    Yeah but he wasn’t originally using project max concurrent so that’s likely not the problem anyway. 
     

    Neal, with your cache set to 0.05 days, and you manually reducing the cache to some small level, what does BOINC request for work? Post the event log entries when Einstein is doing a schedule request

      I think that the <max_concurrent> in the app section of app_config.xml will have the same effect.

        No. 7.16.20 was released in October.  The patch for project max concurrent didn't get merged until December.

          I'm already running 7.16.20, since the end of February.

            7.16.20 doesn't have the fix for project max concurrent. Will have to wait some more for a newer build that incorporates the fix.

            Or build the client yourself from the current Master branch which incorporates the fix.

              I don't know if these logs are going to help. They only go back to early this morning, and the tasks had reached a steady state by then, so the number was no longer growing. I also set the resource share to 0 at some point. I can't recall when.

              In this sample, it seems to be receiving about the same number that it's sending:

              At some point this morning I set the project as "No new work", so there is no significance to the logs after that.

              By the way, what do you suggest I do with all of the excess tasks that have accumulated? Should I abort them and get fresh ones, or work through the backlog until they are about to reach the deadline? Do they lose value while sitting in the queue for days?

              Thanks.

              PS. I had looked in the logs when it was still growing, and here's what I saw it doing: Every time it sent any completed tasks, it would download a larger number, like maybe 2x. So it grew a little each on each update. It finally stopped when it had around 1000. There is probably some significance to the number 1000.

              you don't have to abort them.

                you don't have to abort them. you can just hold on to them and crunch them. you will complete them all before deadline easily if you're running 24/7. they do not lose value as long as you submit them.

                  Yes, the client and project max allowed is 1000 tasks. That is the default BOINC client and server limit unless overridden by the project admins or running a custom client.

                    Thanks. I think that with Rosetta@Home, there were people waiting for the results, so the turnaround time was important.

                      That makes a lot of sense.
