Matt,
This is what the qstat command shows for a few jobs that are in hold status:
comment = job held, too many failed attempts to run
I restarted pbs on trillian and so far only 5 jobs have restarted

Hello,
The problems on Trillian persist. My existing job is still in 'H' status. When I tried to start a new job it went from 'R' to 'Q' to 'H' rapidly, and when I tried the interactive job it did the same as last time: said it was ready and then said it was completed immediately.
Thanks again,
-Matt

It looks like the restart of alps didn't fix everything. The logs still
show too many files open:
2017-04-24 16:26:26: [1388] processControlMsg:171: Agent received
placement message on fd 212
2017-04-24 16:26:26: [1388] doAuth:1814: Agent popen failure: Too many
open files
2017-04-24 16:26:26: [1388] setupConn:1839: Agent authentication failure
with host nid00235 port 607
2017-04-24 16:26:26: [21547] get_apsched_info:853: Unable to open
/ufs/alps_shared/apschedNid: Too many open files
And sure enough; it has a lot of open files; mostly pointing to
variations of:
/var/spool/cray/llm/apsys.21547-20170424t081526.436974
(10.131.255.254:/snv/245/var)
I've restarted alps again; you should have enough time to get your job
started before it starts causing errors again.
