When the process is stopping, the server resolutions are suspended. However the task is still periodically woken up for nothing. If there is a huge number of resolution, it may lead to a noticeable CPU consumption for no reason. To avoid this extra CPU cost, we stop to schedule the the resolution tasks during the stopping stage. Of course, it is only true for server resolutinos. Dynamic ones, via do-resolve actions, are not concerned. These ones must still be triggered during stopping stage. Concretly, during the stopping stage, the resolvers task is no longer scheduled if there is no running resolutions. In this case, if a do-resolve action is evaluated, the task is woken up. This patch should partially solve the issue #2145.
