Latest version of Emby - Random lockups - Connection Timeout to https://api4.thetvdb.com

[vaise 340]

This has happened twice in 2 days now - An Emby restart fixes it.  Unlike the first time, this time I was in a position to get some logs.

It seems this happens over and over - the below is repeated 25,000 lines in the logs, all in the same few seconds.  Emby is just a spinning disk when this happens.  I know you will be asking for the full log, so I will also upload that.  If there is a comms issue, or if there is an API issue, this should not stop Emby working should it ?

See the log of 25,000 lines all at 19:10.00 ish.

embyserver-63925096289.txt

[vaise 340]

Further info - This is running on a docker container on Unraid.

I have been stable for ages.  New version installed 3 days back.

[Luke 43109]

hi there, what makes you think Emby stops working?

[Luke 43109]

What I can see is that something external is hammering your server with requests for episode listings and this is causing huge numbers of requests to go out to tvdb.

[vaise 340]

I have not changed anything for a long while.  Except emby upgrade.  By all means I can shutdown jellyseer, which if the only external thing.  But it has its own request thing, it does not request emby do this.

[vaise 340]

The log I imagine shows my plugins.  Could it be conversant or something that is incomparable with the later release?

[Luke 43109]

If you can get it to happen again with debug logging enabled then that may tell us more.

[vaise 340]

As to what happens when it stops working, the first time, I got calls from a few friends, but as I was away, I just did a remote restart.

The second time I was watching it myself and just got the spinning disk, and then calls from others, and EVEN the Emby console was not responding - refresh in the browser and timeouts.  I again restarted the docker container and all good again.

I just checked the jellyseer logs and it is going to do a full Emby sync in 15 hours - I will be in bed then.  I don't think it's that as it runs every 24 hours and this issue was at 7:10PM.

To rule it out however, I just kicked off a manual full Emby sync.  Checked Emby logs and processes - no impact and little log activity.

With regards to external access - I have check log files for the same timeframe for jellystat, seerr, Nothing else does any sort of sync.  My API keys are thus - 

Any idea what order, or what below may be the culprit for removal from the plugins - 

 

[vaise 340]

FYI - I am happy to kill all api keys and reset those apps, plus I am happy to kill all manually added plugins for a fresh system, I was just looking at an order of which is more likely to be the culprit.

[vaise 340]

I have started re-assessing plugin needs anyway - first one autobox sets - failure - so that is being removed - 

[Luke 43109]

I think a debug log is the best next step.

[vaise 340]

How would I manage to get that happening, when I don't know when this may occur next ?

[vaise 340]

Same thing happened tonight, and 24 hours later - also around 7PM.  Checked logs.  Different stuff.  Lots of covert processing - I have deleted that plugin.  Will pay close attention tomorrow at the same time.
