We are looking into the issue along with the researchers. One thing to note is that it appears as though the problem may be related to restoring from a checkpoint. If a user is having a high number of errors with CEP and has the memory resources available to leave the application in memory this may work as a temporary workaround while we investigate the errors.
Thanks, armstrdj |

One thing to note is that it appears as though the problem may be related to restoring from a checkpoint. Sounds very likely to me. I did some troubleshooting on my machines that were throwing errors in CEP, and it turns out that they were actually crashing and rebooting many times a day. I have BOINC on auto-start and these machines have no graphics so I didn't catch this problem earlier. When I would check in on them via BOINCview or remote desktop, all appeared to be working fine. It was only by reading the message log in BOINCview that I could see the BOINC startup sequence repeating randomly. The workunits likely errored after the reboot and they had no checkpoint to restore. Anyways, I bumped the core volteage on each machine by 0.01v(2 notches in BIOS) and they've been running 48 hours now with no errored WU's or crashes.  |

I had my first error 29 yesterday afternoon, and it could confirm your theory about restoring from a checkpoint.
----------------------------------------It happened about one minute after my quad had restarted 4 CEP tasks after a fresh boot. Only one of the four tasks failed with no message in the message log and only this line "process exited with code 29 (0x1d, -227)" in the Result Log. This machine usually shows errors only when WUs are wrong, which has not happened for many weeks. This was with Boinc 6.2.18 under Ubuntu 9.04 64-bit, and obviously no antivirus program. Regarding the fresh boot and thus restarting tasks I do it about once a day without any trouble since I run this machine alternatively under Ubuntu 64 and XP 32 every day. |

Jean, do you use the delay on system restart config setting? Had a different, surely unrelated one yesterday around the time of a resume, but no error message of meaning.

Jean, do you use the delay on system restart config setting? No, but with this config without bells and whistles, more than one minute after Boinc started the Ubuntu boot has already completed.  (even in XP 32 I have reduced it to 60 seconds). |

We are removing any jobs that end with {0h, 0i, 0j, 0k, 12, 13, 14, 15} as these appear to be causing a larger number of error 29. These work unit simulations push the temperature higher than the others causing the issue to appear more frequently. We are aborting both active work units with this identifier and future work units with these identifiers.
Thank you for your patience as we continue to work through this. -Uplinger |

Or are they withdrawn completely (leaving us with less work remaining for the project)? Greetings Thorsten |

Yesterday WU E000902_117C_009q0670f had an exception error at 92%. I restarted it (after backup) and it completed. But this was done within three minutes, i.e. it needed THREE minutes to run from 92% to 100% (athlon with an average completion time of 14 hours):
10-Aug-2009 15:33:34 [World Community Grid] Restarting task E000902_117C_009q0670f_0 using cep1 version 632 10-Aug-2009 15:36:48 [World Community Grid] Computation for task E000902_117C_009q0670f_0 finished Then it reported (all result files were present). Was pv. AND BECAME VALID!! So why can't all WUs terminate with 92% if that is sufficient for becoming valid? Or is something wrong with the validator? Matthias |

Got other again...
