High used and cached memory

Hello there!!

I've got a question, is this a normal behaviour of the memory management from the router:

My concern is that it says 77% is available but at the same time says 94% is used... maybe is the cached memory? and why is so high?

Yes thats normal, the cache will eat-up memory if used and will be freed automatically if system memory is needed/allocated again.

You can flush the cache via this command and if you encounter problems or add it as a scheduled routine command, but you should not need to.
