Error: Only one usage of each socket address

I've seen this reported a few times and seems a simple server reboot does the trick, but I've been having this happen every day for the past week or two. From what I can tell, seems to coincide with the Server restart Emby task (scheduled daily @ 3:45am).

 

I've disabled that task to see for sure, then I can setup a Windows scheduled task to reboot the entire server if need be. Just seeing if anyone else has any thoughts or seen something similar? FYI, i'm running Server 2012 R2 Standard, Emby Version 3.0.5871.0.

every once in a while windows will take several minutes to release a bound port. when this happens, the above will occur if you try to rebind before the original assignment has been released. the best way to prevent it from happening is avoiding restarting the server when not needed.

Thanks Luke, it's been smooth sailing since disabling the restarts in scheduled tasks. I may just add a Windows task to kick the server once a week or so.
