Hello!

24/04 after update from version 6.4.7 to 6.4.13 (approx 15:00 on graph) observed problems with poller utilization. I'm tried to incrase pollers count from 50 to 300, but problem still exists.

ATM I'm have only 2 troubleshooting info: graph with utilization and logs from zabbix_proxy.log:

In log I see errors like this:

1159555:20240427:220106.260 SNMP agent item "fan.availability[3.2]" on host "hostname" failed: another network error, wait for 15 seconds
1159684:20240427:220106.767 resuming SNMP agent checks on host "hostname": connection restored
