Save Data stops working on dedicated Server still

[King_Maxi95]

After the Server was running for some Hours the progress wasn't saved anymore.
This means the Character doesn't save on client side, means that you log out and in the Main menu you see the last save date of your character is somewhere in the past and if you rejoin the server your items seem to be reseted to that date.
The server doesn't save too, but because the server is still running you only notice that when restarting the server and everything gets set back to the state it was on the last succesful save.

I looked up the logs of my server and this is what i found: ( my edits)

It seems that the game stopped saving after running for about 2:50h after failing once and than not trying again.
I checked the logs on other times when it happend most recent was today 31st january 13:12 GMT and the server kept running for another 2h till we noticed.

The in Hotfix 6 mentioned "On dedicated servers, the server will shut down automatically in case many consecutive attempts to save were unsuccessful." Did not happen and the save routine seem to be crashed complettly. The (savedata) Message didn't appear anymore in the logs after failed atemped.
