I've encountered following problem:
2007-09-30 17:21:31|PrimeGrid|Task llrCUL_7871659_0 exited with zero status but no 'finished' file
2007-09-30 17:21:31|PrimeGrid|If this happens repeatedly you may need to reset the project.
2007-09-30 17:21:33|PrimeGrid|Restarting task llrCUL_7871659_0 using llrCUL version 507
Tried reseting the project, but it's not helping.
That's what I've found in stderr.txt:
BOINC LLR 5.07 wrapper: starting
Major OS version: 5; Minor OS version: 1
Changed thread_handle to 116 (2388)
pid: 132, thr: 116
// Nothing interesting here...
No heartbeat from core client for 31 sec - exiting
Seem that either client's stuck in infinite loop or watchdog is overreactive :)
BTW: I'm running Win XP + BOINC Manager 5.10.13
