1.1.4 stops responding to requests

Interesting... I've been seeing exactly this happening on our own system. In 
our case, I could track it down to the fact that it stopped responding 
shortly after accounting packets came in. Turning off accounting (already on 
NAS level) deterministically solved the problem for me, so I suspect the 
problem to be somewhere near there.
I never followed this trace, because accounting is optional at our site (free 
wireless) and it was our prod environment, I didn't want to mess around 
without a good reason. So accounting is just off at the moment.

Is it an option to not do accounting? Or maybe queue the acct in files rather 
than a proper backend (for me, the issue happened in combination with mysql). 
I never tried if the hangs occur also when logging to a file.
