Application backlog connections rejected

Application backlog connections rejected is the sum of the connections that the TCP/IP stack is rejecting because the connection backlog limit for the application has been exceeded. Acceptable levels can be determined in relation to service level requirements. Backlog connections rejected can affect application availability and lead to violations of service level agreements. This could be due to too many connections arriving or because the application stops accepting connections. Increasing the backlog limit and load balancing are possible solutions.
