Hi All,

I am facing high memory utilization in Cisco 2960 switch having IOS version 12.2(55)SE3.

The error we are getting is:

A "LiveHealthAlarm" event has occurred, from SwCiscoIOS device, named Switch2960.  eHealth Alarm Start Time - Fri 09 Nov,2012 - 03:02:48 eHealth.

Switch2960-RH-MemoryPool-Processor-Processor-1.Memory utilization high-Threshold set at 70%SPECTRUM ALARM ID|22233284

I have attached the logs also.

Shahab

There are a series of CPU bugs affecting the early versions of 12.2(55)SE.  This has been rectified with the 12.2(55)SE5 or 12.2(55)SE6.

Hi Shahab,

The memory on your 2960 is only 24MB. Currently you have ~7MB Free.

Cisco2960#       show proc mem sorted

Processor Pool Total:   23407304 Used:   16435636 Free:    6971668

Init process is holding most of your memory 13696144. No other process is holding more than 1MB. So I am not seeing any serious memory leak here. Dead memory is hodling around 600K memory which is very less

Init process is holding memory as per your configuration. So this should be expected memory utilization as per your configuration.

Thank you

Raju
