I've been getting the following error all morning. I don't understand it completely, but it looks like it's trying to download a result that I have already received and have as of now completed and uploaded the finished files for. Here's my log information: LHC@home - 2005-03-02 10:17:01 - Requesting 8525 seconds of work LHC@home - 2005-03-02 10:17:01 - Requesting 8525 seconds of work LHC@home - 2005-03-02 10:17:08 - Scheduler RPC to http://lhcathome-sched1.cern.ch/scheduler/cgi succeeded LHC@home - 2005-03-02 10:17:08 - Already have result v64lhc92-37s8_10575_1_sixvf_1085_5 LHC@home - 2005-03-02 10:17:08 - Got ack for result (null), can't find LHC@home - 2005-03-02 10:17:08 - No work from project LHC@home - 2005-03-02 10:17:08 - Deferring communication with project for 48 minutes and 14 seconds I can confirm that the result mentioned above in the log entries is the wu that I just finished computing and returned to the server. However, I can no longer download any new work or report the finished wus from my BOINC client. I can't seem to find any information on this, but think I vaguely remember something similar to this happening on another project (maybe PP@H?).

I just wanted to add that this isn't an isolated incident -- I'm getting a similar message: LHC@home - 2005-03-02 15:42:37 - Sending request to scheduler: http://lhcathome-sched1.cern.ch/scheduler/cgi LHC@home - 2005-03-02 15:42:41 - Scheduler RPC to http://lhcathome-sched1.cern.ch/scheduler/cgi succeeded LHC@home - 2005-03-02 15:42:41 - Already have result v64boince6ib1-23s14_16660_1_sixvf_7724_3 LHC@home - 2005-03-02 15:42:41 - Got ack for result (null), can't find I have seven WUs on my machine, two finished, one in progress, and the rest ready to run.

I had this problem a while back, and I thought I was the only one. Someone is also having it on Predictor. old thread: http://lhcathome.cern.ch/forum_thread.php?id=1176 Predictor thread: http://predictor.scripps.edu/forum_thread.php?id=1335 The cure (for me, anyway) was to detach/reattach. |

@Genes > The cure (for me, anyway) was to detach/reattach. Thanks for your help, but this time the detach/reattach didn't work. However, it did change my status because now I'm getting signature verification errors on the sixtrack client executable file. I'm going to dig around a little bit for an answer and I'll update if I find a solution. -EDIT- I've looked around and didn't notice anything that seemed helpful on the checksum errors... Detached and reattached twice now with the same result - checksum error on the download of the sixtrack executable. I'm getting the following when the client tries to reattach to the server: LHC@home - 2005-03-03 02:33:28 - Requesting 8527 seconds of work LHC@home - 2005-03-03 02:33:32 - Sending request to scheduler: http://lhcathome-sched1.cern.ch/scheduler/cgi LHC@home - 2005-03-03 02:33:35 - Scheduler RPC to http://lhcathome-sched1.cern.ch/scheduler/cgi succeeded LHC@home - 2005-03-03 02:33:35 - Already have result v64lhc92-37s8_10575_1_sixvf_1085_5 LHC@home - 2005-03-03 02:33:35 - Got ack for result (null), can't find LHC@home - 2005-03-03 02:33:35 - No work from project LHC@home - 2005-03-03 02:33:35 - Deferring communication with project for 1 minutes and 0 seconds LHC@home - 2005-03-03 02:33:35 - Started download of sixtrack_4.64_windows_intelx86.exe LHC@home - 2005-03-03 02:33:50 - Finished download of sixtrack_4.64_windows_intelx86.exe LHC@home - 2005-03-03 02:33:50 - Throughput 188022 bytes/sec LHC@home - 2005-03-03 02:33:50 - signature verification error for sixtrack_4.64_windows_intelx86.exe LHC@home - 2005-03-03 02:33:50 - Checksum or signature error for sixtrack_4.64_windows_intelx86.exe Any help is appreciated! -EDIT- Regards, Clint www.clintcollins.org - spouting off at the speed of site |

This is obviously not the best solution, but it worked in that I was able to d/l fresh WUs. I deleted the file it said it already had the result for, then closed and reopened BOINC. I updated, and received new WUs. Hate to possibly muck up another result (though isn't that why BOINC is redundant?) but this way I at least crunched several more WUs that I wouldn't have gotten otherwise. <img src="http://boinc.mundayweb.com/one/stats.php?userID=497&trans=off"> |

My error has evolved... While I was out my client reconnected to the server and apparently downloaded the executable correctly without the signature verification error. However, I now cannot download the logo_back_1.01_.tga file correctly. I'm getting the "wrong size" (checksum?) error, so I suspended network activity to keep from flooding out a bunch of worthless d/l requests for the file which was repeating over and over. Here's the new errors from my log: LHC@home - 2005-03-03 23:15:47 - Started download of logo_back_1.01_.tga LHC@home - 2005-03-03 23:15:54 - Finished download of logo_back_1.01_.tga LHC@home - 2005-03-03 23:15:54 - Throughput 32150 bytes/sec LHC@home - 2005-03-03 23:15:54 - Giving up on download of logo_back_1.01_.tga: Downloaded file had wrong size: expected 2691072, got 210483 LHC@home - 2005-03-03 23:15:54 - Started download of logo_back_1.01_.tga LHC@home - 2005-03-03 23:16:02 - Finished download of logo_back_1.01_.tga LHC@home - 2005-03-03 23:16:02 - Throughput 29032 bytes/sec LHC@home - 2005-03-03 23:16:02 - Giving up on download of logo_back_1.01_.tga: Downloaded file had wrong size: expected 2691072, got 210483 LHC@home - 2005-03-03 23:16:02 - Started download of logo_back_1.01_.tga --- - 2005-03-03 23:16:04 - Suspending network activity - user request This pattern repeated for quite a long time until I got in and shut down communication. Any help on this would be appreciated. I haven't been able to crunch LHC workunits for over a day now. Regards, Clint www.clintcollins.org - spouting off at the speed of site |

> Any help is appreciated! > -EDIT- Clint, try this -detach from LHC -exit the boinc client. -go into the boinc\\projects folder if still present, delete the full lhcathome.cern.ch -go into the boinc\\slots folder LHC attached only--> delete all 0,1,2,3,4 not only LHC Attached, look into 0,1,2,3,4 and delete all entries related to LHC. -now restart the boinc client, it should be empty now and attach to the project. good luck |
