Hi Detlef,
propably, this might be a problem with sporadic interrupts mentioned in 
the LPC22xx user's manual. Have you set up the default interrupt 
handler?  If not, just define an empty interrupt routine and assign it 
to the default interrupt address. This will catch every sporadic 
interrupt and your system keeps running.
