CentOS - Jan 2010 - Recent openvz kernels unstable?

Has anyone else running heavily loaded openvz boxes noticed strange behavior
with the latest kernels?  Ever since updating to the latest *.164* kernels, we
have mysterious machine lock ups.  Sometime there will be an oops message,
other times there will be none.  The oops messages aren't the same when we
manage to get one.  Sometimes a machine will just drop off network without
even a blip on the serial console.

I still have to try to get a memory dump from one of the machines to see if I
can find anything there, but I'm curious if anyone else has run into the
same
issues.

Never mind.  I remembered after I sent this that ovz-kernel isn't a centos
kernel, it just looks like one.  I also found
