Problem Note 47326: Host machines within a load-balanced cluster are not used
 |  |  |  |  |
The load-balancing process keeps an internal counter, by host, of how many client machines are pending redirection to that host. When a load-balanced workspace server or a pooled workspace server is requested, this count is incremented. However, the count is not decremented when the server fails to start. As a result, the pending count becomes abnormally large and prevents the host from being used in the load-balancing process.
There is no workaround or solution for this problem.

An internal counter that is not decremented when a launch failure occurs can cause a host to appear, incorrectly, as being busy. As a result, the load balancer does not redirect requests to that host by load balancing.
