Summary: snmpget - delay in sending GetRequest

Initial Comment:
Code for re-producing behaviour:

#!/usr/bin/perl

$ip='n.n.n.n';

while (1==1) {
  $n++;
  $t=time();
  $r=`snmpget -m SNMPv2-MIB -r 0 -t 1 -OvQ $ip 
sysDescr.0`;
  $td=time()-$t;
  chomp($r);
  print "Sequence:$n, Time Elapsed:$td, Response:$r\n";
}

#############

In a second terminal window, run tcpdump 'port snmp'

When snmpget "Hangs" for a few seconds, the last 
packet tcpdump displays is always a 
snmp "GetResponse" ie. the last response from the 
previous snmp "GetRequest".  This indicates that 
snmpget is getting hung-up somewhere before it sends 
out a request.
