Other abends are also possible as there are 2 byte or 6 byte shift in the shared private storage above the bar (SCLASS 21 ) .

A client can only send 32 statements chained together. If the client sends more than 32 statements in a chain, the DB2 server detects a DRDA exception but it also incorrectly processes each statement without initializing its internal loop counter thereby leading to a storage overlay. The storage overlay may lead to unpredictable results including one or more of the reported abends.
Problem conclusion
DB2 server processing has been changed to not process the statements after detecting the DRDA exception error.
