One of my computers spent 56 hours on 7 work units that were issued to it on 11/14. If I understand this "work unit status" page (below) correctly, 2 peers processed the same work unit in under 4 hours (mine being the "Error" one below). This computer has two quad core Xeon 5410 processors with 4 GB memory running 32 bit RHEL 5.2 using BOINC 6.2.15. It would appear that the problem was on my end, but I have no idea what would have caused it.

Hi,
----------------------------------------first look in the Result Status page and click on the error log. Probably a exceeded cpu time???? Please copy paste in your next post. BOINC 6.2.15 ? What OS? Was the system recently booted? If so can you please go to the beginning of the client message log and also post the top 30 lines of startup information. This will give us all the base info needed to understand your sytem better.

Sorry that I didn't explicitly state it earlier, but yes, they exceeded the CPU time limit:

Well, I don't like the mid job
----------------------------------------Unrecognized XML in parse_init_data_file: computation_deadline Skipping: 1259058234.000000 Anything in the stdoutdae.txt log file indicating job resumes? I've had several jobs hung on newly installed W7-64 bit post BOINC manager hangs, amongst a RICE job which showed near the end similar start all over log entries: Result Name: R00433_ 6fdfb9e90643b6d8e2f46844db78be6f_ 03_ 008_ 7-- <core_client_version>6.10.18</core_client_version> ... wcg_seed 41234051 Unrecognized XML in parse_init_data_file: hostid Skipping: 1112084 Skipping: /hostid Unrecognized XML in parse_init_data_file: starting_elapsed_time Skipping: 10672.325539 Skipping: /starting_elapsed_time Unrecognized XML in parse_init_data_file: computation_deadline Skipping: 1259348301.000000 Skipping: /computation_deadline wcg_seed 1054116059 running time: 10160.423306 wcg_seed 493042590 Unrecognized XML in parse_init_data_file: hostid Skipping: 1112084 Skipping: /hostid Unrecognized XML in parse_init_data_file: starting_elapsed_time Skipping: 10672.325539 Skipping: /starting_elapsed_time Unrecognized XML in parse_init_data_file: computation_deadline Skipping: 1259348301.000000 Skipping: /computation_deadline wcg_seed 362329819 running time: 10162.170518 ... To my surprise full seeds were counted and sumptuous credit granted (yes RICE does more on 64 bits). In past only those seeds after these intermissions were considered, so maybe code was improved? Maybe knreed will comment. Learning from past, I thought I'd caught all the usual security settings and exceptions, not counting on the 6.10.18 client manager itself being able to hang itself and cause sufficient interruption for the jobs to shake.

It looks like you experienced an issue that it isn't clear what happened. However, after looking at your results since then the issue appears to have been corrected and you are no longer getting errors. Let us know if the error returns.

Are all WU's crunched twice? |
