What I'd like to discuss:

1) Others that have had this same issue, and have applied the kernel update, did this fix your issues?

2) We have several other production host machines, and it's going to take a lot of moving things around before we can safely kernel update them.

It looks like the initial error is happening during pcompact defrag, which we see can be disabled as per https:// docs.openvz.org/openvz_command_line_reference.webhelp/_pcomp act_conf.html . Perhaps this would prevent the issue from happening if this were to be temporarily disabled until we can get the kernels updated. Or, perhaps we could disable pcompact altogether. Any thoughts or suggestions on this?
