    Hi there,
    I've been running SETI and ClimatePrediction on linux for some time, and more recently attached the Einstein@home project. While SETI and ClimatePrediction work fine, Einsten@home would not resume normally... In fact, it does 'technically' resume, but it does not compute... Likewise, it does not stop using the usual 1 hour shift so that SETI and ClimatePrediction can't start...

    Now if, when this problem occurs, I break (Ctrl+C) and restart , then Einstein@home restarts fine.

    Below is a copy from the console where I run BOINC. Looking at it, it seems that there is something wrong with the 'deferring communication' thing...

    Any clue ?

      I don't think anything is wrong. The communication is being defered because your machine has no results to report, and the scheduler doesn't want to give you more work (yet) because it's afraid that you might not complete it by the deadline.

      Why do you think your machine is not doing any computing?

        Hi,

        I think there is a problem with einstein version 4.80 under linux. I have the same problem running boinc with seti@home and einstein@home. Before I attached to einstein boinc worked well, but now boinc stops a few times a day switching between the two projects although both projects have work to do. This only happens when einstein@home is running. When I then type 'grep fraction_done client_state.xml' from time to time I don't see any changes anymore until I restart boinc.

        For the first I will switch off the option 'leave in memory' to restart einstein@home more often.

        Alexander

          I can assure you that 3 of my mandrake systems stop computing when it changes from seti back to einstein. It does not occur with absolutely every project change coming back to einstein, but it happens about 90% of the time. Thus far, though, it has never happened with any other project - only when coming back to einstein. My gentoo system changes back and forth with no problem, and one other mandrake system is currently attached only to einstein.

          On my systems that share boinc, I have to constantly ctrl-c and restart after it shifts back to einstein. Shifting from einstein to another project causes no problems at all - only coming back to einstein causes it to stop.

          There are a couple ways that I know it isn't running - first and foremost is that my cpu goes idle when it comes back to einstein. Secondly, there are no updates being made to the fstats files in the project slot, even though boinc reports the project is running - the "date modified" notation in nautilus continues to show the time einstein was last really running, before it went to another project and tried to come back to einstein.

          Beyond that, on my system with 4.23, the work tab in boincmgr shows the status is running, but the cpu time and wu progress never change. (Note that the problem does not only occur in 4.23 - my other systems that do the same thing are running 4.19 - 4.23 only gives one more way of seeing it.) Also, when it shifts back to einstein it simply stays "assigned" to run einstein from that time forward (I assume this is because the debt is not changing, so it never comes time, debt wise, for another project to start back up).

          Below is an excerpt from my log from this morning, with all the seti and pirates futile attempts to get data edited out. As you can see in the log, it switched from einstein to seti at 03:46 then back to einstein at 04:46 - and there it sat until I broke it and restarted it after I got up and saw the cpu usage at 100% idle.

                Any updates on this?

                This bug also occurs in Boinv v4.27 and v4.32.
                I think it is more severe than a simple Annoyance. It prevents my computer from working on more than 1 Boinc project at the same time without me babysitting it.
                When this occurs, einstein resumes eventually after I switch the computer from "Run always" to "Suspend" and back several times.
