[snmp] SNMP trap problem (thread count)

[Birgit Arkesteijn]

Hi Vijay,

First of all, try using the SnmpContextPool class.

Secondly, the thread will only be destroyed when you destroy the 
context. That isn't so straightforward with traps, because send() isn't 
synchronised, so you have to give the context a bit of time to actually 
send the PDU before you can destroy it. Try a few second sleep and then 
destroy the context.

Cheers, Birgit
