On a few hosts I'm seeing the following error in /var/log/snmpd.log, in the same times graphs for mysql application in LibreNMS are not working. Graphs for zfs app. are working

Code: 
send response: Failure in sendto
    -- NET-SNMP-EXTEND-MIB::nsExtendStatus."zfs"
    -- NET-SNMP-EXTEND-MIB::nsExtendStatus."mysql"
    -- NET-SNMP-EXTEND-MIB::nsExtendOutput1Line."zfs"
    -- NET-SNMP-EXTEND-MIB::nsExtendOutput1Line."mysql"
    -- NET-SNMP-EXTEND-MIB::nsExtendOutputFull."zfs"
    -- NET-SNMP-EXTEND-MIB::nsExtendOutputFull."mysql"
    -- NET-SNMP-EXTEND-MIB::nsExtendOutNumLines."zfs"
    -- NET-SNMP-EXTEND-MIB::nsExtendOutNumLines."mysql"
    -- NET-SNMP-EXTEND-MIB::nsExtendResult."zfs"
    -- NET-SNMP-EXTEND-MIB::nsExtendResult."mysql"

Code: 
$ freebsd-version -ku
13.2-RELEASE-p2
13.2-RELEASE-p2
$ pkg info |grep snmp
net-snmp-5.9.1_4,1             Extendable SNMP implementation
$ cat /etc/rc.conf.d/snmpd
snmpd_enable="YES"
snmpd_conffile="/usr/local/etc/snmp/extras.conf"
snmpd_nice="-5"
snmpd_flags="10.7.233.234"

Has anyone seen this before or has an idea what to check?
 
It could be anything network related (see sendto(2) man page, ERRORS section), try increasing snmpd verbosity to see if it would return the errno (instead of useless "Failure in sendto").
