Hallo,

I have installed mpich on a network of SPARC WS.
Everything works fine when the machines load due to other users is small
(night, week-end,...).
If the load is big, however, I get often the following error messages:

mpirun -np 10 testParallel
p4_405:  p4_error: Timeout in establishing connection to remote process: 0
rm_l_0_406:  p4_error: interrupt SIGINT: 2
 
or something like ... permission denied...
or ...failed to fork try again later...

Why ??? Is there a way to avoid such problems ?

Thank you very much for your answers !!
