Unable to Web Browse in SBC

My 4600 SBCs have been in production for 2 weeks.  Starting a couple of days ago, I am unable to web browse into the SBC.

The browser session just sits there and eventually times out.

I verified my web-server-config is still enabled.

        state                                   enabled

        inactivity-timeout                      20

        http-state                              enabled

        http-port                               80

        https-state                             disabled

        https-port                              443

        tls-profile

I tried disabling and re-enabling without success.

Short of rebooting the SBC, is there a service that can be restarted or any other diagnosis of the problem?
