After rebooting the device you are unable to access the GUI. When checking the LTM logs in the SSH/console, it repeatedly prompts an error: tmm crash. Failed to reset strict operations; disconnecting from mcpd.


Mcpd fails to fully load and the device fails to come up fully, and it cannot pass traffic. An internal timer might cause the installation to be aborted and all daemons to be restarted through bigstart restart. Traffic is disrupted while tmm restarts.


-- APM provisioned. -- Previous EPSEC packages that are still residing on the system from earlier BIG-IP versions are installed upon boot.


You can recover by restarting the services. Traffic will be disrupted while tmm restarts: 1. Stop the overdog daemon first by issuing the command: systemctl stop overdog. 2. Restart all services by issuing the command: bigstart restart. 3. Wait for 10 to 20 mins until EPSEC packages are successfully installed and mcpd successfully starts. 4. Start the overdog daemon after the system is online systemctl start overdog.
