I found that this UCCX version 9.02 error also applies to UCCX version 11.0.1.10000-75.

admin:set weba

Continuing with this operation will set the session-timeout for web sessions to 540 minutes after the 'Cisco Tomcat' service has been restarted or after the server has been rebooted.
Continue (y/n)?y
Internal error: Tomcat session-timeout values were not updated.
