When accessing Admin UI Access :: Overview :: Active Sessions page, the page status is stuck in 'Receiving configuration data from your device'. TMSH command 'show apm access-info' also hangs.
Some session variables may be lost, which results in the GUI becoming unresponsive. The Access :: Overview :: Active Sessions page in the Admin UI becomes unusable.

Do not toggle between 'Within Cluster' and 'Between Cluster' while traffic is going through the device.
The solution for the reported issue is handled by the fix provided for ID 783817. ID 786173 fixes a null pointer exception that might occur in the specific case of a certain missing session variable, which is relevant only in BIG-IP releases 14.1.0 or later.
