Default OpenBSD keeps locking up/crashing

Hi There
I'm still using 4.8-stable with a GENERIC kernel. I'm gonna do a fresh install of 5.0 soon rather than upgrade twice(I'm using it for such a simple purpose that it will be quicker that way).
Anyway i thought i'd make sure that i didn't have a misconfiguration first, to save time in future.
I'm just using this OpenBSD to separate a few servers from an internal subnet. So OpenBSD just has 2 NICs. One attached to a switch, that the servers and Internet gateway are attached to and one attached to a swith that the internal clients are attached to.
Anyway quite often network connectivity goes down for the internal clients. The only system that is noticably causing this is the afore mentioned OpenBSD firewall/router. By noticable i mean that the console won't accept or echo characters from the keyboard.
This box is the default install of 4.8. The only alterations i've made to it are disabling password authentication on ssh, enabling routing and configuring pf. Oh and i brought it up to the latest stable/patch version a few times, following exactly the method in the FAQ. It does run O.K. It just crashes/locks up about once a day on average.
The output of:
Code:
# df -h
reports that the fullest filesystem is /usr/obj at 48%.
I'm really puzzled. I know it is extremely unlikely to have been hacked, if this is even possible at all. Also the Internet gateway doesn't crash hhmmm.
Also i couldn't find anything in the mail or logs relating to anything like what's been going on. But i didn't untar the old logs. I'll post pf.conf if you realy think that firewall rules can cause an OpenBSD system to crash?. Sorry that's not much data to go on. The main question is can a misconfigured pf cause peroidic system outages?. If so could you advise me on pf if i post my pf.conf?
Thank you very much for your time
regards unixjingleman
