Regarding your first question: I believe kern.ipc.nmbclusters controls what you want. This is a loader.conf tunable so you'll need to reboot. Network buffer tuning is documented, Section 11.13.2. Please read this before adjusting the tunable. http://www.freebsd.org/doc/en/books/handbook/configtuning-kernel-limits.html It would probably be more effective in the long run to find out why your mbuf count is so high and determine if said situation is caused by a problem with the NIC driver, or if there's something going on on your machine that's causing it. Regarding your 2nd question: not to my knowledge. -- | Jeremy Chadwick jdc@parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
