Fatal Error:- buffer(0),0: Fatal Error: APT_BufferOperator

[prasson_ibm]

Hi,
I am getting following fatal error during job run:-

buffer(0),0: Fatal Error: APT_BufferOperator::writeAllData() write failed. This is probably due to a downstream operator failure.
My job design is like this:-

Sequential_file----->Funnle Stage-->transformer--->db2 stage
I think there is a problem with funnel stage......If it is true ...plz tell me how i can reslove this issue and why i m getting this problem..???

Look at the job score and find where the buffer operator was inserted. My guess would be on the inputs to the Funnel stage. Start your diagnosis based on what you find in the score.
