I think I may be running into an SNMP issue with the particular version of IOS I'm on. I get timeouts when querying the 3750 via SNMP. I can do an snmpwalk from the NAV server to the device, and it runs for a while, but it will sometimes time out.

Could you please try replacing snmpwalk with snmpbulkwalk, adding the option "-Cr50" and see if the timeout problem gets worse/better?

Using bulkwalk with a max-repetitions value of 50 will mimic ipdevpoll's requests more closely. I've seen some devices slow to a crawl when asked to produce a large bulk response (something which would normally reduce lag in snmp operations).
