16926 - Some sort of loops with this CPU WU

[VAcharonD1]

Some more logs, this time from Linux with 12 threads (apparently lowered to 3). I've also seen it happen on a regular 3 thread slot.

Linux noob here. Can some tell me how to dump a work unit in Linux? I'm on Ubuntu 18.04. My googling did not return anything helpful.

Do I delete the core or the work?

How do get around not having permission to rm?

[Yeroon]

You should be able to do it through the gui file manager. I dont recall any permissions issues but there is always sudo if needed.
WU locations on a default installation (at least how mine is) at /var/lib/fahclient/work/

Find your offending WU number, delete or remove to another location, restart said slot.

[Maddog]

Do not use sudo in a gui, it can mess up permissions.
In file manager, navigate to /var/lib/fahclient/work/ . Right click on the work folder and it should give You a dropdown menu.
Choose open as administrator. There should then be no problem deleting the WU folder.

[Lockheed_Tvr]

Sort of odd. Half the boxes allowed me to just delete the work folder from the gui, the others needed to be removed from terminal. There was no "open as administrator" option from the right click menu. "sudo rm -r 02" and then my password worked from the command line. Linux continues to confound me.

16926 (78,49,1) dumped on Linux Mint 20, 8-thread CPU.

[kjk]

Yeah, seems I'm also been been stuck with 16926 (90, 634, 6) for a while. Just noticed today the cpu was idling. My CPU slot is set to 8. I'm on 7.6.21 and Fedora 32 (linux2 5.8.0-1-amd64).
Thus dumping it.
