"No SNMPv2c response" during User Tracking collection?

[ww9rivers]

I have an LMS 3.2.1 server running user tracking collection starting at 11:30am. We also use InterMapper to monitor switches. Right around the time UT collection is running, InterMapper starts to alert about "No SNMPv2c response".

I am wondering if there are others in this forum who also run InterMapper. If so, has anyone experienced the same issue?

This could likely be an overrun on the IP SNMP process.  That is, the device is processing the SNMP requests of UT and timeout when InterMapper makes a request.  This kind of thing is particularly possible when the ARP table is queried with SNMP.  Try increasing your InterMapper timeout.
