Comment 31 for bug 1178707

That "kernel BUG" probably does not mean that much. Given there seems to be at least one (but likely more) page on the free list which is not really released, this will result in more and more fallout. Is it possible to elaborate more on disk and network setup (at least anything that differers to an instance one would get by default)?

The stack traces here do not help much to find out the problem. Rather this requires to understand the setup and possibly think of something that this would exercise more than other environments.
