If you click on the Validation timeout and Idle Timeout columns under Overview/Access Sessions (formerly Managed Sessions), it will result in a general database error.


The access sessions page will be unusable in the current session.


Click on the Column header of the 2 columns (Validation timeout and Idle Timeout) to try and sort them.


If the error occurs, use this to recover: 1. Logout of the BIG-IP session. 2. Clear the browser cache. 3. Login again.

Fix Information

In the session viewer GUI, the Validation Timeout and the Idle timeout are no longer sortable, since they are not relevant to the session data. They are relevant to the sub-session data, which is displayed only if it exists under the corresponding session as leaf nodes.
