Explanation
System management facilities (SMF) detected that
the SMF timer queue element (STQE) chain was in error.
A hexadecimal
reason code in register 15 explains the error: Code
Explanation
04
The forward pointer of an STQE contains zeroes. The system produces
an SVC dump, and SMF repairs the STQE chain.  Note: Repairing the
STQE chain results in the loss of some STQEs. Therefore, some tasks
no longer provide SMF interval recording.

08
The STQE chain points to an element that is not an STQE.  Note: Repairing
the STQE chain results in the loss of some STQEs. Therefore, some
tasks no longer provide SMF interval recording.

0C
The backward pointer of an STQE contains zeroes. The system produces
 an SVC dump, and SMF repairs the STQE chain. Note: Repairing the
STQE chain results in the loss of some STQEs. Therefore, some tasks
no longer provide SMF interval recording.

System action
The SMF timer program ends, and the system produces
an SVC dump.

Operator response
Notify the system programmer. You can re-establish
SMF interval recording for a specific task by restarting that task.
Consider restarting tasks for which SMF interval recording is required.
However, if you must re-establish SMF interval recording, but you
can't determine which tasks to restart, reIPL the system.

System programmer response
  Check error messages and the SVC
dump produced as a result of any previous abends. Check for any previous
abend code X'0C4' that might indicate a storage overlay has
occurred. If there is no previous abend code X'0C4', search
problem reporting databases for a fix for the problem. If no fix exists,
contact the IBM® Support Center.
