## Symptoms

- * SNMP in Gaia is enabled but the Linux process is not starting, for example:  
  `
  hostname > show snmp agent`  
  `
  SNMP Agent Enabled`

* There is no output received from the 'netstat' command:  

  `netstat -anp | grep 161`

* No Core Dump files are created

* Similar logs are found in */var/log/messages* file:  

  `
  [DATE TIME] hostname pm[10347]: Restarted /usr/sbin/snmpd[9489], count=5166`  
  `
  [DATE TIME] hostname snmpd: cprd/snmp_igmp.c-init_snmp_igmp (start)`  
  `
  [DATE TIME] hostname snmpd: init_vrrp called`  
  `
  [DATE TIME] hostname snmpd: init_coldstartTrap: snmp_alarm_register`  
  `
  [DATE TIME] hostname xpand[10365]: admin localhost t -volatile:configurationChange `  
  `
  [DATE TIME] hostname xpand[10365]: admin localhost t +autonomous:snmp:v3:engineBoots 33005 `  
  `
  [DATE TIME] hostname xpand[10365]: Configuration changed from localhost by user admin by the service /usr/sbin/snmpd`  
  `
  [DATE TIME] hostname snmpd: Destroying the lists of sensors`  
  `
  [DATE TIME] hostname pm[10347]: Reaped: snmpd[9489]`  
  `
  [DATE TIME] hostname pm[10347]: Scheduled snmpd for +900 secs `

* "Server Exiting with code 1" in the output of snmpd Strace, for example:
