Hello!

I have a 5.3 installation which currently has about 5000 'ESTABLISHED' TCP
connections.  That figure quadruples in the evening.

Are there any sysctls that I should be tweaking to handle lots of TCP
connections?

The machine is running pf -- is there some logging I could be doing to see if
pf is being overloaded?

Is there anything else I could be doing to see if some part of the OS is
failing to handle load?

Unfortunatly, I don't really have any concrete symptoms to suggest that the
networking part of this OS is overloaded.  Any suggestions for finding real
problems would be gratefully received :)
