need help - snmpd terminates as soon as it starts

I have several CentOS 4.5 machines at different hosts, where I have installed the snmpd service using "yum install net-snmp", but every time I try to start the snmpd service, it claims to start successfully but then terminates immediately: [shell]# service snmpd start Starting snmpd: [ OK ] [shell]# ps auwx | grep snmp root 29757 0.0 0.0 4376 624 pts/0 S+ 12:20 0:00 grep snmp [shell]# This only seems to occur on CentOS 4.5 machines, not CentOS 4.4 machines. The only thing it writes to /var/log/messages when it starts, is the lines: Jan 31 12:20:30 D2585 snmpd: snmpd startup succeeded Jan 31 12:20:30 D2585 snmpd[29749]: NET-SNMP version 5.1.2 which doesn't indicate an error. Someone suggested that I run it under strace, and this was the output, even though I don't understand any of it: '[login to view URL] I need to get this problem fixed so that when I start snmpd, it starts running and stays running. ## Deliverables I need a set of instructions such that I can start the snmpd service and have it continue running instead of dying immediately, which is what it currently does on all my CentOS 4.5 machines. For security reasons I can't give out remote root access to the machine but I'll try anything you suggest and I'll gather any information that you need. ## Platform Need to find out why this error is happening on CentOS 4.5. (The problem doesn't seem to happen on CentOS 4.4.)
