Hi, here's an extract from my stderr.txt: 2004-10-18 14:47:22 [LHC@home] Unrecoverable error for result v64lhc1000pronine-41s12_14526.73_1_sixvf_2295_1 (There are no child processes to wait for. (0x80) - exit code 128 (0x80)) Does anybody have idea what this means? The result uploaded to server OK though. The WU calculation took 1h 15 min as they usually take 1h 30 min. Using Boinc 4.13, set up to Seti 66.6% and LHC 33.3%. |

Your computers are hidden so I can't see what OS you are running. Is it by any chance linux? I stopped running LHC on my P3-500 running knoppix because 90% of the work units errored out like that when they were just about to complete. I'm wondering if there is a problem with the linux client. The same setup is doing seti@home work units without incident. On the other hand, my other linux box which is running gentoo does not seem to be having the same problems so I'm not sure what to think. Maybe something about knoppix gives bad mojo? -------------------------------------- A member of The Knights Who Say Ni! My BOINC stats site |

Now my computer should be visible. It is running Windows 2000 SP4. I don't have any Linux systems available. |

Darn! I was hoping for a trend. oh well :) Guess my exit codes are different than yours as well. I think I posted about this in another thread already actually... Ah yes, here it is. 2004-10-15 01:50:45 [LHC@home] Unrecoverable error for result v64lhc1000profour17s12_14518.18_1_sixvf_8194_9 (process exited with code 12 (0xc)) Most of the ones I see right now are code 12. a few are code 240 (0xf0) Maybe the admins could post a list of error codes and what they mean? could help to track down the problem and see if it is a configuration/library/hardware problem on the client machine or maybe a bug in the software. Anyone? :) -------------------------------------- A member of The Knights Who Say Ni! My BOINC stats site |

You might find lists on the Microsoft web site; they come in many flavors. Since is was near the end of the calculation, my guess is that is was some IO error. You seem to have plenty of RAM; what mobo are you using and what is the chipset? |

There may be a trend if it was the Pentium running Linux; the error may have been generated in the math processor of the chip or some IO glitch that it didn't cope with. |

It was the Pentium 3 linux box running knoppix. I had the boinc directory mounted via an SMB share to my windows box so as not to lose work if I had to reboot the knoppix box. (it has no hard drive) I believe I was seeing the same bugs that exist with NFS. See here for details. I decided to just take LHC off of that one for the time being and put it on seti which runs without any problems over a network mount. -------------------------------------- A member of The Knights Who Say Ni!

Ever since the V4.13 BOINC, I'm seeing an increased number of various "Computing Errors" on random Win32 and Linux boxes (SETI and LHC, but luckily not with CPDN). Seems there are some Bugs needed to be fixed. ___________________________________________ <p>Scientific Network : 36200 MHz �� 8204 MB �� 815.0 GB </p> |

I'm running BOINC 4.13 GenuineIntel 997MHz Pentium Microsoft Windows XP Professional Edition, Service Pack 2, (05.01.2600.00) 4 of my last 10 WUs came back with a computation error similar to this: Unrecoverable error for result v64lhc1000prosix-27s10_12551.21_1_sixvf_30583_3 (exit code -1073741819(0xc0000005) 2 of my last 8 SETI workunits generated similar errors. I'm also running the classic version of Climate prediction, and I'm still attached to Predictor, even though they've been out of order for over a month now. Am I doing more harm than good staying on this project? Should I detach? Thanks, Jason > It was the Pentium 3 linux box running knoppix.

I am investigating this problem on my win 98 machine. I think I may found the problem: regionnal settings, clock, date formats, etc. ( so far so good). |
