Ah, was worth a shot.

Another possibility I seem to recall people having problems with is the use
of bulk responses.  In SNMPv2c, you can send a query for a tree walk and
get one single response (depending on size) with lots of OIDs in it, and
some devices might have problems with this.  If you switch the devmon
config to v1, you disable bulk responses, and it might be a bit more
reliable for some devices, although it'll generate a bit more outbound
traffic in some cases.
