Tasks exited with zero status but no 'finished' file

computing always restarts while notebook goes to sleep
only world community grid does this, other projects (einstein, malaria, seti, predictor) continues after after waking up

BOINC 5.10.13 messages:
Task lf319_00003_7 exited with zero status but no 'finished' file
Restarting task lf319_00003_7 using hpf2 version 518
Task faah2041_d235n850_x2AZC_02_0 exited with zero status but no 'finished' file
Restarting task faah2041_d235n850_x2AZC_02_0 using faah version 528

sorry about my English

Re: Tasks exited with zero status but no 'finished' file

roxton,

You are saying your jobs restart at 0:00:00 CPU time in the Tasks tab of BOINCmgr, for the 'restart' message is a bit misleading? Can you please post the complete messages including timestamps from about 5 before to about 5 after so we can see the sequence. Also, does your laptop go into sleep mode by itself (scheduled), or are you doing this manually?

Computers without stable timekeeping suffer often from this behavior, which mostly only leads to loss of computing time between the last checkpoint and when you put the PC in hibernation (zero power use) or stand-by (some power use) status. Why WCG (and i know at least CPDN and Rosetta do this too) and not your other projects is the dependency on timekeeping which BOINC verifies every second. If it sees only a fraction of a second backward movement due e.g. the internet auto time synchronization, the process assumes it missed a time step and restarts (actually 'resumes') from the last checkpoint it knows things were still okay.

Since you have 5.10.13 will you please create or edit with notepad a little textfile called cc_config.xml. The bolded line will make your message log print the actual checkpoints.
<cc_config>
<log_flags>
<checkpoint_debug>1</checkpoint_debug>
<file_xfer>1</file_xfer>
<sched_ops>1</sched_ops>
<task>1</task>
</log_flags>
<options>
</options>
</cc_config>
After, go to the advanced menu and do "Read Config File". After 30 minutes or so depending on computer speed, will the first checkpoint entry appear. Only after reaching a checkpoint, should a restart not happen from 0:00:00 CPU time in the Tasks tab of BOINCmgr.

For a more extensive explanation of the checkpointing, visit the Start Here forum FAQ: http://www.worldcommunitygrid.org/forums/wcg/viewthread?thread=11332

For an extensive guide on how best to 'hibernate' your computer, visit the Start Here forum FAQ: http://www.worldcommunitygrid.org/forums/wcg/viewthread?thread=8583#69135 . It assumes you have Windows XP, but should work for other Windows versions too.

thanks

nelsoc, can you please move this thread to BOINC support forum

Re: Tasks exited with zero status but no 'finished' file

I may have a reason for his problems. My laptop is running Vista. Whenever I shut down and restarted the laptop, boinc would start a new WU and send the partially crunched one as finished. I learned that I had to close boinc first before shutting down windows. Vista shuts down too fast for boinc to save its work. When a laptop Hibernates, it shuts down windows. When it sleeps, it saves the current programs as is before putting the computer in sleep mode. This sleep still uses power while hibernation uses none, but your programs are saved in memory. If his laptop is set to hibernate instead of sleep, it is shutting down Vista and causing errors in boinc. I set my laptop setting for sleep instead of hibernate, and close boinc before shutting down the computer. I have not had this problem since.
