The issue coule be related to tomcat service. There were numerous Tomcat related bugs on CUCM 7.1. Please restart the Cisco Tomcat service on the Sub to begin with, check the output of "utils diagnose test" for any tomcat related issues. Also, upgrade to latest version of 7.1.5 if you haven't done already.
