    Me too.

    Thanks for the informative updates, Gary. I guess I'll just have to stop checking my status for a while and find something useful to do. ;-)

    Cheers;

    Peter.

      Sorry for late reply, been quite busy last days.

      Could anyone affected please post or send me his file sched_reply_einstein.phys.uwm.edu.xml from the BOINC directory?

        I already posted the important bit a few messages earlier :-).

        Here is a bigger snippet. It contains the specification which is truncated part way through the block and with the following block joined in at the point of truncation. This is a task that is failing to be sent to one of my hosts. Every example I've looked at so far looks pretty much the same - identical point where garbage chars start. Make sure you scroll to the right to see the garbage at the end of the string.

        EDIT: I've highlighted the string in red - color tags don't work inside code blocks so I had to break the snippet into 3 code blocks to get the important one to show in red.

          One of my hosts is getting the following error message when trying to report a result.

          7/21/2010 10:11:35 AM [error] Can't parse workunit in scheduler reply: unexpected XML tag or syntax

          Looking at the workunit h1_1105.75_S5R4__737_S5GC1a I see that some host has already finished this workunit successful, but with a pretty old Core Client (5.4.11). What Client versions does this error happen on?

          Quote:
          I googled around, and found that Primegrid had a similar problem. They ended up downgrading the scheduler to fix it. Did Einstein recently upgrade to a newer scheduler and get the same bug?

          We didn't change the scheduler recently.

          The problem could have been there for a while: The workunit generator of GC1 shifts from lower (analysis) frequencies to higher ones. The higher the frequency of a task, the more data is required, which means more data files and thus longer command lines. It's just now that our GC1 workunits hit a buffer limit.

            Thanks, Gary.

            What I was missing is the name (or ID) of the workunit to which this command line belonged, to track it through the system.

            We are surely hitting a buffer limit, but my suspicion is that this limit is actually in the Core Client, not on the server side.

            Would anyone try a downgrade?

              The machines I'm seeing this on are 6.10.56 but I've just also seen it on a 6.2.15 linux host. That's pretty old anyway so how far back do we need to go?

              I used to use 5.10.45 but that version (although supposedly stable) had a pretty serious bug that caused me to lose many hundreds of tasks during a couple of server outages. I'm reluctant to go back there - it was the end of version 5 as I recall. Maybe all version 6 BOINCs will have this so ... any suggestions on what version you want me to try?

                Yep, that's what I'm wondering, too.

                No. I wrote to BOINC developers, but they won't get up earlier than 6h from now.

                If this is a problem to be fixed in the client, it will take some time to do so, and all 6.x Clients would probably have this.

                  I downgraded a machine to 5.10.45 and the exact same problem still shows up on that version as well :-(.

                  EDIT:
                  I've been running tasks for frequencies between 1139.65 and 1141.30 on a substantial group of machines for around a month now. Thousands of tasks have been done without any issues until now.

                  Logic says that it can't be the BOINC client or else why have I been able to work at these high frequencies for so long?

                  Unfortunately. logic also says that it's likely that something has changed in how new tasks for these frequencies are being generated.

                  I've found a 5.8.13 BOINC and installed it. Still exactly the same problem with exactly the same sched_reply.

                    Please update the project (possibly needs a project reset to work).

                      I've just reinstalled 6.10.58 on the machine I'd taken back to 5.8.13. After restarting BOINC and trying an update, the same error messages are reported.

                      I have a bunch of machines with work in progress and I'm not prepared to lose what has been done over the period this problem has been around. there'd be more than 100 tasks involved. Sure, most have probably already been reported even though each client thinks to the contrary. Still, there's the work in progress and I don't particularly want to junk my caches.

                      Is there a manual edit to the state file that could achieve the same result as a full reset?

                      Cheers,
                      Gary.
