We are monitoring multiple IMMs using IMM Template via SNMPv3.

We have noticed a lot of data flapping, causing data being shredded.

SNMP interfaces setting, community etc. are set correctly, but still getting: Cannot connect to "host:port": Timeout.

Noticed the same problem in: ZBX-15391 but EngineID is set in IMM and is unique per IMM.

So we can not change EngineID in IMM.

snmpwalk works fine, what should we investigate to resolve the issue?
