Depending on considerations such as the capacity of a physical server, you can specify a limit on the maximum number of client connections made to any service. If you have set such a limit on a service, the NetScaler appliance stops sending requests to the service when the threshold is reached and resumes sending connections to the service after the number of existing connections falls to within the limits. You can configure the NetScaler to skip this check when it sends monitor-probe connections to a service.
At the command prompt, type:
set lb parameter -monitorSkipMaxClient enabled
