Based on the kernel version you're most probably running my latest OMV build? If that's the case it might be related to zram (since I realized too late that with a btrfs rootfs no 'vm.swappiness=0' is set but the default applies (60 IIRC, please check with sysctl and report back whether disabling zram changes something or not).

Hello Tom,
sorry for late response, but the forum-sw didn't send me an email per default on reply to my thread…
yes, the XU4 was on OMV, but the same thing happens with pure armbian. (see below)

not sure what you are asking about: "disabling zram?"

 

sysctl -a |grep swap

vm.swappiness = 0
