Hello,
I use several computers for Boinc. But I have issues with all my computers and all my projects to get work.
First I removed the account manager and it seemed to help a little.
Now I have this messages:

There are CPU and GPU tasks available for my PC's.
I found out that when request CPU has 1.00 sec as value, the request is done. Else no request is done. How is this happening?

Is the crucial line.
If under options>event log options you enable work fetch debug it should tell you why it is not requesting tasks.

20GB disk space is I think a bit on the low side for allowing 4 Einstein tasks to run at once. I would be tempted to up it to 50 to give some head room. What other projects are you running if any?

You have a 6 day queue which is massive (mine is 0.1 + 0.05 for example) but the zero seconds required suggests that it’s full.

If not then try setting <sched_op_debug> on in the event log options for more details.

The work_fetch_debug is already turned on. I have 11 projects in the manager. 6 of them have work. A long time ago I did the same and then every hour it switched to other projects.

I just enabled the sched_op_debug. I paused the projects which have running tasks. Before it would fetch new tasks from projects which are allowed to run. There are no running GPU tasks at all.

Are they the debug version of the flags? I thought debug gave more info than that.

Yes they are.
It has to be some issue with the following line. When it says 1.00 sec instead of 0.00 sec, the request will be done and work will be fetched.

[work_fetch] request: CPU (0.00 sec, 0.00 inst) NVIDIA GPU (0.00 sec, 0.00 inst)
