LHC@home BOINC servers will be down for a while later today due to a database intervention.

Post:
This problem seems to be with older BOINC clients that include old ssl certificate bundles. If removing and re-attaching to the project does not help, please consider upgrading to a more recent BOINC client version.
6) Message boards : ATLAS application : atlas error (Message 50292)
Posted 30 May 2024 by Profile Nils Høimyr
Post:
We do have a new server running the ATLAS assimilator and validator, but not have any changes to the upload/download servers for months. Could it be a scheduler issue?

My own clients do not get this error, and as far as I can see not our other servers either.

Would suggest to detach/remove LHC@home and re-attach to the project if you observe this as suggested by Crystal Pellet.

Edit: BOINC client 7.20.2 does not have any download issues.

Post:
Sorry for these validation errors. We had a problem with the ATLAS validator yesterday on our new server. We have now set the relevant results to re-validate in the database. Hopefully you should get credit soon, unless something else prevents it.

Post:
More recent web servers may have a default limit of 1GB, while there was no limit in the past. We have increased the limit to 2 on our latest file servers, so uploads should normally work on the next attempt. However, if the squids are limited too, you might be blocked earlier.

Post:
Our file servers ran out of memory with the big batch of hits files. Sorry for this. We are adding more file servers today, so please retry uploads later.

Sorry for this, we have added more file servers, so hopefully the upload for those tasks should work now if you retry.

We have added swap on most of the file servers, so hopefully they should finish uploads and not crash.

Post:
We are still trying to debug the file upload blocker on the servers, as we have not set a limit, but the httpd process crashes during these uploads. What is strange is that we have not seen these mpm prefork crashes before, probably because the files were smaller. It looks like the servers run out of memory during the upload.

Post:
As far as I can see, this is not on the project side. On our servers the DB-dump jobs are running and the contents of the html/stats directories of the 2 projects different. (Orders of magnitude more hosts and users for LHC@home than our dev project.)

The link has been updated to point to the production MC plots server. (The dev server that was there before had some issues, ref. this post. )

The LHC@home BOINC servers will be degraded on Monday 18th of September due to a database upgrade. BOINC clients are likely to generate errors when trying to download or upload tomorrow morning.

The LHC@home team wishes you all a Happy New Year and all the best for 2022!

The simulations carried out under LHC@home contribute to improvements to the LHC accelerator as well as the experiments. The upcoming Run 3 of the LHC shall start soon.

Meanwhile you can take a look at this video with highlights from CERN during 2021.

Many thanks for your contributions and happy crunching!
