Thanks Bill,

In which version this bus was fixed? 
Currently I am using net-snmp-5.4.2.1-8.2.1

Prakash,

There was a bug in earlier versions where if you tried to start snmpd
while it was already running, it would overwrite the old agentx socket
before failing to open the udp transport and exiting.  This would mean
that if the subagent ever got disconnected, it could never reconnect.

It's kind of hard to find out if this happened, since the daemon that
caused things to break didn't necessarily log anything.  I think you
can look at the timestamp of /var/agentx/master and compare it against
the start time of the current snmpd.
