[Discuss-gnuradio] Error mensage 0000000

[Jose Marcelo Lima Duarte]

Some time when running a program developed with gnuradio, a sequence of zero 
appear on the prompt. Does it mean that some block is overrunning, not 
handling all the information gived to him?
 
What happen in this case? The data will accumulate on the memory for a latter 
process or it is lost?

There is some easy way to know which block is causing the overrun?

Thanks for your attention.
