Why does the error SIGBUS occur? There is a job in which I am retrieving data from a table and performing a lookup against a dataset. The dataset has some 16million plus records. I am using a lookup stage for this. When I run the job, it retrieves the data from the table. While fetching the records from the dataset it aborts after reading some 15.9 million records giving SIGBUS error.

A SIGBUS error is simply a bus error. It could mean a hardware / memory problem or could indicate a problem in the software. I'd start by opening a case with Ascential Support to see if they've seen these errors before. Or possibly have a chat with your SAs.
