I have seen this kind of crash with feisty's server kernel on my IBM x335 servers on a regular basis.
I would not be surprised if the initial cause(s) are in since 2.6.20 (which seem to have started the deep fall of kernel stability).
My problems vanished when I stepped back to edgy, in the meantime I have switched the host system to etch, while keeping the OpenVZ guests on feisty/gutsy.

I get the impression that the problem only occurs on SMP systems, and my systems crashed when LAN (wired GBit) and CPU and HD were under some load, e.g. 2 rsyncs over SSH over GBit. HD and LAN IO produce a large number of interrupts which seem not to be trivial to handle on a multicore system.
