Network errors - and crashing after android app access

[pyoorkate]

Hi folks,

I'm needing a little help with my subsonic set up. It was working fine, but recently it started to misbehave:

- Inside the network:

- It works some of the time from a web browser. As you click through menus or through the albums it gets slower and slower before eventually reaching a point where the page doesn't load (doesn't provide an error message, but just spins constantly with the page loading indicator running).
- Using an android app (Dsub running on android 7.1.1) usually it won't manage to load the list of available audio - usually reporting "A network error occured" followed by "no data"

Restarting the subsonic service will reset it back to the above states.

Accessing via the internet:

- Using a web-browser: As above - but usually the server actually becomes completely unresponsive after the first click or two.
- Using an app: Usually goes straight to "A network error occurred". If not, it will do that every time after you select an album or track. It fails to load the artist bio.

Troubleshooting steps so far:

Removed and rebuilt database: No effect
Disabled the video portions of the library: Seems to allow a few more clicks before it falls over.
Checked that the router and server are configured correctly (Static IP with port forwarding for the router. No other obvious issues on the server. Also use Plex for some stuff, and that's working fine).

And the subsonic.log looks like this (edited for space - and I've pulled this from a terminal prompt, if it's useful I can pull the file off the server, but it runs headless and MacOS at it aren't friends):

Any help would be much appreciated as I'm not really sure where further to go.

[toolman]

You could try to increase the memory size allocated to Subsonic to 256 MB.
viewtopic.php?f=6&t=3939 explains how to do this for various operating systems.

Okay - gave that a go. Memory limit is now 1024k. Unfortunately this doesn't seem to have solved it.

Error is often the outdated FFMPEG.exe version. More on this bug here:

Thanks! Reading through that I understand it's suggesting switching back to an earlier release of ffmpeg. The versions I've now tried are:

None of which seems to have an impact on the issue.

Help?

...anyone have any suggestions?

I've now tried reinstalling Subsonic without success (not a complete clean install, but I'm beginning to think that's the way I'm going to have to go). I'm just not super enthused about spending the time removing it and reinstalling it if it's unlikely to fix it, or if this is going to happen again fairly soon...

[toolman]

You might have a look at https://github.com/dough10/PolySonic/issues/64 which discusses the problem and a possible workaround. ( I.e. Lowering the bitrate.)

Thanks for the suggestion - it *seems* to have started working again (at least with one app - however using DSub which has been my go-to (for its caching ability) seems to cause it to crash immediately). I'm not getting pauses in playback, or before playback, however. Just the application dying. Interestingly, now that the web-side of it seems happier it's leaving those apps that have failed in the list of "now playing" as playing whatever track they were playing when it fell over.

So I'm not sure now if this is an app issue, or a server issue. It seemed to be all apps when I first posted, but like I say, currently at least one other android app is working.
