Thanks to the unknown brave knight who fought the "empty queue dragons" last night and provided fresh work.

... and provided fresh work.
the question is: how long will this nice situation last ???
(I admit, this is a rather pessemistic question - but I've become quite pessemistic meanwhile, concerning many aspects of LHC crunching)

when I remember how often this has happened in the past - CMS is definitely not a well working sub-project :-(

and once more my question: what happened to Ivan? Does no-one know?

Ivan is not having a very good personal life at the moment. :-(
I'm keeping jobs available, and I'm aware of the dips in the jobs graphs (plus you may have noticed a network interruption at CERN last week). These are due to HTCondor not matching worker machines to job requirements. There are some indications that it depends on available memory, but that can't be the full story because my machines stop getting jobs during the lulls but then build up again afterwards. I'm trying to get a condor expert to look at it.
Sorry for your frustration, I feel it too but I have deeper problems to worry about at the moment.

I hope not related to the fires. Anything is better than that.
Good luck.

I am sorry to read this, Ivan :-(
And thanks that you, nevertheless, are taking care of CMS.
Let me wish you all the best for your personal situation (whatever it might be).

Seems like this is back, best to set NNT for time being.

Hmm, something curious there. The current batch should have been 10,000 jobs but only 7,300 have been created, so we started running out overnight. Apologies for that. I've submitted a new batch so more jobs should be available soon.

That is a few hours drive from us. We have visited it once. Or maybe it was again and again.
I don't remember.

Sorry, I don't know what's going on. There are plenty of jobs available but the server doesn't seem to want to send them out.

It is about the same on ATLAS and Theory. I am within an hour of running our of work, and can't get any more.

EDIT: I just picked up a few Theory, but not enough to fill the buffer. That has been the story for some time now, now matter how I set the buffer. I can never get more than about 3 hours of work.

CMS subtask queue is empty again.
I set my CMS clients to NNT until the queue is refilled.

Yesterday evening CMS started to send out subtasks again and all of my clients could get some of them but during the night the servers sent them out only occasionally.
Grafana shows there are about 200 running jobs which is far less than during the good days before.
