MPI error
 

I am using Star-CCM+ and receiving the following error.

Any suggestions on what could cause this would be appreciated.

------------------------------------------ unable to read the cmd header on the pmi context, generic socket failure, error stack: MPIDU_Sock_wait(2533): The specified network name is no longer available. (errno 64). received suspend command for a pmi context that doesn't exist: unmatched id=4. --------------------------------------------
