I have noticed with running VM’s inside of Univention, when the VM shuts down, the memory allocation isn’t released. I shut down VM #1 which had a 6gb allocation, and even an hour later, that 6gb had not been released back to the linux system for use. Tried restart libvert, but that did not help - wound up having to restart the system. Has anyone else ran into this?
Sorry for the lateness of my reply - back on this project some now - I checked via Top and free -mh - Cached AM is what was concerning me - I cleared it of course with - # sync; echo 1 > /proc/sys/vm/drop_caches
