I'm having exactly the same issue. I recently migrated my AG server to a 
new machine with a Debian Squeeze (2.6.32-5-686). I can start the bridge 
without any problem. Here is the the 'ps' output:

1201      2146 11.0 10.5  49336 26712 ?        S    13:15   0:00 
/usr/bin/python /usr/bin/Bridge3.py --name=ES.USC --location=Spain 

But, same as Julian, the clients can only see the bridge the first few 
minutes after starting the bridge... I also get a new process running 
when this happens:

1201      2418  0.3  0.2   1736   640 ?        S    13:20   0:00 
/usr/bin/QuickBridge -g -m 10002 -u 51688 -i 600

At first i thought it was because i wasn't declaring some of the 
variables like the --registryurl but doing so doesn't help either.
I also tried running the bridge manually instead of running it as a 
service inside an script: Bridge3.py -n ES.USC -l Spain .

And last, i also made sure my server is using python2.5 as default 
instead of 2.6 if that helps with something.

Any help on this will be very much appreciated.
