Exceptions filling logs and memory leaking till operational freeze

[unlstorm]

Using client/server v2.0.3 libtorrent: 1.1.13.0

Believe this existed since my fresh installation a few days ago but I never noticed it the first few days until logs filled and RAM skyrocketed. I'm running delugevpn in a docker container on my Synology NAS.

deluged.log is filled with the below error (3 to 5 events every 2 seconds: 00:08:16 [CRITICAL][twisted :154 ] Unhandled error in Deferred:

Traceback info from supervisord.log appears (repeated constantly) as shown below: 2019-11-20 00:10:07,608 DEBG 'watchdog-script' stderr output: Unhandled error in Deferred:

This is result of using Python 3.8 and a fix has been merged to develop: [351664ec071daa04]

I still get this error in deluge 2.04.dev24, see: ​https://pastebin.com/x5wswT7H

Replying to jools772:

I still get this error in deluge 2.04.dev24

This is actually a slightly different issue to the OP as it is propagating from Twisted logging, this has been fixed in ​Twisted >= 19.7

I shall handle the error gracefully and can skip logging under these circumstances.

And hope of resolving this? This problem is rather annoying. I started a dupe before seeing this: #3423
