Problem Note 57521: Connections to a load balanced workspace server fail, and the error "The Balance algorithm timed out before a server could be found" occurs
 |  |  |  |
When a client application attempts to connect to a load balanced workspace server that is configured for host authentication without providing host credentials, the launch of the workspace server fails. The following error associated with this type of launch failure is written to the object spawner log file:
In this scenario, the pending clients counter is incremented, but it is never decremented once the server fails to launch. If these launch failures continue to occur, the counter can increase to the point where new connections to the load balanced workspace server time out and fail. The following error is written to the object spawner log when this occurs:
There is no workaround.
This problem is fixed in the second maintenance release for SAS® 9.4 (TS1M2).
