I am reading here for a while, now i encounter an (for me) unsolvable problem..
My system randomly hangs and is unresponsive (all docker container / services are not reachable). SSH login works but if I for example run "top" it hangs/freezes as well.
I think (haven't verified if this is always the case) I can make the system responsive again, if I login to the webinterface (OMV GUI). Once logged in, the system will return back to idle state and remain with low load..
Until now I couldn't find a single source for this, checked the process logs, iotop etc.
Is it possible that the GUI will "lock" the system somehow? How can I get logs if the system hangs?
I currently run a OMV backup with fsarchiver, which is utilizing the CPU quite a bit, but runs smoothly with load of 2.2-2.4. I don't know if this one is the cause for the initial high load and the freeze of any other processes..
