When the number of OfficeScan clients (including update agents) requesting updates from the OfficeScan server exceeds the server's available resources, the server moves the client update request into a queue and processes the requests when resources become available. After a client successfully updates components from the OfficeScan server, it notifies the server that the update is complete. Set the maximum number of minutes the OfficeScan server waits to receive an update notification from the client. Also set the maximum number of times the server tries to notify the client to perform an update and to apply new configuration settings. The server keeps trying only if it does not receive client notification.

When the OfficeScan server receives multiple requests from OfficeScan clients, such as a request to perform an update, the server handles as many requests as it can and puts the remaining requests in a buffer. The server then handles the requests saved in the buffer one at a time when resources become available. Specify the size of the buffer for events, such as client requests for updates, and for client log reporting.

The amount of network traffic varies throughout the day. To control the flow of network traffic to the OfficeScan server and to other update sources, specify the number of OfficeScan clients that can simultaneously update at any given time of the day.
