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.
