>Description:
	I am using the snapshot on 19 Nov, I am not sure is the pf or it is
	the kernel problem, the system seems hang, and all ports got filtered.
	The firewall rules is ok, it can filter IP/ports I don't want, and open
	ports what I want, after 10-15 hours running, the system hang, but not
	fully hanged, I mean, I can still ping the system, when I try to connect
	to the system, it just stay at "connected", and no any responese, I do
	a nmap to the system, all ports are "filtered". I also try to disable the
	PF, the problem still happen too.

	I have setup a cronjob, it will touch a file every ten minutes, when the
	problem happen again, the cronjob stop too.  I checked with the log files
	after reboot, nothing special, it is interesting..

	Please tell me if anything I can test for figure out the bug.

>How-To-Repeat:
	No, I try to disable the PF, or update with newest snapshots, it happend
	again too.
