What kernel revision are you running? I know some of the 2.0.3X kernels
pre .36 supposedly have a problem with never dropping connections. So,
even though the client side has dropped, the server keeps it alive, and
this is counted in tcp servers max. Here's an example:
tcp 32696 645 ns1.netmdc.com:17117 pm3-1.netmdc.com:telnet
FIN_WAIT1
tcp 32696 555 ns1.netmdc.com:17162 pm3-1.netmdc.com:telnet
FIN_WAIT1
tcp 32696 675 ns1.netmdc.com:25151 pm3-1.netmdc.com:telnet
FIN_WAIT1
tcp 32216 638 ns1.netmdc.com:25351 pm3-1.netmdc.com:telnet
FIN_WAIT1
tcp 32696 670 ns1.netmdc.com:26194 pm3-1.netmdc.com:telnet
FIN_WAIT1
tcp 32696 625 ns1.netmdc.com:14393 pm3-1.netmdc.com:telnet
FIN_WAIT1
tcp 32696 625 ns1.netmdc.com:16940 pm3-1.netmdc.com:telnet
FIN_WAIT1
tcp 32696 630 ns1.netmdc.com:16948 pm3-1.netmdc.com:telnet
FIN_WAIT1
tcp 32696 615 ns1.netmdc.com:17031 pm3-1.netmdc.com:telnet
FIN_WAIT1
tcp 32696 689 ns1.netmdc.com:17204 pm3-1.netmdc.com:telnet
FIN_WAIT1
tcp 32696 615 ns1.netmdc.com:17531 pm3-1.netmdc.com:telnet
FIN_WAIT1
tcp 32696 576 ns1.netmdc.com:18093 pm3-1.netmdc.com:telnet
FIN_WAIT1
tcp 0 14706 ns1.netmdc.com:telnet byu006601wks.rn.b:61165
ESTABLISHED
tcp 19 0 ns1.netmdc.com:5299 pm2-4.netmdc.com:telnet
CLOSE_WAIT
This happened when i had to reboot the portmaster, the connections never
cleaned up properly. This was WELL over a week ago ;)
