Thank you sir.
1) In my case, There will be single thread dedicated for snmp-agent. Which
going to handle request. Agent will not create any threads.
2) When I complied my_snmpd & copied it to other machines with all necessary
libraries then,
$./my_snmpd
symbol look_up error: /usr/lib/libnetsnmpagent.so.15: Undefine symbol
boot_Dynaloader
This problem does not occurred if I run it on that machine where I have
installed net-snmp.
