Just a quick hint for those running Lotus Notes Travel(l)er. When you try to restart the HTTP task on the Domino, you have to stop Travel(l)er prior to restarting the HTTP task ( restart task HTTP )
Otherwise you will see the following message on the server console
and the HTTP task will not restart.
UPDATE: The problem does not occur when you type “tell http quit” followed by “load http” at the server console.
