Again, I am seeing WuProp killing active or suspended (in memory/disk) tasks that have or have not checkpointed when it completes and reports a WuProp task or when it communicates with the WuProp servers... I lost a cumulative of over 40 hours on the new QMC tasks that do not checkpoint for many hours and had to decide between running WuProp or QMC on the affected PC's... Only seems to happen if the computers clock is off by more than a few seconds from what WuProp servers time is when the WuProp program "phones home".

This has been a known problem## with the WuProp task for some time now and needs to be fixed. ##See Message boards : Number crunching : Problem with Linux locking up machines??? --- ... --- specifically message #1131

This is not WuProp fault, this is long existed BOINC fault. I reported this on 4 Mar 2008 (and maybe there exist older reports): Computer Clock back stops BOINC: http://setiathome.berkeley.edu/forum_thread.php?id=45717 If "the computers clock is off by more than a few seconds" (more precisely 'if the computers clock is off more than 30 seconds') and then for whatever reason the computers clock returns (synchronizes) to the proper current time BOINC stops all apps and restarts them after the 'missing' period of time has passed. (search in Google for: "No heartbeat from core client for 31 sec - exiting") So "tasks that have not checkpointed" lose all progress. (tasks that have checkpointed restart from the last checkpoint)   - ALF - "Find out what you don't do well ..... then don't do it!" :) |

I've had 3 errors in the last few days (all on the same system). I added a couple of GPU's (to test GPU detection): http://wuprop.boinc-af.org/result.php?resultid=30850512 Name wu_v3_1374391616_297861_0 Workunit 30364010 Created 28 Jul 2013 20:43:51 UTC Sent 28 Jul 2013 20:58:05 UTC Received 28 Jul 2013 21:54:23 UTC Server state Over Outcome Computation error Client state Compute error Exit status -2147483645 (0xffffffff80000003) Computer ID 44207 Report deadline 7 Aug 2013 20:58:05 UTC Run time 780.33 CPU time 0.36 Validate state Invalid Credit 0.00 Application version Data collect version 3 v3.52 (nci) Stderr output <core_client_version>7.2.5</core_client_version> < =sticky tape=

...and another - Each time Windows restarts and when I log on I see a WUProp error! When the application crashes, can you send me a copy of file cache to this e-mail: sebastien[at]statseb[dot]fr
