Hello,
I have one ARP task running for more then 3 days now, and for the last two days it shows 99.000% done. So two days running fullspeed without any progress. What should I do? Abort, and flush 3 days of crunching to /dev/null? Or just wait? Any advice appreciated, thanks Willem Running Linux Mint 19 Tara [4.15.0-115-generic|libc 2.27 (Ubuntu GLIBC 2.27-3ubuntu1.2)] |

Hi,
----------------------------------------Just the 1 task? Other tasks are fine? Is it using any CPU time at all? Has the other wingman returned his task? If other tasks are running fine, there may something wrong with this task, in which case, I suppose you should abort it.  - AMD Ryzen 5 1600AF 6C/12T 3.2 GHz - 85W - AMD Ryzen 5 2500U 4C/8T 2.0 GHz - 28W - AMD Ryzen 7 7730U 8C/16T 3.0 GHz |

It's just this one task, other tasks get completed in the normal way.
Yes it does keep one processor on 100% so it takes resources. Yes the other wingman has returned the result. I guess I should abort it.... |

It does sound like it's stuck.
----------------------------------------One thing I didn't ask: Did you reboot the machine? - AMD Ryzen 5 1600AF 6C/12T 3.2 GHz - 85W - AMD Ryzen 5 2500U 4C/8T 2.0 GHz - 28W - AMD Ryzen 7 7730U 8C/16T 3.0 GHz |

Any advice appreciated, thanks Willem Running Linux Mint 19 Tara [4.15.0-115-generic|libc 2.27 (Ubuntu GLIBC 2.27-3ubuntu1.2)] If your ARP1 task has been showing 99% for the past two days, then the last stage (compression of the result) is in progress, but has stopped/failed/died due to certain circumstances. You could try to revive the task. How? Try this. Rollback the task to its last checkpoint (87.5%). If you're low on memory, try reducing the number of running tasks. Example: pause all tasks, except ARP1. Next: stop BOINC, then restart BOINC. Look if the ARP1 task rolled back to 87.5% and has restarted. Then wait till it finishes. |

sorry I already aborted it...
Doing that I got this in my event log: Tue 15 Sep 2020 09:52:36 PM CEST | World Community Grid | Computation for task ARP1_0004129_024_1 finished Tue 15 Sep 2020 09:52:36 PM CEST | World Community Grid | Output file ARP1_0004129_024_1_r1922689250_0 for task ARP1_0004129_024_1 absent Tue 15 Sep 2020 09:52:36 PM CEST | World Community Grid | Output file ARP1_0004129_024_1_r1922689250_1 for task ARP1_0004129_024_1 absent Tue 15 Sep 2020 09:52:36 PM CEST | World Community Grid | Output file ARP1_0004129_024_1_r1922689250_2 for task ARP1_0004129_024_1 absent Tue 15 Sep 2020 09:52:36 PM CEST | World Community Grid | Output file ARP1_0004129_024_1_r1922689250_3 for task ARP1_0004129_024_1 absent Tue 15 Sep 2020 09:52:36 PM CEST | World Community Grid | Output file ARP1_0004129_024_1_r1922689250_4 for task ARP1_0004129_024_1 absent Tue 15 Sep 2020 09:52:36 PM CEST | World Community Grid | Output file ARP1_0004129_024_1_r1922689250_5 for task ARP1_0004129_024_1 absent No I did not reboot the machine.

Maybe it could have helped. The task would have restarted from the last checkpoint.
----------------------------------------Although a reboot wasn't necessary as going to the BOINC prefs, disable LAIM, pause the task, unpause the task and enable LAIM again would have had the same effect ;) I'll also install LM XFCE once the SCC project starts again! - AMD Ryzen 5 1600AF 6C/12T 3.2 GHz - 85W - AMD Ryzen 5 2500U 4C/8T 2.0 GHz - 28W - AMD Ryzen 7 7730U 8C/16T 3.0 GHz |

No I did not reboot the machine. It's not Windows ;-) Of course, enzlinux.  You said it yourself: Running Linux Mint 19 Tara [4.15.0-115-generic|libc 2.27 (Ubuntu GLIBC 2.27-3ubuntu1.2)]  Would you use “sudo service boinc-client restart” or "systemctl restart boinc-client" to restart BOINC?  |

I had a task do this same thing earlier today. What I did to fix it was:
----------------------------------------Go to the BOINC client Options > Computing Preferences > Disk and Memory > check the box for Leave non-GPU Tasks in Memory when suspended. Click save. Next select all tasks in the BOINC client and suspend them. In the Projects tab select WCG and suspend it. Wait for a minute or so while everything stops processing and the system load drops then resume the WCG project. After that go back to the Tasks tab and resume the stuck job. Once it wakes up again it will start the process of finalizing the task and uploading it. When it starts uploading you can resume all of your other tasks. I hope that helps in the future.

sudo service boinc-client restart adri, Do you run BOINC as a service? I thought there was a problem doing that such as one can't use BOINC Manager or BoincTasks. I use: sudo /etc/init.d/boinc-client restart  ...KRI please cancel all shadow-banning |
