Error description
ABEND04E RC00E2000F is the result of overusing storage in DSNXOQSJ. It used a query block that is larger than obtained and incurred storage overlay. It was found that DSNXOQSJ adds an entry for COLUSE array without checking current usage. In this PMR, DSNXOQSJ at offset +5E1A obtained COLUSEs for 255 entries, then used 407 entries and caused overlay.
