I see a few occasions of your ethernet link flapping, could be a modem
rebooting or something else, bad cable, maybe.

i did notice that, yeah. this interface is directly connected to an ont, powered locally. i'm reasonably certain the other side of the link isn't flapping and that the cable is ok. to corroborate this, until recently beginning to experiment with pfsense, i'd been using another computer running linux/iptables, and hadn't seen any such symptoms while using it.

in system.log, it seems that the flapping occurs as a result of check_reload_status:

[as a momentary stopgap, i've manually assigned the address given to the interface via dhcp]

what is check_reload_status, and why does it cause this behavior? i don't see this happening for the lan interface [msk0] - only the wan interface.
