How to stop the DEBUG info in Syso?

Probably a very silly question.

Either the ExternalComponentManager or the AbstractComponent (I don’t really know which one) is giving me loads of DEBUG info in System.out:

2011-04-01 20:21:17,752 [pool-2-thread-1] DEBUG ch.usi.inf - (serving component 'component') Processing IQ (packetId 380-11).
2011-04-01 20:21:17,754 [pool-2-thread-1] DEBUG ch.usi.inf - (serving component 'component') Processing IQ request (packetId 380-11).
2011-04-01 20:21:30,321 [pool-2-thread-2] DEBUG ch.usi.inf - (serving component 'component') Processing IQ (packetId 49wSM-184).
2011-04-01 20:21:30,321 [pool-2-thread-2] DEBUG ch.usi.inf - (serving component 'component') Processing IQ request (packetId 49wSM-184).

How do you make it less verbose?

Thanks,
