Layout keep restarting after 10-20 min of playback

I have 2.3.8 Doker version with a DSCS player. Until one month ago everything running ok, except the non-working Intrerupt Layout.
Now I see for this display it’s keek restarting from point 0, after 2-3 times sub-playlist plays. The full layout has to play for 30 hours, with 20 playlists with pictures and videos in Round Robin and Repeat configuration for the Sub Playlist.

Have any one this problem? @DanBW & @dan can you please assist?
