I'm working on m0n0wall 1.2b7, and I'm experiencing problems with xml config 
file. 

Sometimes (I can't establish exactly when and I can't reproduce it) the 
config.xml file get truncated; the amount of lost data may vary. 

I'm using it with heavy load, but because of some "minor" customization I 
don't want to upgrade system to 1.2b9 version. 

The only try I did was to extend the timeout of config_lock procedure: in 
file config.inc, row 535, I changed "sleep(1)" to "sleep(3)", but 
truncations even occurs. 

If someone experienced similar problem or has some suggestion I would 
appreciate. 

Thanks,
Marco Gambardella
