I got the following error message running MPICH on an SGI:


Timeout in waiting for processes to exit.  This may be due to a
defective
rsh program (Some versions of Kerberos rsh have been observed to have
this
problem).
This is not a problem with P4 or MPICH but a problem with the operating
environment.  For many applications, this problem will only slow down
process termination.

I am running a program with seven processes, each of which runs for
about one hour, with little communication.  After getting this message,
MPI appears to exit, but a ps command reveals that several processes
continue to run for several minutes.

Can anyone tell me what is causing this message and what it means?
