[Parameter] smax [Default] max [Description] 
Retained connection pool entries above this limit are freed during certain operations if they have been unused for longer than the time to live, controlled by the ttl parameter. If the connection pool entry has an associated connection, it will be closed. This only needs to be modified from the default for special circumstances where connection pool entries and any associated connections which have exceeded the time to live need to be freed or closed more aggressively.
