Affected Product:  See more info
Application Connector TMOS(all modules)

Known Affected Versions:
1.0.0, 1.0.0-420.0, 1.1.0, 1.1.1, 1.1.2, 1.1.3, 1.1.4

Opened: Mar 23, 2017
Severity: 3-Major


When Application Connector is deployed with health monitors, the pool members will appear Red on the standby. When the active traffic-group fails over, it can take several seconds (up to 20) for the pool members to become green.


The Application Connector Service Center is not running on the standby traffic-group, so health checks will not be successful on the standby device until it has started and connected to the Proxies. This can cause the failover to take up to 20 seconds to complete.


This occurs when Application Connector Service Center is deployed in a HA environment. The long failover times can occur with or without health monitors.
