High Memory usage

Anybody think this is too high for memory usage?

KBCFR2SW05#sh memory free

                Head              Total(b)       Used(b)         Free(b)        Lowest(b)  Largest(b)

Processor    2CD323C    79201732    67788360    11413372    10384280     9820936

          I/O    7800000     8380416     3594216     4786200     4602300     4784744

This is a 3560G-PS-48 switch IOS 12.2(50)SE1 with about 24 IP pnones connected as well as various types of servers.

the cpu runs about 10 to 20 %. But when I check the history of memory usage I see that it has been 80% usage for very long time.

High Memory usage

Hello John,

I would check the output of show proc mem sorted for a while and look specifically at the holding column and see if a process keeps large and increasing amounts of memory over time. This will help you rule out any memory leak issue.

Thanks for the response.

I see that energywise is the biggest holder of memory

This is just 1 of three switches for which I configed energywise.

I forgot that I even configed it because it was so long ago.

perhaps I should just remove the energywise config?

Here is another switch that has energywise configed
