As the topic says, when I sync music, emby server crashes. Log File attached.

Basically, this is happening whenever I start the sync on the android app:

UnhandledException
Either the IAsyncResult object did not come from the corresponding async method on this type, or the End method was called multiple times with the same IAsyncResult.

Hi,how are you defining crash? there is no evidence of a crash here. I do see some sync download failures but not a server crash. If the issue persists I would consider upgrading to mono 4.4.2.

Look at the log file i attached above.

Seriously, do you even want to help? I am paying for you for this sync option and you don't even care to look at log files?

I missed that, apologies. The crash appears to be coming from the mono runtime and in a manner that we're unable to catch and recover from.  I would suggest updating the runtime and seeing if that makes a difference. i will look through xamarin's bug tracker to see if anything like this has been reported. thanks.

What mono version for ubuntu 16.04 is recommended?

[Luke 38864]

I would suggest 4.4.2, if available.
