I have a host with Win7, DualCore CPU. On that host are running two virtual machines with winXP. Each machine has boinc and only working an the clean energy probject phase 2.
In machine 1 everything works fine. On machine 2 the first work unit was computed fine. Then it beginn computing from the beginning and telling me it exited with zero but no success file or so. The first work unit I canceled. Got a new one, same problem. I reset the project. Error is still there. I detached from world community grid and connected again. Error still there. Wheres the problem? In virtual machine one everything works fine and also worked fine in machine two for the first work unit. Thanks for help. |

Hello Strom_umsonst,
I am puzzled. I probably can not help, but I think you should give some more information, hoping that some other member can help. First, just what software are you using to create 2 virtual machines? Second, please post the start of the Messages tab on virtual machine #2 to show what BOINC thinks its environment is. Third, you should compare this posted list of messages with the Messages tab on virtual machine #1. There should not be any significant difference. Fourth, check that both virtual machines show the correct date and time, since BOINC is very sensitive to this. Lawrence |

I'm getting a similar errors on repeatedly on HFCC e.g.

Hello jfpz,
exited with zero status but no 'finished' file This is a common warning message that should be ignored unless your work unit starts erroring out. There is a FAQ in Start Here that lists a large number of factors that can cause this warning message to print. Personally, I wish that it would not print by default but only if the user requested for the warning to be printed. Lawrence |

exist with zero status is normal
----------------------------------------all systems have that every once and a while. It usually causes no problems that I am aware of. Sekerob has replied about it many times, saying causes are like os updates, ....  |

When this error is normal, why does the workunit start at the beginning? So there is a lot of CPU time wasted for nothing.
I use VirtualBox for my virtual machines. Date and Time is in sync with the host. The Boinc messages I'll post later when both machines are running again. |

I don't know if this is the same thing, but when I have problems with BOINC, stopping and starting BOINC does not help. If I reboot, all information in memory is cleared and the BOINC problems seem to disappear. That is what I have experienced.
----------------------------------------Edit for additional information: I decided to review further the WUs in Inconclusive Status. In both cases, my execution time was over 8 hours and my wingman's execution time 1.86 hours in one case. I displayed my wingman's processing for the 1.86 hour case and see [04:03:34] Starting job 10,CPU time has been restored to 6135.140625. Application exited with RC = 0x3 [04:09:58] Finished Job #10 [04:09:58] Starting job 11,CPU time has been restored to 6507.671875. [04:09:58] Skipping Job #11 [04:09:58] Starting job 12,CPU time has been restored to 6507.671875. Application exited with RC = 0x80 [04:13:25] Finished Job #12 [04:13:25] Starting job 13,CPU time has been restored to 6705.593750. [04:13:25] Skipping Job #13 [04:13:25] Starting job 14,CPU time has been restored to 6705.593750. [04:13:25] Skipping Job #14 [04:13:25] Starting job 15,CPU time has been restored to 6705.593750. [04:13:25] Skipping Job #15 04:13:31 (9692): called boinc_finish The other WU had one job exiting with an RC that caused the remaining jobs to be skipped. I think this is why these WUs are Inconclusive. [Edit 2 times, last edit by Former Member at Dec 19, 2010 7:49:50 AM] |

Thanks for the reply Lawrence, like others it is frustrating to see this error message on multiple results totaling hundreds of hours of work. It wastes my time and wastes time that could be put into meaningful processing. Will read the FAQ and see if it contains a fix for HFCC

When this error is normal, why does the workunit start at the beginning? So there is a lot of CPU time wasted for nothing. This project has some very long intervals between checkpoints. Leave applications in memory will address this problem on a normal machine. As for the virtual machine, I can't begin to say how it affects it other than to say anytime the work unit is unloaded from memory it will revert to the previous check point. If it hasn't run a two to three hours from beginning, this checkpoint will be the start of the work unit.  Distributed computing volunteer since September 27, 2000 |

I think this may be host name related; Boinc is seeing both systems as being the same and resetting one. Can you first confirm that you are not using BAM or that your system is restarting (due to automatic updates or a system failure)?
