Error description
Error DescriptionÏ CHIN ABEND 878-10 BECAUSE SUBPOOL 0, KEY 8 IS FILLED WITH XSTBs, The chinit trace shows the rriAccept block is not being correctly freed, leading to a build up of these blocks over time. Eventually this can lead to storage exhaustion in the chinit address space, particularly when running with a small REGION size. It appears that the fix for PK90638, which addressed this in an earlier release, has been regressed as a result of changes in this area at 710

If an error occurs while the channel is still binding (for example, an attempt to start an unknown channel) this storage is not freed.
