Note that if we implement a 'fair share' buffering scheme we would never get a failure, which would be a good thing. Unfortuantely fair share is relatively complicated. > (Plus, just setting a threshold is not good, you also want > some histeresys, because you can easily conceive a system that > runs at XX % mbuf occupation, whatever XX you pick.) With fair share or some other type of setup I would agree. Given our current 'things fail badly if you run out' I think a warning at 90% or 200 left, or something would be a real good idea. With the current allocation scheme this is on par with "/foo file system is full" messages, we should have a "networking stack is full, build a kernel with more mbuf's message". -- Leo Bicknell - [EMAIL PROTECTED] - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/ Read TMBG List - [EMAIL PROTECTED], www.tmbg.org To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
