Well must be going wrong somewhere, I still have the download failures with the above error code and this in the message box.
18/08/2011 22:14:57 World Community Grid Started download of c4cw.target04.water-filled-filtered 18/08/2011 22:15:03 World Community Grid Finished download of c4cw.target04.water-filled-filtered 18/08/2011 22:15:03 World Community Grid [error] File c4cw.target04.water-filled-filtered has wrong size: expected 12642142, got 3153468 18/08/2011 22:15:03 World Community Grid [error] Checksum or signature error for c4cw.target04.water-filled-filtered I detached and reattached with no success. Upgraded from boinc manager 6.10.58 to 6.12.33, reattached and still the same download error. Strange because my laptop running boinc 6.10.58, successfully downloads the units. Can anyone see where I am going wrong? |

Been reporting to ask a tech to look in. Detaching / reattaching would normally remove the problematic files, but project reset would do too. What you can do is detach WCG, delete ALL subdir content of www.worldcommunitygrid.org, path something like C:\ProgramData\BOINC\projects\www.worldcommunitygrid.org boot machine, attach WCG again, then see if things stabilize.

Thanks for your help.
I already tried deleting the boinc data files. I actually removed boinc manager completely and then deleted the whole boinc data folder, before reinstalling boinc and attaching to WCG. However the downloads failed again. |

It's the boot bit in the run down I gave. That often works wonders, not always, but in despair. Why only C4CW now? 65,000 question for me.

Been reporting to ask a tech to look in. Detaching / reattaching would normally remove the problematic files, but project reset would do too. A reset will not remove <sticky/> files, and c4cw.target04.water-filled-filtered is a <sticky/> file.  "I make so many mistakes. But then just think of all the mistakes I don't make, although I might." |

That's a serious hmmm, and makes it harder to return to sanity. Yes I knew that some files would not go away, but an actual operationally required file not going... fail to see the rational.

@SekeRob
----------------------------------------Why only C4CW now? Some months ago (May 2011), I experienced serious problems with C4CW on a Q6600 running WinXP Pro SP3, errored WUs, unability to report WUs, spontaneous project reset Now only one host - Q9450, Win XP Pro SP3 - is crunching very reliably for C4CW. I was not able to understand what happened on the Q6600. At the same time, for C4CW, I noticed poor performance on the both Phenom II x6 with Ubuntu 10.04 x64. Cheers, Yves |

And again, as I switched another machine from FAAH to C4CW, it gave back 15 errors of the same kind.
The machine previously discussed got better, after >30 errors. It must be a temporary issue, but again if someone could look at it, I am sure I am not the only one. Thanks |

The only suggestion I have is regular restarts, and it's not a good one.
----------------------------------------I have a hopefully interesting perspective for the techs WRT this kind of problem, it's relative to that of the cruncher, and a view which is apparently indicative to WCG's approach. To the tech, you see but a relatively few errors percentage wise - not worth dealing with. To the affected cruncher, you see the sky falling in, on your efforts - the world is at an end and you personally need emergency help ASAP. On more that one occasion I have had systems continuously fail certain project tasks (not recently), and to the extent that I stopped getting new work on the effected systems. I think the WCG needs a backup strategy to support crunchers that find themselves in this predicament. I suggest an emergency WCG profile be used in such situations so that members crunch other favorite projects, and failing that All normal projects, to reduce such problems and outages. GL - imposed -> used :) [Edit 1 times, last edit by skgiven at Aug 21, 2011 2:04:27 PM] |

May well work and is one of the design goals already, but what if the heavens come down profile has only 1 science selected and not the ''if there is no work [that my computer can successfully process], send me something else."? Imposing then to send something else; Doubtful.
