This Natural profile parameter specifies the time a Natural/HA process that is running on a backend server should live after having served a request for a particular Natural/HA session. If, during this lingering time, the next request for this session is issued to the same backend server, the lingering Natural/HA process can immediately serve that request without a new Natural/HA process having to be started, thus improving Natural/HA application responsiveness.

Possible settings	1 - 32767	Natural/HA processes linger for the specified number of seconds.
	0	Natural/HA processes do not linger.
Default setting	0
Dynamic specification	yes
Specification within session	no

Notes:

1. The setting only applies to Natural running in an HA (High Availability) environment.
2. This performance optimization depends on the load balancer forwarding consecutive requests for a particular Natural/HA session to the same backend server. This can be the case if either “sticky” sessions are explicitly configured, or if the load balancer implicitly is switching relatively infrequently to a different backend server for a particular Natural/HA session. If, on the other hand, the load balancer is balancing the individual requests (e.g., by forwarding them to a different backend server on a round-robin basis), then this parameter has no beneficial effect.
3. Natural/HA processes do not consume CPU resources while lingering.
