This configuration parameter specifies the number of backlog connections to maintain when all threads are busy. Through operating system services, the agent maintains a queue of pending connection requests that are received from the processes that need the services of the agent. This configuration parameter controls the maximum number of pending requests to hold in the queue.
Decreasing the value of this parameter may prevent processes from performing tasks that require adclient services, for example, a login request may be unable to authenticate a user. Increasing the value of this parameter may reduce the chance of service request failure, but may waste system memory resources and impact system performance.
If you change this parameter, you must restart the adclient process for the change take effect.
