This is a shot in the dark, but is there a chance that you're on a PPPoE
(or similar) connection, even with a statically assigned IP? Is there a
chance that your connection becomes dormant enough for your ISP to time
out your connection, obligating you to "re-dial"?

The answers to your questions are:
Strictly it is not a hang as the system does not freeze, it largely functions
normally, just loses Internet transparency.
LAN functions normally, DHCP on the LAN, and the pfSense webGUI functions normally, can read logs, reboot from this etc. Reloading
the filters functions as one would expect, however the connection is not established.
The System Overview readings appear normal, states is now currently 110.
The LAN and WAN graphs appear the same as when it is functioning normally.
If there was a worm sending out screeds I would hope I'd be aware if it.
WAN is statically assigned an Internet address.
Modem links lights remain up and the modem continues to function normally. One can replace pfSense and connect a notebook PC Card
NIC, configured with the Static IP and resume Internet access, proving the modem has not failed.
I can ping the LAN nic but can't ping my ISP thru pfSense, although I can when
I reboot and it is again normally functioning.
Essentially it appears to be functioning normally, except the connection through stops / disappears! Everyone on the LAN loses
Internet connectivity.
Anything else I can advise I'll be delighted to do so, although it might be
when it next happens.
Kind regards
David Hingston

Gosh, thats got to presumably use more than the default of 10,000!
Currently there are 116 there.
Easier than you might think. If you have a worm infected laptop plugged
into your network only periodically it can cause state table exhaustion
and the type of symptoms you describe. It wouldn't be (even close to)
the first time I've seen that.
When it "hangs", what exactly do you mean? There are tons of
possibilities for "hangs". Does it become completely non-responsive,
console dead and all? Does the console work but it falls off the network
completely? Is the LAN still up and the webGUI functional but Internet
just doesn't work? If that's the case, you said cable modem, I presume
that's DHCP, do you have a valid WAN IP when it happens? Do you have
link light on WAN? Are all the lights on your cable modem normal? Can
you ping your default gateway? etc. etc. etc.
Be as specific as you can be, the details you gave lead to a lot of
questions and not a lot of specific recommendations.
