A task that is critical to global resource processing ended due to an abnormal condition. The task either could not be reinstated or had reached the limit of reinstatement attempts allowed.
The system enters a non-restartable X'0A3' wait state.
Notify your system programmer.
Examine your system log for one or more instances of global resource serialization related failures (for example, SDUMPs) that occurred just prior to this failure. The task probably terminated as a result of these failures. Take a stand-alone dump of the system. Collect the available diagnostic data from these failures and contact the IBM® Support Center.
