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. -Alfred To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
