Host selection
When a client connects to a relay server, the relay server attempts to start a session on the dependent host that has the lowest number of running sessions as a percentage of the maximum number of sessions allowed for the host.
If the session fails to start on the selected host, the relay server successively attempts to start the session on other available hosts until it finds one that can support the session. If there are no available hosts (if the number of running sessions on All Hosts equals the maximum number allowed), the following message appears.
Otherwise, if the session cannot be started on any of the available hosts, the following message appears.
In a relay server setting, FH Web Edition checks the maximum sessions settings on the relay server and its dependent hosts. The maximum sessions value on the relay server is the maximum number of sessions that can be run concurrently on all dependent hosts assigned to that relay server. To modify the maximum sessions on this host, on the host, open the FH Web Edition Connection Manager, and then choose Host Options → Session Startup.
