Beetwen 01:10 am and 01:12 am (2 minutes) zabbix was running but all items was in queues and data was not collected.
Lot of zabbix agent (all servers) do not respond and no data alert.
Cpu and memory was ok. Mysql working well.
We have zabbix since beginning and this is first time I have this error message : could you tell me what's happen ?

Version of zabbix is 3.4.3 (I can't select this version on select)
