Message 31419 - Posted: 15 Jul 2017, 20:21:35 UTC - in response to Message 31417.  

I'm still looking for jobs (not necessarily tasks) that failed after about 1500 UTC today.

okay, so we'll see what the logs show tomorrow.

Message 31420 - Posted: 15 Jul 2017, 20:25:41 UTC

Another suspicious one got finished a few minutes ago:

https://lhcathome.cern.ch/lhcathome/result.php?resultid=151051271

Runtime is 3 hours longer than CPU time. There is definitely something wrong.

It seems that there is an error in the stage-out phase.
I saved stderr.log and stdout.log of my currently running WU.
Let me know if they are of interest.
Can't hurt to have them. Do you have my Brunel or CERN emails? Otherwise PM me.


My WU decided to finish it's break while I was typing the message above.
So, at the moment it is running normal.

OK, the job that started at 2017-07-15 15:14:14 seems to have taken an excessive amount of time, but didn't actually fail as far as I can see. I'll tickle Laurence, but don't expect any response this time on a Saturday night.
[Edit] I have to go sleep soon, so don't expect anything more from me for 9-10 hours, unless inspiration strikes in my dreams! [/Edit]

good morning, Ivan.

Here the next example: https://lhcathome.cern.ch/lhcathome/result.php?resultid=151087801

Runtime 14 hours 6 minutes
CPU-Time 9 hours 52 minutes

This is totally abnormal and different to what it has been before:

https://lhcathome.cern.ch/lhcathome/result.php?resultid=150602181
Runtime 12 hours 43 minutes
CPU time 11 hours 55 minutes

You are exactly right, it's a stage-out problem, connecting to Data Bridge. This was, of course, strongly suggested by the pie graphs in the Job Activity page. I'll pass the files on to Laurence. There's another recurring error, seemingly from a typo in a script, but I'm not sure if it's one of ours, nor if it has serious repercussions.

OK, we've done our bit; now we wait. I'd suggest people set No New Tasks or temporarily transfer to other apps/projects to minimise wasted time.

Thank you, Ivan, for your efforts (I knew that something was going wrong).

Cheers, Erich; I do my best but I can't do everything. It's just gotten worse, which may or may not indicate that someone's trying to do something. Lunchtime at the cricket Test (England vs. South Africa) so I'm off downtown for my shopping, back in an hour or so.
[Edit] Well, it's definitely got worse now. "Watching and waiting," as the Moody Blues sang. [/Edit]

I'm afraid I have no idea, Erich, it's well beyond my control. Set No New Tasks, batten down the hatches, and check back tomorrow. :-(

Just now another CMS got finished and uploaded (one of the last remaining ones I had in the queue on one of my machines). The interesting thing is that they do not fail (which is good, on one hand).
Also here, the discrepency between total running time and CPU time is nearly 4 1/2 hours.

I'm not seeing failures as my tasks run out, but the Dashboard graphs definitely are not showing any hint of green. But then again Dashboard is not always up to date. I'll keep monitoring but I'll probably go to bed relatively early, I've got a lot happening tomorrow.

Tja. A Group meeting. Three reports to write (including CMS@Home). Five or six servers to do security updates on. Two 4 TB disks to RAID into one of the servers if I can get hold of a couple of CMOS batteries for the matched-pair that are having the Intel equivalent of Alzheimer's. And a doctor's appointment. As well as trying to get the current stage-out problem fixed.

Only that the LHC@Home crew is aware of it and working on it. I'll let you know as soon as I hear anything.

We are staging out jobs again, and the Data Bridge Web interface is working. Please proceed cautiously, but it looks like you can start running tasks again.
