Problem writing CMS job results; please avoid CMS tasks until we find the reason
Since some time last night CMS jobs appear to have problems writing results to CERN storage (DataBridge). It's not affecting BOINC tasks as far as I can see, they keep running and credit is given. However, Dashboard does see the jobs as failing, hence the large red areas on the job plots.
Until we find out where the problem lies, it's best to set No New Tasks or otherwise avoid CMS jobs. I'll let you know when things are back to normal again.

CMS jobs
The batch I submitted last night is now showing on the monitor, so you can resume tasks at will.

Warning: possible shortage of CMS jobs - set No New Tasks as a precaution
There was an intervention (i.e. upgrade) yesterday afternoon[1] on the cmsweb-testbed system we use to submit CMS workflows that left things a bit confused. One problem was fixed, and the monitor shows all good. However, we are running out of CMS jobs -- maybe 10 hours left -- but the new batch I submitted yesterday isn't showing up on the testbed monitor. I submitted another last night but still neither are being shown this morning, so I submitted yet another batch.
At the moment I don't know whether the submission has failed or whether the monitor hasn't picked up the new batches. As a precaution, set No New Tasks on your CMS project(s) to avoid tasks crashing due to lack of jobs. I'll let you know as soon as I'm sure jobs are available again.

[1] How many times do I have to tell people not to touch critical systems on a Friday -- especially Friday afternoon!?

Dev server updated
We have updated our development server to the latest BOINC server release.

Please let us know if you spot any issues.

The server may go down for a while if we need iterations on this.

ATLAS load tests
For information: We have increased limits pr. host on the dev project as part of a campaign to test our new storage backend.

Expect most new ATLAS tasks to be pulled by our local cluster hosts and the LCG cluster in Bejing. But there are tasks for other applications too for those interested. There might be interruptions too, as this is our development and testbed. :-)
