snmpd error on starting...

Hello,

I have 2 servers with the same configuration and with UCD-SNMP version 4.2.5
When I throw the process snmpd on the server A, no problem, the requests
pass correctly.
When I throw the process snmpd on server B, the process rushes and stop at
the end of 10 seconds and generating a core file.
No information found in the file of log of snmpd...
Where is the mistake ?

Thanks for your help,
Laurent
