ZRAM nightly sync, openhab service restart

Hi all,
I’v changed the time setting in the .timer just to be sure that is wasn’t the Amanda backup causing the freeze of both log files.
below are the last lines of syslog before it freezes, next morning i wake it up by HUP’ing it.

May 14 02:05:01 domoberry CRON[13933]: (root) CMD (command -v debian-sa1 > /dev/null && debian-sa1 1 1)
May 14 02:05:01 domoberry systemd[1]: Starting Perform nightly zram sync to persistent storage...
May 14 02:05:01 domoberry zram-sync[13943]: zram-config sync 2024-05-14-02:05:01-CEST
May 14 02:05:01 domoberry systemd[6276]: var-log.mount: Succeeded.
May 14 02:05:01 domoberry systemd[1]: var-log.mount: Succeeded.

To check the openhab logging i’ve made a test rule writing a logInfo line ever minute from 2:00
Below are the last line’s before if freezes

And yes indeed events.log continues to be writen as expected.
