The VM did not get a LHCb-job within 10 minutes after the VM started.
To avoid running an idle VM for up to 36 hours (max for LHCb) or 18 hours (max for Theory), the VM is killed to free the CPU-core for other BOINC-tasks.

Seems kind of inefficient, although I realize it is way more efficient than it could have been! Still seems like there is a ways to go, so that even the 608 seconds does not have to be wasted.

Still no response from HTCondor. That must be why the average run time for all Beauty tasks is 0.16 hours.

Time to turn this one off for a while.

All LHCb tasks seem to fail on the Windows 10 host while CMS tasks work OK.

Initial time to crunch the WU was given something like a good 5 minutes, after running for a while the estimated time went over the 1 day.

There was an issue with the job submission which resulting in there being no jobs. Hopefully this has been fixed. Thanks for reporting this.

Just tried another one and it looks like the problem still exists. Task number 108722165.

This also happens if your network connection is unreliable. My family thinks that Ethernet is so yesterday and would rather place the network router near the center of the house and cover the house with Wi-Fi. There are several problems with Wi-Fi. 2.4 GHz Wi-Fi does penetrate walls, but it is wrecked by poorly-shielded microwave ovens. 5.8 GHz Wi-Fi does not penetrate walls well, and my computer has too many of those walls between it and the router for 5.8 GHz Wi-Fi to run at an acceptable speed. BOINC handles that unreliability well, but LHC@home does not. This is why I put an item in the wish list that work units would be self-contained instead of having to fetch something from a server in the middle of the work unit.

My internet connection is very reliable, but the problem still occurs. I think this is a problem "on the server side".

This is a little confusing as both LHCb and Theory are using the same infrastructure. Will investigate ...

Looks like it is working for me now. The task has made it past the 608 second mark and is using a full CPU thread.

Thanks for getting the image updated.

Will post again if anything changes.

I've had several LHCb tasks fail recently due to lack of work (e.g., Task 111867891). I've also had some fail due to Condor connection errors (e.g., Task 111867740).

I don't see any issues like this posted on the boards recently and my other hosts running CMS and Theory tasks don't seem to have any problems. Not necessarily a problem for me, but wanted to point it out in case it's indicative of a more significant problem.

Why condor suddenly exited after 48000 seconds on this task https://lhcathome.cern.ch/lhcathome/result.php?resultid=115400084 ?

It run almost 14 hours and did finish several jobs but then failed suddenly. This resulted in EXIT_INIT_FAILURE and no credit.
