Hi Maiko,

I can't recall the exact moment that message started to appear here, but 
it seems that it is somehow connected with sending beacons, i.e. when it 
sends a beacon, every ten mins or so, another message appears. In 
addition, when there is an active forwarding session in place, after 
every 5-6 of usual lines with "New mail for ...", there is another 
couple of "timer: ints were off!".

Well, I am concerned myself too much, because it seems that after a day 
of JNOS running (maybe a bit more, maybe less) - its memory goes too 
low, according to the information in the upper left corner, so JNOS 
stops with proper operation (sending beacons, accepting incoming 
forwarding attempts etc), so the system has to be re-booted. Looks that 
low memory started to appear in the same time with "timer: ints were off!".
