Hello everybody

I'm using the MPICH version of MPI von Sun Workstations under 
Solaris 2.5 and on multiprocessor PCs running Linux. Starting
the programs with the 'mpirun' script, we frequently see on both 
systems at least one process hanging in the 'MPI_Init' function.
Further inspections with the debugger reveals that it is blocked
or polls on some network service.

Does anybody saw a similar behaviour or can tell me what's
going wrong ?


Thanks in advance,

Marcus Dormanns
