I just tried starting an interactive job with these results:

[wrightse@mualhpcp02 ~]$ qsub -I -V -l nodes=1:ppn=8 -l walltime=10:00:00

pbs_iff: cannot read reply from pbs_server

Cannot connect to specified server host 'mualhpcp02.local'.

qsub: cannot connect to server mualhpcp02.local (errno=111) Connection refused

Hi guys,

I’ve checked the batch queue a few times this morning with ‘showq’ and received the error below about 5 times out of 7 in the last hour.  Thought you could use a heads-up.
