Error description
Storage for subpool PGCSDB in GCDSA (above the bar) is accummulating for some events defined as transactional. If the transaction commits backwards, the event is not emitted for that task and the channel and container storage is not being freed correctly. Over time, this leads to a large build up of channel and container storage in the PGCSDB subpool. . If the transaction commits forwards, the event is emitted and the container is deleted as expected. .

Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: Storage leak of above the bar storage * * when transactional events are used. * **************************************************************** A CICS region is experiencing storage leak in the PGCSDB subpool. CICS is using transactional events but these are never transmitted for tasks which commit backwards. As a result channel storage associated with the event is not freed, leading to storage creep in the PGCSDB subpool.
Problem conclusion
DFHEPEV has been changed so that channel storage associated with transactional events which are never transmitted is always freed.
