Found resolution.

After carefully looking to zabbix_server.log found errors:

zabbix_server [3310]: Error waiting for process with PID 3359: [10] No child processes

I was not lucky as at the same time (when updated OS and restarted zabbix-server) hit HistoryCache limits ....

Changed History cache parameters to :

HistoryCacheSize=160M
HistoryIndexCacheSize=40M

And now zabbix_server not crashing .

Thank you for the update.

Nothing to fix. Just some misconfiguration.
