Hi Alden,

When executing "show meminfo" command, can you also check the Buffers and Cached memory? You should also see them in the output of the above command.

The Buffers and Cached Memory can also be considered as Free Memory and both can be reclaimed anytime memory becomes low.

I feel above could be the reason why you are seeing High memory usage. I will try to see if I can find the article which is written on this topic.

Regards,
Rahul

Hi Rahul, thanks for your response

When I use the "show meminfo" command that's all I see and I can't see any more options

vSZ-HNI# show meminfo

vSZ-HNI# show meminfo
Total Memory: 12.7 GB
Used Memory: 11.5 GB
Free Memory: 1.3 GB

you can get more info about memory, disk and cpu usage from the cli below:

show control-plane-stats controller1-C type memory period 7-d

show control-plane-stats controller1-C type, after typing this command, you can select memory, disk or cpu depending on your needs.

So how do I solve this? I always need to restart VSZ, is there no other way to solve this?
