N3T_Appl_Reject_Conn

Requests for new connections are not satisfied by this application because the connection backlog limit has been exceeded. A server application workload spike or a server system resource constraint likely caused the z/OS application to be unable to complete the workload.

This situation occurs when, for one interval, the active connections value is between 80% and 90% of the connection high water mark and the backlog connections rejected value is greater than zero.

Possible solutions include:

Formula: Percent Active Connections >= 80 AND Percent Active Connections <= 90 AND Backlog Connections Rejected > 0
