When trying to run the CFX-Solver in parallel on Windows using the MPICH version, the run fails with the following error:

Error 32, process 0, host VORTEX:

CreateFile failed: .mpi3.tmp

Wait for process 0 to write port to temporary file timed out

An error has occurred in cfx5solve:

The CFX-5 solver has terminated without writing a results file.

Running the PVM version of the solver, or running in serial mode, work as normal.

This problem is known to occur on some Windows machines running the Symantec Antivirus software. It appears that the creation of the mpi temporary file is delayed by the intervention of the antivirus process, and this causes the solver run to fail with what is essentially a timeout error.

No workaround is currently available.

A modified MPICH library for Release 10.0 is available.
