Error description
After a shared receiver channel fails, because the CHIN and QMGR is terminated, shared channel recovery attempts to restart the shared channel by another CHINIT in the QSG, but it receives message: +CSQX479E CSQ1 CSQXRESP Channel yyyyyyy.CSQG.00 is active on active on CSQ2, shared channel adoption failed.

Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 8 * * Release 0 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: Shared receiver channel fails to start * * with CSQX479E CHANNEL ADOPTION FAILED. * **************************************************************** * RECOMMENDATION: * **************************************************************** A shared receiver channel was running on a chinit which subsequently terminated. The channel was restarted and attempted to connect to a chinit that was still active. This detected the orphaned shared status entry and attempted to adopt the channel. rriAdoptSharedMCA checked the user data for the stopped chinit to determine if the channel could still be running on the owning chinit, however an error in this check caused it to incorrectly determine the channel could be running. As a result the adoption process attempted to send the stopped chinit a message requesting it end the channel. As the original chinit was still not running no response was received for this request, and channel adoption failed.
Problem conclusion
Channel adoption processing has been changed to correctly check the state of the qmgr and chinit where the channel was running previously, ensuring that a message to kill the channel is sent if the owning qmgr/chinit are running and able to process the message. 000Y CSQXRCSI
