(FOC198) FATAL ERROR IN DATABASE I/O. FOCUS TERMINATING

All,

I am facing the following abend in one of the FOCUS jobs in production.

(FOC198) FATAL ERROR IN DATABASE I/O. FOCUS TERMINATING

The job has been running fine for ages, but now one of the input file has more data and I suspect that is the reason for the abend.

Can any one please provide some pointers to solve this abend.
