Crashes

[pmolan 0]

I've used Emby server on windows for a while and has been pretty stable.  Recently I set up a VM server and thought to use Ubuntu Server as the OS for emby server.  I have it setup but it keeps becoming unresponsive every 10-15 minutes.  The error messages that I get in the logs every time it becomes unresponsive is :

Any ideas?

Please attach the full server log from when the system becomes unresponsive.

Thanks for looking

as a test, is it possible for you to allocate an additional cpu to the VM? I wonder if there is a threading bug in the mono runtime when run in a single core environement.

I can do that.  I will post back with any changes.  Thanks.

Good call...  I increased the CPU from 1 to 4 (because I plan on running a few other things on this at the same time anyway) and it has been up for 20 hours now.  Thanks!

[Luke 42077]

Great, thanks. I'm adjusting that anyway so that it will be fine on single core.

Great, thanks. I'm adjusting that anyway so that it will be fine on single core.

Does this mean Emby will be also running smoother on a Rpi? I still have frequently crashes (out of memory) of the Emby server service on my pi even with an additional swap file on USB stick and memory tweaking. Especially library scans eating memory...
