skgiven,
I think I was wrong... I'm about to check it once again, but it seems that after restart the tasks return about two dozens of valid results and then begin to crash. The same is happening with version 6.10.58. SekeRob, As for MySQL, I just stopped it on this server. Actually, it was one of the reasons why I deployed boinc there — I just wanted the server to do something :) |

Suggest to run, after another boot, a mix of HCC/HCMD2/C4CW and see if this postpones the error development.
Don't know if there are other members who run 16 core machines (real or hyperthreaded cores incl.?) with C4CW only, presumably on 64 bit and the success rate. Let us know. |

I do run a mix of c4cw, Clean energy and Cure for cancer tasks. Sorry for not mentioning that before. The other projects work fine. Besides, the server works for climateprediction.net, but they have no tasks now.
The server has two quad-core CPUs with hyperthreading. I've joined SIMAP today. Can't find results stats on their web site, but I hope there'll be enough info in the logs to find out if their WUs complete correctly. |

SIMAP has a http://boincsimap.org/boincsimap/batchmonitor.php and on the Your Account there is somewhat down the link to Tasks view.
Top will show the science app that's running where the suffix indicates if it's a 32 or 64 bit version. The initial download also shows the version/bit size, for example: 1764 boincsimap 02-06-2011 08:48 Started download of simap_5.12_windows_x86_64.exe --//-- |

It looks fine and you're running: BOINCSIMAP simap application 5.10 x86_64-pc-linux-gnu Your valid SIMAP's: http://boincsimap.org/boincsimap/results.php?...;show_names=0&state=3 Your pending SIMAP's waiting for wingmen: http://boincsimap.org/boincsimap/results.php?...;show_names=0&state=2 |

I've downgraded boinc-client back to 6.10.17. Thus far, 31 BOINCSIMAP tasks were validated. I think we can safely assume that SIMAP works fine. Reattaching WCG again.

Most curious, I've put a note out to the techs asking to look in. SIMAP is not the lightest of computations, certainly it causes me quad CPU to always warm up a tad more.

Still the same. C4CW remains the only task that regularly returns errors. After restart, some tasks complete successfully, but soon they begin to segfault.
----------------------------------------I tried to debug the tasks using 'strace' tool, but the results looked more like I was debugging the controlling task of boinc-client then the calculation itself. Is there a way to debug the WUs? Or to increase logging level for them? SekeRob, glad you liked these two blogs :). Unfortunately, I had little time to update them in the last months.

Did you try just running C4CW (no other task types), to eliminate the possibility that other tasks are causing this (holding onto memory space, or using memory area assigned to another thread, for example)? You would need to do a restart after present tasks complete to rule out any interference by existing tasks or other tasks that have already run.

No, I didn't. Will try, thank you. It'll take time, as usual :)
