as a test 10 minutes ago shows, there are still no jobs available, but tasks are still being distributed - the automatic stop of tasks distribution again does not work.

The result looks like this:
https://lhcathome.cern.ch/lhcathome/result.php?resultid=405292196

On the project status page one can see 345 users within the past 24 hours (and almost 13.000 tasks being processed), so that many users have been crunching CMS tasks which run only in the "envelope" and finish after some 25 minutes, with NO VALUE at all for the science :-(

Holpefully this nonsense will be stopped ASAP.

Task is running 25 minutes and cmsRun inside VM 13 minutes now (95% Cpu)
You were more lucky than I was: The task I started did not error out like the others before, but obviousla there were not jobs available. The task finished after 29 minutes with just about 1 minute CPU:
https://lhcathome.cern.ch/lhcathome/result.php?resultid=405220625
in view of the fact that obviously no jobs are available, would't it make sense to stop distribution of tasks ?
I tested again this morning, and still the tasks finished after about 25 minutes because no jobs could be downloaded. What I am wondering is that this time the automatic tasks submission stop does not work.

It seems something is fixed. I've a CMS job running inside a BOINC VM now.
for how long has the task been running now?

still the question is what one should do with all the tasks that have been running for 10 hours and longer without finishing.
Aborting them because they most probably are dead ?

I started another task, and after 23 minutes it failed:

So things are still not working the way they are supposed to :-(

We've decided to roll back the changes from this morning, to try to get a handle on what didn't go the way we thought it would. Keep us informed if anything doesn't revert to "normality".
Ivan, how about the tasks that have currently been running for many hours withoug finishing yet? Will they ever finish, or should they be aborted in order to allow newly downloaded tasks to get started ?

just seeing several failed tasks on one of my machines; they failed after about 20 minutes - see here:

https://lhcathome.cern.ch/lhcathome/result.php?resultid=405218808
looks exactly like when tasks receive no jobs - is there, in addition, a problem with jobs submission?

just giving a closer look at one of my faster systems (CPU Intel i9-10900KF running at 4.6GHz):
tasks which before were finished after 2 1/2 and 3 hours now are running more than 6 hours already, CPU between 0.3% and 0,7%, and no idea when they will get finished.
Seems strange ...

Has there been any change in the CMS tasks recently?

The reason why I'm asking is: since this morning, I notice that the tasks on all of my machines are running considerably longer than usual (so far, more than double time, and still not fnished yet), with almost no CPU usage.

Post:
Any idea what kind of problem I am experiencing ?
Do you use a seperate home, school or work preference and ticked 'native'?
many thanks for this valuable hint :-)
Indeed, I had ticked "native" about a week ago when I tried to run Theory on Linux which I had installed in a Virtual Box on one of my PCs (however, it did not work since several additonal files were missing, according to the stderr of the few failed tasks [e.g.: https://lhcathome.cern.ch/lhcathome/result.php?resultid=404640160])

Anyway, I now unchecked "native", and Theory tasks for Windows were downloaded right away.

Due to lack of CMS tasks since last night, I intended to crunch Theory instead.
However, on all of my computers, when trying to download Theory tasks, the BOINC event log says "no tasks available for Theory". The project status page shows nearly 5000 unsent tasks.
Any idea what kind of problem I am experiencing ?

an I thought that it happens only at GPUGRID that licenses/certificates are not being renewed in time before they expire :-)

no tasks available; this time, the automatic stop mechanism for submitting tasks if no subtasks are available seemed to work well.
some time later, new tasks could be downloaded.

Today, again no new tasks ... :-(
