You cannot use the application object server (AOS) loadbalancer to load balance for a golive AOS in Microsoft Dynamics AX 2012 R2 Go Live

This article applies to Microsoft Dynamics AX for all regions.


You cannot use the application object server (AOS) loadbalancer to load balance for a golive AOS in Microsoft Dynamics AX 2012 R2 Go Live. Additionally, all user connections use the AOS, and the system performance goes down significantly.


This problem occurs because the workload value in the SysServerSessions table keeps going down to a lower negative after you log clients on and off the AOS for several times.
