In my company. About twenty of 686 FreeBSD 2.2.1 Machine is connected
via FastEthernet.(Intel EtherExpress)
Hub is SMC tigerstack.(not a switching)
Problem occurs in the same way when I used SMC 9332BDT.
Network options MAXMEM=262144
Concurrent User is aboue 230 per machine.

conection is closed.
vnode, file table, mbuf, somaxconn is sufficient.
kernel configuration is

options MAXMEM=262144
maxusers 250
options NMBCLUSTERS=8192
options CHILD_MAX=3500
options "FD_SETSIZE=2048"
.....
