Hi,
Yesterday I've updated omv from 3 to 4.
I've noticed strange occurence. Two times today server suddenly starts beeping few seconds and everything stops working. I can't login to omv admin console, ssh is not working. Just hard reset is needed.
First time in some logs I found a lot of characters this type: ^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^.
Second time was clear. Anyone had similar behavior?
