Explanation

The model of the tracked, persistent address spaces when compared to the request rate for each is lower than expected based on the previous history of each tracked address space. An unusually low enqueue request rate can indicate an impending system hang. The enqueue request rate is the ratio of the requests and the CPU used in the last collection interval. The next model will occur at nextmodeltime. The prediction used in the comparison was modeled at lastsuccmodeltime.

System action

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.

Operator response

Examine data from Runtime Diagnostics to determine the source of the lower than expected enqueue request rate.

System programmer response

See operator response to determine the cause of the lower than expected enqueue request rate.

Problem determination

The enqueue request rate for one or more persistent address spaces
is lower than expected and may indicate a system problem.
