Explanation

The dependent region was placed in a wait state by DFSQSPC0, the IBM® IMS Queue Control Facility for z/OS® version of the Queue Space Notification Exit. The wait state occurred based on IMS queue usage, which exceeded the user or default limits. As a result of the wait state, the wait queue went from empty to queued requests, resulting in this message.
