I am using gentoo kernel with openvz patches, vzmon module crashes, it
seems to be similar to that Proxmox 2.6.32 bug:

Switching to RHEL6-based kernel (or RHEL5-based kernel) is highly
recommended.

I have just checked and it looks like openvz-sources-2.6.32.49.6.ebuild
is the one carrying 042stab049.6.
