EMBY server crashing whenever I perform local database reset in emby for kodi addon (log attached)

October 26, 2017

Whenever I try to perform a local database reset + initial sync in my kodi machines (Nvidia SHIELD, using Emby for Kodi addon), my CPU usage status on synology jumps to 99% and after a couple of minutes the EMBY server package crashes/stops running on my synology.

If I order it to start again, it does, but crashes again after 2 minutes or less as long as its running the initial sync KODI side.

"Gathering movies" runs ok emby for kodi side, but as soon as that finishes and it actually starts to pull movies 1 by 1, my CPU usage on the Synology jumps to 99% and the emby server stops/crashes.

I am on latest versions everywhere (server and client). Don't have ANY idea of what is going on

I sucessfully made a local database reset/initial sync on one KODI machine. NVIDIA shield one is making all of this happen...

Here is the logs from synology EMBY:

There is no obvious source of crash. I wonder if it is just getting hammered with requests from the syncing process and that is causing some kind of out of memory error.

While we are here, have you checked out EmbyCon? It's a new add-on that allows you view your Emby library in Kodi and does not require any syncing process. Just browse and play. You can learn more here:

Thing is, I succefully synced database from one kodi machine without crashing. Its only happening on the 2nd sync attempt on a different machine :S

I really need this to work as its my main machine (living room). Maybe i create a thread in the synology section? This never happened before and I always had a big collection....so the hammering is out of question or is there any setting I can modify the number of requests the emby for kodi addon does? Currently, regarding artwork its on 25 (as always).

Regarding that addon i am aware but unfortunately it does not allow full skin integration with my kodi machine

Sorry I just though asking you to merge indeed.

Maybe @@solabc16 can lend an extra hand?

I will try and run diagnostics to post the results. This is really something which never happened before. So the excess of information request was always present as I always had a big collection...Something is making emby server use 80% of my CPU on "Initial syncs" from the addon.

My synology is pretty decent: 1813+....

I keep getting these thrown into the log:

How can I downgrade my current EMBY for SYNOLOGY version? Just to rule that out...

EDIT:

@@Luke Does "library.db" hold the IP address (per entry AKA movie/tv show) of the hosted server? I mean I cannot seem to open that .db file with notepad ++ and last week I changed my synology ip from 192.168.1.200 to 192.168.2.200 and changed everything accordingly. The thing is, maybe library items prior to that change still hold the old ip address hence slowing down the sync process requested by the emby for kodi addon, which is making the server peg my CPU usage to 99% and then crash?

Or is this issue (i.e. the IP replacement) automatically done on each emby server library update?

EDIT2: i get these results on the emby for kodi log:

Wierd wierd stuff going on...

The server is crashing, not the add-on.

Try removing the kodi sync plugin.

October 27, 2017

The timeout is related to getting artwork from your server. That's internal to Kodi but the addon forces it. You can disable that behavior in the addon settings > sync option > disable force artwork cache Or decrease the number of threads for artwork (which is right below the option)

@@Luke The thing is, EMBY server only crashes/stops when the emby for kodi addon performs local database reset + initial sync. The addon gathers the movies fine but when it starts showing them 1 by one (I guess when the requests start?) 2 minutes later the EMBY app on my synology hits 99% CPU usage, crashes and stops (attention: my synology is NOT crashing) just the EMBY server package that is stopping (and, when it does, CPU usage returns to normal).

All other EMBY server usage (from database scan, to peoples refresh, etc etc) performs OK. Not even 20% of the CPU is used. So...this is addon related in my opinion, or some specific issue to the latest server packaged for SYNOLOGIES. I mean...this never happened. And I provided all the logs I could and it doesn't help...it's frustrating.

@@Angelblue05 I will try and reproduce those settings altough I've already tampered a little yesterday to no avail. In the meantime I have copy+pasted the .db on one of the kodi machine to all others and the initial sync does not make the emby server crash (because everything is already in place of course). But I will try removing the "force artwork cache" (specially, because all other options, when reduced, produced the same result: crash).

Ive tried 1 download thread, 2 download threads...

Maximum items per thread to 20, 15...

Limit artwork cache threads to 5...10...

Nothing worked. I just need to uncheck force artwork caching and test. Anyway I want artwork cached so lets see if it runs well if I uncheck on the initial sync and if when I manually ask to cache the artwork via the built-in option it crashes the server or not...

This is so strange. I use this system for 1 year now. AND IT NEVER HAPPENED...

@@solabc16 can this be related to the server Version 3.2.34.0 having a bug?

October 29, 2017

Why not confirm force cache artwork first? I don't see how the fast sync would be causing this issue. It only runs when the websocket receive events. When the initial sync is running in Kodi, technically nothing is triggering the websocket and therefore the fast sync remains idle, so it makes no sense for that to be the issue.

Hello All

For those of you having problems, can you run the send logs utility please, this will give me more information.

Details here: https://github.com/MediaBrowser/Wiki/wiki/Synology-:-How-to-Send-us-Support-Logs

Just post the reference you get at the end, once the utility has run.

@@nvader2000, are you running the Kodi plugin as well? What is happening at the time the server stops?

This "PID file [/var/packages/EmbyServer/target/var/embysvr.pid] does not exist" in itself is not an error, it just means the server isn't running - we'll need to look elsewhere for the root cause.

I was reviewing logs due to Emby not running. I could start Emby but as soon and I try to browse my media it would stop. I have since backed up my Emby srever, uninstalled and install version 3.2.35.0. But now I cannot restore. I did use the Emby Backup Plugin which was successful, but now when I go to restore nothing happens. Nothing is restored. Thought that a restart was needed and that did not work either.

I am a bit frustrated that a simply procedure is not working. Is there a way to manually restore? Can I simply copy the contents of the backup folder to where Emby is installed? If so, where do I copy to?

October 29, 2017

Ok so there was an update to the Emby Backup plugin that may have resolved my issue. Release notes indicate a compatibility fix. Possibly with 3.2.35.0. Thus far every looks good after the restore.

October 29, 2017

That will have no effect on this.

I already ran that utility, scroll up.

Since the latest version I have not tested it again.

I will (backup, of course, or I will lose it forever lol) reset my database and rebuild via EMBY for KODI plugin WITH artwork caching ON, and see if it crashes the synology package or not.
