Folks,
I'm seeing an issue with a 'stuck' WU. The job is not using any CPU resources and none of the counters in BOINC manager are incrementing. BOINC manager shows the job running with high priority. The job details are: WU Name: faah4081_Ampr_wH_xmd16730_01.dpf BOINC version: 5.10.21 FAAH version: 6.05 O/S: Linux (kernel 2.6.21-6.fc7xen) STDERR for this job is included at the end of this post. Has anyone else seen an issue like this and (if so) do you have any ideas about a possible fix? I'd seen this happen once before (although I'm not sure if the problem was also with FAAH). I had previously tried suspending and re-enabling the WU - but that didn't work for me. Cheers Sean STDERR begins: ************* INFO:[00:22:43] Start AutoGrid... autogrid: autogrid4: Successful Completion. INFO:[00:24:51] End AutoGrid... Beginning AutoDock...

First, check whether BOINC is starved for CPU time. If another process is using most or all CPU time, BOINC will get little or none.
If it is really stalled, try restarting BOINC. If all else fails, consider aborting. |

However I gave the stalled job a kill -HUP and it came back to life. I guess the same result would have been achieved by restarting BOINC as you'd suggested. Anyway problem solved and thanks for your help ! Regards, Sean |

It's this "I had previously tried suspending and re-enabling the WU" that is known not to work. It's necessary to unload the job from memory which is most often achieved by suspend WCG in the project tab for 30 seconds. This kicks the job back to the last checkpoint. Unloading BOINC completely is the next sure thing and forces the issue, but looses any progress after last checkpoint for all jobs in progress.
