Curious as to why the 6 CPU application task says 20 minutes were remaining but the last few from 99.75% have taken days to accumulate? Is this particularly normal with LHC Atlas tasks?
I've paused other tasks to possibly allow for extra resources to be given to the LHC application with no observable affect.

I think if you have don't done many tasks then there is error in how the remaining time calculated, it should get better over time.

I have the same problem 5 CPUs task done in 100%, working time so far 3 days 4:57:58 and still counting althout ending time shows 00:00:00 all other tasks are stopped ...

This is most likely caused by too many suspend/resume cycles.
See the logs from ATLAS/CMS.


You got a mix of different tasks.

Theory: works fine
see:

https://lhcathome.cern.ch/lhcathome/result.php?resultid=354202802



CMS: works fine
https://lhcathome.cern.ch/lhcathome/result.php?resultid=354214457
except that CMS (and ATLAS) don't like to be suspended too often or for longer.
This may become a problem in the future.

ATLAS
WUs like this are caused by a CERN configuration error:
https://lhcathome.cern.ch/lhcathome/workunit.php?wuid=188417240
Just ignore them.




These are fine as they returned a HITS file:

https://lhcathome.cern.ch/lhcathome/result.php?resultid=354295020

2022-05-12 16:40:00 (11588): Guest Log: HITS file was successfully produced




The last one suffered from suspend/resume described above but finally succeeded.
Nonetheless it was close before a crash.
