Error description
The HBRC is executed at start up of IMS by a pre initialization call. HBRC and HBRD in COBOL program take no action to free shared memory. Shared Memory is freed via a termination procedure when IMS is shutdown because the connection remains open until IMS is quit, ODM resource manager termination code gets run. The issue is unlikely to be seen as it only occurs when a customer shuts down a busy server and fails over to a secondary server. In this unique case the termination manager malfunctions and attempts to free the memory of the a server twice.
