With the latest version 1.9.0 of syncting running on my NAS (NUC with Atom N2830, single SSD) and openmediavault the system is instable, partly not reachable. Turning syncthing off it runs stable. With earlier versions I had no problems. I tried to follow this recommendation to set maxFolderConcurrency to 1 but still.
this is how the load graph looks when syncthing is on with a lot of holes where the whole system stalls
and here is the pic when syncthing is turned off at ~11:45; the system is stable
What else can I do to stabelize the system. Should I go back to an earlier version of syncthing?
