Hi guys
I'm experiencing the following problem. I have a Zabbix 7.0.10 instance configured with several proxies, one for each customer (7.0.8 and 7.0.9 version for proxies, 7.0.9 for the proxy where there is the issue). Recently I started to monitor new hosts with SNMPv3 and after configuration everything works. Randomly I see that the local proxy stops collecting data from SNMPv3 hosts but everything else is collected.
snmpwalk for those hosts is perfectly working with, of course, the same settings.
If I restart the proxy everything works again, so it is neither a configuration problem nor an host problem, just localized on the proxy.
I tried to increase the SNMP collectors, though it shouldn't be correlated but the problems randmly appear.
Any ideas?
P.S. Here is a piece of log when the error happens. It SEEMS a network error BUT the proxy isn't able to restart monitoring on an SNMPv3 host until I restart the proxy itself. No problem with SNMPv2
