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.
