Thanks for your comments. It's not the first time I experienced oddities with the Debian OpenVZ kernel. I'll definitely check out the RHEL6 kernel. Also, knowing that what I reported is _not_ expected behavior is valuable for me to know. I started to think that I might have misconfigured the CTs due to a lack of understanding the mem limits/guarantees.
