When performing a policy-sync the GUI disconnects from the BIG-IP system, and the Administrator will not be able to access the platform.
Once disconnected the GUI does not always connect to the server, which means you must connect via ssh and then run the command: bigstart restart tomcat. This restarts the GUI. Once back up, the GUI should be usable.
This most often occurs when a large number of devices are within the device group being synced to. The exact number of devices that will cause this issue depends upon the specifications of the platform you are using (less powerful machines might be affected while syncing to smaller numbers), and the size of the policy being synced. If the policy is large or contains hosted content files, you are more likely to experience this issue.
Run the command: bigstart restart tomcat. This restarts the GUI. Once back up, the GUI should be usable.
