I'll add my $0.02: About the only thing which I have run across which I regularly run into problems with are TCP/IP buffer parameters such as mbufs. If I tune my kernel so I can get insane flows across the internet (DS-3/OC-3 level links), I will quickly run out of buffers if I get more than a couple of flows going. I would *love* to see these dynamically sized - the buffer space, not necessarily the tcp/ip tuning parameters. I would also like a warning if they go above a certain level, and perhaps a configurable hard limit if necessary. - Forrest W.
