Hi,
I am having an issue with SNMP and FreeBSD. Everything is working fine on a daily basis but every two weeks I get an alert SNMP Failed on all my FreeBSD vms (seems to be related only to FreeBSD, others are fine)
2 hours laters SNMP recovers itself. Alert logs below.
Where should I start looking for the cause?
