Michal, this was printing so many debug messages to console that the whole server hangs and i had to hard reset it after several minutes :( Sorry but i cannot test such a things in production. There's no problem with one soft reset which takes 4 minutes but this hard reset creates about 20 minutes outage (mainly cos of disk quotas checking).
