Re: Packet loss every 30.999 seconds



Try it with "find / -type f >/dev/null" to duplicate the problem almost
instantly.

FreeBSD used to have some code that would cause vnodes with no cached
pages to be recycled quickly (which would have made a simple find
ineffective without reading the files at least a little bit). I guess
that got removed when the size of the vnode pool was dramatically
increased.
