For instructions on configuring an application pool to recycle at a scheduled time, refer to the Microsoft TechNet Library at https://technet.microsoft.com/en-us/. Ensure that the times you set do not coincide with the Start of Day (SOD) or periods of peak sales activity. If you configure the application pool to recycle at a scheduled time using the IIS Manager, consider the following recycle settings for the IIS Application Pools.
Set the Memory Based Maximums to less than half of the available server memory.
Set the .NET Integration mode to Classic for the CAPS Application Pool.
Set the Disable Overlapped Recycle setting to True for the CAPS Application Pool.
Leave the Application Pool’s Pipeline mode settings on the default settings.
