Error in writeBlock - could not write 131063

[srekant]

Hi,

I getting the below errors when running job(processing 5 million records) in DataStage 7.5.1A on GRID Production Environment:

Unexpected termination by Unix signal 10(SIGBUS)
Error in writeBlock - could not write 131063.

When i restart from this job alone in the sequence job executes to completion.

stages used in the job are:
Datasets(input and output)
Join,
Transformers,
sorter,
Lkp,
and Filter

Any suggestions on what the error is and how to avoid it in future.
