens about 1 time in 10 executions.
It still working without confidence. On Tue, Jun 28, 2011 at 11:10 PM, Ralph Castain <r...@open-mpi.org> wrote: > Looking deeper, I believe we may have a race condition in the code.
