APAR status
Closed as program error.
Error description
Client receives a message asynchronously ( receive wait ) and backs out the transaction without processing the message. That is done for the same message several times in a short period of time. This may cause SIB to reorder the lock and unlock events for the message so that the message remains locked at the end.
