I did a fresh install yesterday of FreeBSD-2.2.7 on an Intel PR440FX-based computer (PPro180, onboard AIC7880, onboard Intel EtherExpress Pro 100B, 128MB RAM). The installation is pretty minimal; there isn't a whole lot running, there's virtually no load on the box, and I'm the only one connected. netstat -m produces the following (booting from kernel.GENERIC): 75 mbufs in use: 66 mbufs allocated to data 1 mbufs allocated to packet headers 7 mbufs allocated to protocol control blocks 1 mbufs allocated to socket names and addresses 64/66 mbuf clusters in use 141 Kbytes allocated to network (97% in use) 0 requests for memory denied 0 requests for memory delayed 0 calls to protocol drain routines The 64/66 mbuf clusters in use concerns me. Why would a completely unloaded box with a plain vanilla installation show this? I compiled a bunch of different kernels with various values for maxusers and NMBCLUSTERS, and the output of netstat -m was pretty much as above, even with wildly different maxusers and NMBCLUSTERS. Does anyone know what's happening here? Is the kernel broken? Is netstat broken? Is there something I should check? Do I not know what the hell I'm talking about? Thanks in advance!
