Logs empty, amanda backup not runnnig

Hi!
i’ve been running this setup for a while now, but a week ago the amanda backup mail stopped coming so i looked into events.log / openhab.log and there weren’t any entries for several hours.
as far as i know habpanel and all my rules kept working.
i made a reboot and afterwards i got my daily amanda backup (successful) and entried began to reappear in the log files.
now i have the same problem again. no entries in log files since 2021-07-24 16:01
this is the last entry in openhab.log

2021-07-24 16:01:19.715 [WARN ] [me.core.internal.events.EventHandler] - Dispatching event to subscriber 'org.eclipse.smarthome.io.monitor.internal.EventLogger@1c9dc86' takes more than 5000ms.

zram is active, log files should be written there. shouldn’t be a memory problem, should it?

has anyone an idea what my problem could be (and how it could be solved)?
thanks in advance,
Peter
