Thought I'd repost this, and provide an update and see if anyone has any suggestions :)

After a 36 - 48hrs, the box will panic with "panic: pipeinit: cannot allocate pipe -- out of kvm -- code = 3". It doesn't seem to happen during periods of peak load, the last crash occurred at 3:45AM and there have been days when the box has made it through our peak load times with no

problems.

This happens because someone decided that it was a good idea to implement over-commit with pipes. Meaning that the storage required for a pipe's buffer won't be allocated until someone actually tries to write to it. If the space can't be allocated the system panics.

I'm working on a fix, should be available within a day or two.
