I qdel'd my job and submitted a new one to the queue.  It did the same thing: 'R' to 'Q' to 'R' to 'Q' and then to 'H'.  I watched it as I spammed qstat.

Below is the printout from qstat -a and xtnodestat.  There seems to be something deeper wrong.  Half the machine is empty but look at the queue.  Also, what is going on with the interactive run going from ready to complete with nothing happening in between?

Thanks,

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.
