LE 12 Playback stuttering

On a fresh install with fast wired connection. Cpu- and memory load low as shown in kodi.

I generated a log and would be happy if someone with the appropriate knowledge could give me a hint what to do: https://paste.libreelec.tv/useful-starling.log

Thanks!

Thank you for the fast reply. I tried playing the file local (from usb), what in fact didn't stutter as opposed to the network (a logfile with first playing locally then over network ist here: https://paste.libreelec.tv/daring-killdeer.log)

BUT: I am firmly convinced, that the reason isnt't the network but libreelec. The fileserver is running an SSD-raid 5-array, connected to the rest of the network using dual 10G SFP and is reliably able to handle loads in magnitudes very different from streaming some mkv (which by the way is only 1080p). In the house there are six other Kodi installations (on Windows and Android) functioning flawlessly on the same network. I tried connecting other devices to the switch port libreelec was on: Kodi on Windows and Android was no problem, and file transfer using Windows SMB is stable at near-perfect 1G/s (which is the limit of the laptop.

So alltogether I agree that it is a networking problem, but it seems to be caused by libreelec. Any ideas?

Thank you all for your input! After trying nearly everything and going half crazy about the problem beeing randomly present or not, I finally found the culprit: a loosened rj45 connector... (probably because someone slammed a wardrobe against it). Crimped a new one and everything is back to normal.
