3650 showing high memory

[OmarFR209]

hi, just wanted to check if anyone has had issues with cisco 3650 running 16.3.3 and high memory usage, the switches were installed in may 2017, we haven't had problems, but the high memory usage keeps ringing a bell for me, i ran the command:

#show platform software status control-processor

this is what i see:

Memory (kb): healthy
Total: 3958032
Used: 3286836 (83%), status: healthy
Free: 671196 (17%)
Committed: 3921944 (99%), over 95%

any recommendations?

Thanks in advance

Hi Omar,

Did you check which process is using most of the memory? Please post the output of 'sh process memory | ex 0.00'.

#sh processes memory
Processor Pool Total: 886295488 Used: 339102192 Free: 547193296
lsmpi_io Pool Total: 6295128 Used: 6294296 Free: 832

On IOS XE, there are two memories: one is for linux kernel (lsmpi_io pool), and the other one is for IOS. As you can see you have a lot of free memory on the Processor pool which you will use for different processes. The other one (lsmpi_io pool) with very few free memory is expected to be as it is.

You can look at the following two posts on related topic:-
