Error description
MSGIEC0036I and ABENDS002 when processing an IMS PI Extract. Due to a Knowledge Module (KM) formatting issue during Extract processing, storage immediately following a buffer used to hold field metadata may be overwritten, resulting in various issues including ABEND S002-04 IEC036I in subsequent Extract dataset processing. Error message for this one instance appears as: IEC036I 002-04,IGC0005E,jobname,stepname,ddname,volume,dsname

Problem conclusion
1. IMS x'27' Database Extension record KM did not cater for a DBXVSI segment length value of zero, which caused the segment data to be repeatedly output until an internal MAXFLDS value was encountered. This results in error ALZ0051E being issued in Online Browse, but not in Batch processing. The KM is corrected to format a single DBXVSI segment where the segment length value is zero. 2. An internal buffer is created to store field metadata, the number of field entries allowed is defined by an internal value MAXFLDS. When MAXFLDS is reached the prefix area of the next field entry is being cleared, resulting in storage beyond the field buffer being overwritten, which can lead to unpredictable results. This scenario is now corrected.
