since this morning I observe a very strange issue. No major changes and/or upgrade before.
my Openhab Installation (Details see below) operates as normal, but out of a sudden it stops working. CPU actually freezes and according to my monitored metrics it remains on the level it was (have seen it with almost 0% util, but also with around 20%).
after around 6-8 Minutes everything is working again normal AND every event which hasn’t been processed during this period of time will be processed after it.
it seems that my eventbus stops working, the event.log doesn’t show any record in this time. The openhab.log shows me that cron-triggered rules are working, but no status changes are written to my items.
i do not have any high cpu loads, i/o loads and memory and diskspace are fine too.
Until now i cannot really narrow it down to any specific binding, or thing or whatever… when setting logs to debug i also cannot really find something very suspicious.

Openhab: i have around 400 rules, 2000 items, around 100 things.
around 20 dashboards in Habpanel and constantly 4 devices displaying it.
but above things were running perfectly fine for months…
Has anyone any idea what it could be or at least where I can start troubleshooting?
