Problems with batch jobs

Not enough records read or too many records lost: If the job summary log (JOBSUMDD) indicates these problems, your batch job might not have sufficient priority. See the recommendation in Collecting data by using the batch JCL for details.
Abend B37 (out of space) when creating reports or bpd files: Buffer Pool Analyzer cannot store temporary data in a temporary work data set because of virtual storage constraints. Use the BPWORK DD statement as described in Specifying a JCL command stream.
FPEU0020E or FPEC4085U insufficient virtual storage: Check the REGION statement in the affected batch job.
