I'm running a Wrap 1C-3 and am also experiencing hard locks after 1.2b3 
upgrade. I have since reverted to 1.2b2. Oddly enough, the behavior 
seemed to be exacerbated by the packet shaper. I run the packet shaper 
with rules, to make Azureus bittorrent traffic lowest priority, and 
while bittorrent was running, if any other heavy traffic occurred, the 
router would lock up solid. No ping, console dead. I have the router 
syslogging to another box, and there's absolutely no notice that it's 
about to break. The only things in common with each lockup is this. When 
running World of Warcraft, with bittorrents running on two different 
computers behing the wrap monowall, the router would lockup within 10-15 
min every time. If I turned off the packet shaping, then it would take 
longer to freeze up but it would still freeze. Messing with settings in 
the router via the web page, such as monitoring bandwidth usesage or 
watching the log would also cause it to lock up faster.

I noticed 25-30 port bounces on 38860 and 38866 before each crash while 
bittorrent was running, but I assume this is because most torrent 
clients use random ports, while azureus just uses one.

There's no science behind this analysis of the lockups, just 
observations. I reverted to 1.2b2 and the lockups went away. Been 
running rock solid for 2 days now. Previously, I had a 22 day uptime 
between power outages on the router.
