Hey people!
My OMV installation has been buzzing along nicely for nearly two years now, but in the recent days it has completely frozen on me 4 times. The system is completely unresponsive (webgui en local) and requires a hard reboot.
After a reboot I find lots of errors in the syslog, see below for a small selection (it's usually several pages).

How would I start to troubleshoot this? My fear is a piece of hardware is starting to fail but I see no indication as to what it could be. Searching online gives me mixed results. The NAS is used as file storage en Plex station.
Thanks for any advice!
