## Symptoms

- * SNMP functionality on Gaia machine breaks intermittently (stops answering SNMP Queries, stops sending SNMP Traps).

* */var/log/messages* file shows that SNMPD process is being repeatedly restarted:

  ```
  
  kernel: snmpd[PID] trap divide error rip:... rsp:... error:0
  pm[pm_PID]: Reaped: snmpd[PID]
  pm[pm_PID]: Scheduled snmpd for +1 secs 
  pm[pm_PID]: Restarted /usr/sbin/snmpd[New_PID], count=X
  ```

* After enabling the generation of core dump files (per [sk92764](http://supportcontent.checkpoint.com/solutions?id=sk92764)), core dump files are generated for SNMPD process in */var/log/dump/usermode/*.

* SNMPD core dump files contain the following stack:

  ```
  
  Core was generated by `/usr/sbin/snmpd -f'.
  Program terminated with signal 8, Arithmetic exception.
