Description Tom Seewald 2021-11-25 16:31:16 UTC

Description of problem:
After running deluge-gtk for a period of time (~30 minutes to an hour) it will begin filling the system journal with the following twisted error that repeats once every second.
Stopping deluge causes the errors to cease.

Version-Release number of selected component (if applicable):
deluge-common-2.0.3-18.fc35.noarch
deluge-daemon-2.0.3-18.fc35.noarch
deluge-gtk-2.0.3-18.fc35.noarch
python3-twisted-21.7.0-2.fc35.noarch

How reproducible:
Always.

Steps to Reproduce:
1. Start deluge-gtk
2. Wait for ~30 minutes

Actual results:
The above error and backtrace is logged to the journal once per second.

Expected results:
No errors filling the journal.

Additional info:
I have not noticed any functional problems with deluge, however having the system journal spammed is far from ideal when investigating other problems.

Comment 1 Tom Seewald 2021-12-04 16:47:16 UTC

Upstream has a fix for this [1], but it is not yet in an official release of deluge. I can confirm that with this change the errors have ceased.
