Did the CLI work ? If it worked ten you needed to restart the tomcat and the httpd service before a full reboot as the GUI could have ben just stuck:

 

  1. Log in to the command line.
  2. Type the following command to restart the httpd daemon
  3. bigstart restart httpd
  4. Type the following command to restart the tomcat daemon:
  5. bigstart restart tomcat

 

 

 

I have seen such also when the system is overutilized as the GUI is not critical it gets turned off, so that there is more CPU/Memory for the other processes or when someone uses a lot of REST-API scripts and there is no configured tmsh timeout (by default it is not configured and I don't know why F5 networks have not set default timeout) and the scripts don't close correctly the session. I suggest checking the /var/log/kern.log and to monitor you device CPU and memory and SWAP memory to see if they start increasing (memory leakage) .
