I am trying to understand why my memory is at > 90%
16gig of memory is in my system, 4 gig is been used by a VM. 
I am not sure if it has to do with upgrade to 6.9.2, or the fact I needed to upgrade all my dockers apps also. 

Would appreciate if someone could help me find out what is the problem.

Did you reinstall or change any of them?

 

Docker containers will write into RAM if their container paths are not mapped to actual storage on the host (subfolders of /mnt).

Also, why is your docker.img 100G? 20G is usually more than enough. Have you had problems filling it? The usual reason for filling docker.img is an application writing to a path that isn't mapped. Any path specified by an application must correspond to a container path in the mappings, and Linux is case-sensitive.

 

And your appdata, system and (in your case) VM Images shares have files on the array, in fact, appdata and system are set to not even use cache. That isn't critical, but it will keep array disks spunup since these files are always open, and docker/VM performance will be impacted by slower parity.

Since you have some other things about your docker configuration that seem less than ideal, maybe even if you didn't reinstall or change anything, it was already not working correctly.

I am using mostly of my dockers to download content. I did have problems in the past, that is also the reason of the 100gb image. I will check every given folder of my dockers,but i am sure this was not an issue before the update. Shouldn't my mem go down when i disable dockers completely in the settings?
Doesn't happen.

How would you advice me to setup my system ? I could use i little bit of knowledge.

No you would have to reboot to get that RAM cleared.

update will not cause this.

Thanks for the support. 
After reboot and disabling dockers, saw that the memory was not high anymore.

I moved al my system ,appdata and vm depended files to the cache (unbalance). 

Shrinked the dockers image to 25GB (disable/delete/create new from template)
Checked every given folder in dockers that it points to /mnt/user/*
It now works like a dream 

Should I move the dockers image also to the cache or is that not necessary ?

you definitely want the docker.img file on the cache (or a pool) for performance reasons.   That is normally stored in the ‘system’ share which you say is already on the cache so nothing to do if that is the case
