It hung up today and had to be rebooted. While checking /var/log/messages, I saw two instances of the following just before the system hung up.

Additional info:
-2163 just got pushed into the testing branch, which contains a lot of VM changes (It now matches mainline much more closely). If you could test with that, it would be appreciated.
Unfortunately, the server is my production server so I can't test with your testing kernels. I'll look forward to applying the updated kernel once it's officially released.
should be fixed in current updates.
Thanks for the bug report. However, Red Hat no longer maintains this version of the product. Please upgrade to the latest version and open a new bug if the problem persists.
