I am implementing some of SNMP tables right now and I faced some misbehavior of SNMP agent.  
udpTable from rfc 1213 doesn’t work properly. According to my understanding it should work like that:  
udpLocalAddress.0.0.0.0.161 = 0.0.0.0  
udpLocalPort.0.0.0.0.161 = 161  
Istead of that the agent returns udpLocalPort.0.0.0.0.0 = 161 ( and no appearance of udpLocalAddress, lexicographically it stands before port, and why port index is zero?) and loops in it, so snmp walk is broken there. Definetely this is a bug and should be fixed.

Also I want to point out that agent hangs from time to time.
