SNMP
SNMP memory usage continuously increasing
The show proc mem | inc snmp command shows continuously increasing SNMP memory usage.
Possible Cause
SNMP memory usage increases when SNMP requests are processed from different monitoring stations.
Typically, this situation stabilizes over time. If the memory increases continuously without stabilizing,
then some of the SNMP requests are causing a memory leak.
Solution
Review the output from the show system internal snmp mem-stats detail command.
Take example snapshots with the following commands while processing SNMP requests:
• show clock
• show system internal mem-stats detail
• show tech snmp
