Message; "op_prt_buf, print new page fa".
Have you changed the code for these jobs in the past week? If not, check for ERROR/WARNING/MESSAGE statements that might be executing when the ALTERNATE IMAGE NUMBER is zero. (This could cause this error to appear despite the jobs running fine for months – it might be the first time a particular error/warning/message occurred on a particular record). Also, check for ERROR/WARNING/MESSAGE statements that might be in End of Process or an unbounded range end frame.
Another likely scenario is that more ERROR/WARNING/MESSAGE statements are being triggered for a record than there is room for on the page -- to check for this, comment out your ERROR/WARNING/MESSAGE statements and run the job, and see if the error occurs.
If you check for all of the above and none of those seem to be the cause, and you are using standard page headers in those output processes, try turning off the standard page headers, and run one of the jobs, and see if that fixes it.
