Kernel version: 5.14.21
Boinc 7.18.1 w/VirtualBox 7.0.6, both sourced from openSUSE repositories.

Since just before 12:00 UTC on 12 May, my system has not been fetching more than one work unit at a time. So long as I have one WU running, any fetch try fails with "Don't need()" Event log extract as follows:
Mon 15 May 2023 03:48:04 PM | LHC@home | Scheduler request completed
Mon 15 May 2023 03:48:04 PM | LHC@home | Project requested delay of 6 seconds

I have reset LHC in Boinc to no avail -- I received one Atlas task only, and setting my project preferences to Theory only did nothing.
I am at a loss as to what to try next. I thought perhaps I might need to delete and reinstall the LHC project in Boinc, but thought I should ask in here first in case there is something else I might try first.

Have set prefs to Atlas and Theory and get both or one of them.

I forgot to say that I set it back to getting both.
That still doesn't solve the problem, which is no matter what I do, I only receive one WU at a time, and I will not get another one until that has been reported.

OpenSuse does not distribute official BOINC or VirtualBox packets for Leap 15.4.
What they offer is marked as "experimental; use at your own risk".

Beside that BOINC 7.18.1 was never released for any Linux distribution.
Instead it was an Android only release.

You may first upgrade BOINC, then adjust your work buffer size and check your local prefs (especially the allowed RAM).

You have what I can only say is a unique understanding of the meaning of "experimental". If a distro's developers download the source code of an official release, and compile it specifically for their distro, it does not suddenly become "experimental".

That may be, but I have been running these versions of Boinc and VBox since they were installed, without problem until now. Moreover, every other project I'm running (Einstein, Cosmology and Rosetta) is having no problems at all.

There is nothing wrong with my local prefs either. I have been running with these prefs since about 2 weeks after I first began running Boinc last September. Everything has been behaving pretty much the way I want, again until now.

Edit: Well, I am baffled. About an hour ago, a whole bunch of Theory tasks suddenly started arriving. Now I have 20 of them, and all appears to be OK once more.

Making same experience, no flow of Atlas atm, same with Theory (Win11pro).

For Leap 15.4
no official release
an experimental 7.0.8
a couple of community packages (these are not official)

For Leap 15.4
no official release
an experimental 7.22.0

Unsupported distributions
"The following distributions are not officially supported. Use these packages at your own risk."
7.18.1


"experimental" and "Unsupported ..." are terms used by the OpenSUSE website.
Looks like my "unique understanding" is not really unique.



As for BOINC 7.18.1 I suggest to start reading here:

Did you notice the Tumbleweed boinc package, ver 7.22, marked "Official"? It's in the official openSUSE repos, obviously, and it wouldn't be there unless it was an official release.
The same version can be found in the repos at https://download.opensuse.org/repositories/network/ for both Leap 15.4 and 15.5, as well as SLE 15. I think that makes these official as well.

As far as 7.18 is concerned, I know what Boinc says, and I also know that that version, which is in the main installation repository for Leap 15.4 (and hence is necessarily an official openSUSE release), does work in Linux, and has been working here, since I installed it last Sept when I first began running Boinc projects.

The "experimental" stuff is all restricted to the developers' personal workspaces, where they are free to do what they want to get something to compile. Nothing gets out into the repos on download.opensuse.org unless it's been properly vetted and tested, and is known to be stable in a typical running system. The bottom line is simple: if I can find something in an SLE repository, it must be an official version (care to take a guess why?).
