## Symptoms

- * System stops responding to snmp polls after about 248 days. Restarting the snmpd resolves the issue for another 248-days or so.  

* Affected systems:
  * SecurePlatform versions prior to R70
  * IPSO versions 4.x and 5.x, which are running Net-SNMP v4.1.1

## Cause

NET-SNMP versions earlier than 5.1 have 32-bit counters for uptime.   

NET-SNMP keeps time (timeticks) in 1/100th of a second units. So, a 32-bit counter can have a maximum number of...   

2^31^ - 1 = 2147483 647   

When we convert this into days we get...   

(2^31^ - 1) / (100 x 60 x 60 x 24) = 248.551348 days   

Using the following integers:  

100: 1/100th of a seconds value for timeticks   
60: seconds per minute   
60: minutes per hour   
24: hours per day   

Once the system time (timeticks) for snmp reaches the above value for 32-bit counter it counters a 'not-in-time' window.
