hi,
I’ve been trying to solve the following problem for several days but haven’t found any solution yet. So I posted a similar thread on the official kodi forum. Unfortunately nobody has answered so far. So you are my last hope 
I have a windows server with a mediaportal tv server and a raspberry pi3 running the latest osmc version as client. As long as the server is running everything works fine. It’s configured to turn off if kodi doesn’t need it.
So usually when I go to bed I watch some tv and have kodi to turn streaming tv off after some time. Then the server turns off. The pi is running 24/7 which means that the pvr addon can’t connect to server from that moment on.
Then the MP pvr client writes some errors to the log which imo is ok because the server is off. But after some hours it produces a ‘process file table overflow’. From that moment on I can’t use kodi anymore. Windows won’t open (even the screensaver), I can’t access any menus and so on. For hours it produces the error 113, then once 110 and from that moment on 24.
Then a reboot is neccessary.
As far as I know error 24 means ‘too many open files’. But why is this happening and what can I do?
The following snippet is from my log file (with debug on) when the error occurs.

Those errors then repeat until I try to use Kodi. A simple moving in the menu or trying to access the movies creates the following:

I then have to restart Kodi because it won’t do anything anymore.
Does nobody have a clue? Am I the only one using this addon with a tv-server that’s not on 24/7 or does nobody else have this problem? I’m no crack in this but for me it sounds like the pvr plugin tries to connect to the server every 5 minutes. And for every attempt it opens one connection (without closing it?). After some maximum the error occurs.
Could one make those connections to close after the attempt? Or am I completly wrong?
Thanks a lot for any help.
