Universal Media Server | Forum

That whole topic does not seem to interest anybody.

Is Mac as a platform SUCH uninteresting?

So this problem comes from the ExFAT filesystem and "something" the server thinks it need to do on MacOS ...

This renders Universal Media Server useless on MacOS, as long as ExFAT is used.

Very very sad

I only blocked things to get rid of the high CPU usage!

I can unblock all, but that does sure not fix the CPU issue.

The Router offers network shares, maybe because of this it is interpreted as rendering device?!?

I noticed something interesting:

Together with UMS, 2 other processes are always at the "top":

fskitd

UVFSService



PID COMMAND %CPU TIME #TH #WQ #PORT MEM PURG CMPRS PGRP PPID STATE BOOSTS %CPU_ME %CPU_OTHRS

Thanks for having a look into this.


I don't see UMS doing anything in the logs. Was it showing high CPU usage when you made them?


Yes, it always runs at around 40-50% CPU.

I noticed that I cannot STOP it with a SIGSTOP signal, which is also annoying.



I don't have any more info as this ...

I read https://www.universalmediaserver.com/forum/viewtopic.php?f=9&t=556 on how to create debug logs.

Let me expand on this, as the description does not fit reality, as it seems:

I needed to use the Hamburger menu in the upper right corner.

From there, Tools / View Logs and select "Pack debug ...

I read saw similar threads, some quite old, some related to Java, but I saw no fix for this.

I disabled Thumbnail creation and also blocked any renderers that were deteced.

Still, UMS is constantly eating CPU time, it is the most active process on my Mac.

What is wrong here and what can I do to ...
