WMCore want to update our WMAgent, but the current workflow won't end for over a week, So, we'll have to force-stop the w/f which will mean running tasks will be lost. I'll try to give at least a day's notice of this, so be prepared to set No New Tasks when I have a deadline to work with.

---

OK, I've told WMCore that they can shut down our workflow for the upgrade anytime after 1200 tomorrow (CERN time). Please set No New Tasks ASAP.
I'll let you know when it's safe to go back in the water again.

No action yet from WMCore, and many people are still running tasks, it seems, This workflow will probably finish over the weekend. I'll start injecting smaller workflows then, so as not to have too much interruption when the intervention does finally occur.

It looks like this will finally happen tomorrow night (CET). I'm letting the queues drain.

CMS tasks can be downloaded again, but they fail after a few minutes, with error

Mine are all working for the last 3 hours Erich

that's really strange; just now, I tried again, same negative result:

"Error reading proxy credential"

what's going wrong since they were fiddling around with the WMAgent ?
(BTW: Just to be on the safe side: for another test, I switched off my own squid proxy, so the task got connected directly to the internet - same negative result)

Edit: just tried a Theory task: seems to work well

Same problem as by Erich56: all CMS tasks are failing, Theory works

interesting, that CMS works with some volunteers (like Magic Quantum Mechanic) and does NOT work with some others :-(

Yes, a bit of a head-scratcher. I'm reaching out to People Who Should Know(®).

many thanks, Ivan :-)

Well all of mine were working and almost 100 Valids BUT as soon as I am not watching now I am getting that same thing again (same thing with the -dev version)
