First finding that narrows things down: - On the cluster, jobs seem to work fine with normal tasks (#.rec files = #jobs). It caps at 100 when --wordlist=<dict> is used. - I cannot reproduce this on the very basic lab setup (#.rec files = #jobs). However, the output is slightly different when a wordlist is used: --- bofh@...ncher:/opt/JohnTheRipper/run$ rm *rec; mpirun -np 120 ./john --format=raw-md4 /tmp/hashes <SNAP> Loaded 1200 password hashes with no different salts (Raw-MD4 [MD4 128/128 SSE4.1 4x3]) Using default input encoding: UTF-8 Node numbers 1-120 of 120 (MPI) Send SIGUSR1 to mpirun for status --- If the job uses a wordlist, "Send SIGUSR1 to mpirun for status" is missing. >Oh BTW it's very strange you can resume such session with (seemingly) no >problems.

On the console everything looks normal: Remaining X password hashes with X different salts Cost 1 (iteration count) is X for all loaded hashes MPI in use, disabling OMP (see doc/README.mpi) Node numbers 1-640 of 640 (MPI) <session status messages> However, this message pops up in john.log for a number of workers: "Terminating on error, recovery.c:165".
