If you have MAXUSERS set to 64 (which you should > probably do anyhow for servers), you will have a large number of mbufs. I have maxusers set at 64, which should give me 512 + 64 * 16 = 1536 mbufs, but that is apparently not enough. I made world yesterday and recompiled my kernel with NBUF set to 2048 and NMBCLUSTERS set to 8192. That ought to be enough (and with 128 MB of RAM, I'm not really short on memory) > You can use "netstat -m" to look at current usage, and the high-water I'll try that. -- Noone else has a .sig like this one.
