Ubuntu unhandled exception log created daily at 5am

Hi All,

 

Does anyone know what is happening and/or why?

I am getting an unhanded exception log on a daily basis at 5am.

I guess a scheduled task is running into problem, but I cant tell what is it.

From the log the main think that sticks out is a sqllite locking issue.

 

The only thing weird I have noticed on my server is that a bunch of TV shows are not available.

Its possibly off topic so I have posted about this issue separately as I dont want to pollute this thread.

 

here is the log:

htpc@ubuntutv:/var/lib/emby-server/logs$ cat unhandled_39663c63-c883-4c5b-977a-aec5c4622834.txt
One or more errors occurred.

Technically there is not task set to run at 5am, you can click on each task and see what they are set too.  Majority are set to run at interval, 12 or 24hrs.  There are a couple set at specific time (unless non-Windows scheduled task are setup differently which I doubt).

database is locked

Do you by chance have more than one instance of Emby server running?

Which one of your scheduled tasks runs at 5am?

 

Good question!

I didnt realise that you can see the scheduling when clicking the items :)

So the only one I can see on a fixed schedule @ 5am is "Refresh People"

I ran the task manually and finishes ok...

 

But I found the issue and its of my own making - I have a cron process that is checking if letsencrypt SSL certs need to be updated.

It runs at 5am... bingo. Need to fix that script I think.

 

Thanks for the input folks

Not purposefully, but I my script is supposed to restart emby if (and only if) SLL cert was updated, but I think there is a typo in there somewhere and the restart is resulting in dup server.

Ty for inputs.
