memory leak during installation

[Joyje]

When I try to install group-office locally inside a linux container, all RAM gets completely used up no matter how much RAM I let the container have access to.

The system doesn't completely freeze, but it takes almost a minute from the time I press a key on my keyboard until something actually happens on the screen.

This happens during installation after running apt-get install groupoffice when the "configuring groupoffice" step starts. Using flags --install-recommends or --no-install-recommends doesn't seem to change anything. The system still has the same issue, and the issue persists even after rebooting.

I'm using the PMG (Proxmox Mail Gateway) distro.
