For the persistent address spaces that are not being tracked individually, the model of the persistent address spaces when compared to the average arrival rate for the group is higher than expected. An unusually high SMF arrival rate can indicate a series of recurring failures for the address space which can lead to a system hang or may be indicative of a damaged system. The SMF arrival rate is the ratio of the arrivals and the CPU used in the last collection interval. The next model will occur at nextmodeltime. The predictions used in the comparison were modeled at lastsuccmodeltime.
The WTOTYPE of the check has been changed to NONE so that subsequent runs of this check will not produce an operator message until new data is available. The check will collect data and model new predictions at the next collection interval. After modeling is successful, if the current setting of WTOTYPE is still NONE, the previous setting will be restored so that the check will issue future exceptions based on that setting.
Examine SMF arrivals to determine the source of the higher than expected arrival rate.
See operator response to determine the cause of the higher than expected SMF arrival rate.

This message should trigger an alert to system programmers / operator to determine the cause of the high SMF arrival rate.
None.
The SMF arrival rate for one or more persistent address spaces
is higher than expected and may indicate a system problem.
