[Pw_forum] From davcio: error #10

Alright, so it's follow-up time.

After looking over which of the 25 runs finished (4 of them did), and moving
them to a separate directory, I re-submitted the runs to the queue.  This
time, apparently 7 of them have decided to stick and do a run.  No
guarantees on them finishing, but it looks promising as the error typically
evolves for me after the wavefunction collection (wfc) call in the output.
So the question now becomes: if the input files are working properly when
they decide to stick, what could be causing them to not stick?  The outdir
is the same for every input file, so I suppose it could be just too busy
with the calls from all of the different runs.  Has anyone else had issues
with this?  Moreover, is there a limit to how many runs I should direct to a
specific outdir?  Would it be better to assign a unique outdir for each
run?  Thanks!  I appreciate all of the help.

Most Sincerely,

Patrick
