[Bridge] br: memory squeeze!

[TC Hough]

I set up a bridge for my network and I'm having some trouble.  At first 
everything worked great, but after about 3 days of continuous bridging, 
my bridge machine died.  Approximately once a second, the message: "br: 
memory squeeze!" would appear on the console.  Keyboard input was mostly 
frozen, as well.  I could switch virtual consoles, but I couldn't type.  
No traffic would pass through the bridge.  When I rebooted, everything 
seemed fine.

I don't have a whole lot of memory on the bridge machine, but I feel 
like it should be sufficient, since bridging is all it ever does and I 
have plenty of swap space.  The system log doesn't should anything I 
thought to be abnormal.  The memory squeeze messages were not logged.  
Here's the output of /proc/meminfo:

Any suggestions?
