workunitId=510953719
MCM1_0171641_5005 Status Sent Time Return Time CPU Claimed/GrantedThat was 9 days ago. As of now, still "Waiting to be sent". This workunit app is wcgrid_mcm1_map_7.41_windows_x86_64 running on Linux with WineHQ software. For me, I just have wine-binfmt installed, and a native Linux boinc with alt_platform windows_x86_64. The computer is still mostly linux app. My error was "wine: unable to create wineserver tmpdir", turns out wine software didn't like being run as a Linux service. When I stop service and manually run boinc client, it works. cd /var/lib/boinc-client; sudo su -l boinc -s /usr/bin/boinc & Successfully completed 2 more windows task. Windows app on Linux, when it works, is just as fast as native Linux app. Is this windows tasks on Linux system too strict, it got stuck? Can this windows task resend to actual windows computer to validate? |

Resends run on the same platform as the original.
Hopefully by now it's been validated. |

Hopefully by now it's been validated. https://www.worldcommunitygrid.org/ms/device/...s.do?workunitId=510953719 Over 1 month ago, and it is still "Waiting to be sent". This work unit is probably stuck. |

Maybe it is stuck. One thing I just noticed is under runtime it is showing 0.00 hours, so perhaps a bad work unit

in my former reply, I mentioned it was not accessed to Internet. I had also the mention that I was connected. It was also mentioned that WCG had not enough place. I enhanced the place available.

I currently have four of these. The elapsed time continues to increase, but the progress percentage is definitely frozen. One reaction and two and a half questions:
(1) Such bugs cast doubt on the results. (2) Do I get any credit for the computational work wasted by someone else's mistake? (3) If there is no credit to be earned, when should I have aborted the tasks? Or will I get appropriate extra credit if I just let the server kill the tasks when they run past their deadlines? (Three today and one tomorrow.) |

What happens if you re-boot the PC?

First of all, I misinterpreted the "stuck waiting to be sent", which is a different kind of problem. I haven't seen any cases of those that lasted more than a few hours recently.
However your reply about rebooting is somewhere close to the root of the problem. That actually happened a couple of days ago, and the stuck tasks did continue. I didn't check enough to be sure, but the last time I looked all four of them had moved past the stuck point and three of them were about to finish. Just now I noticed 4 more MCM tasks that were also stuck without apparent progress. This time I just shut down BOINC (both the manager and the running tasks), and when I restarted BOINC the four stuck MCM tasks seemed to be in more normal conditions. All four of them are definitely making progress. I'll keep an eye on them to see what's going on |
