Emby crash System.OutOfMemoryException

[dv1r 27]

Hi,

I recently update DSM to 7.2 and in addition, I updated emby server to the 7.2 build Version 4.7.13.0

The update took place on the 17th. Since then, emby crashed twice. First time I let it slide. Second time I looked into it.

This is the last lines in the log before the crash:

While looking through the log file, I see this recurring exception: (not really sure how to approach this one)

When the server crashed, the system was at 47% (out of 32GB) and the storage has a few TBs free.

Before the crash, there we a remote user watching trans coded media.

Looking at the system memory around that time you can see the memory increase over the viewing session and then crashing:

The red line is the start of the viewing session and you can see where the service crashed at 47% ( that's about 1.9GB increase in memory usage).

After the crash,  the system is at 38%( About 2.9GB freed up).

 

Any idea what I can do about this?

 

Thanks for reading

Its been quite a while since i last posted a question here.

Is there a new format for posting technical questions that I missed?
