Wow, thank you Gena! That clears things up. Now it's time to write a
check for open files and figure this out...
Thanks,
Chris

It works with running containers too.
pcompact do nothing if threshold is not exceeded.

!!! you have used 101G inside container.
after stop container - free space is changed to 57G
threshold is exceeded, and pcompact start to work.

So I guess my question is am I expect to /stop/ and compact my
containers regularly?
You have 44G *DELETED* *OPEN* files inside contaier.
This is not normal situation.
If you can't prevent such deleted but still open files -
you have only one way: restart containers (by cron?)
and run pcompact by cron after restarting containers.
Better way - prevent deleted but still open files
inside your containers, and use pcompact on running containers.
P.S.
Try to set THRESHOLD=1 in /etc/vz/pcompact.conf for better compacting.
