failed to poll for a spawned proc

I am using openmpi, but after the recent upgrade I get these error messages:

[hpc-3-6.local:27247] pls:tm: failed to poll for a spawned proc,
return status = 17002
[hpc-3-6.local:27247] [0,0,0] ORTE_ERROR_LOG: In errno in file
rmgr_urm.c at line 462
[hpc-3-6.local:27247] mpirun: spawn failed with errno=-11

You are still using the "-hostfile" or "-hosts" parameter for mpirun in your job submission script. Remove it.
