CSS 11051: Sorry Server receives request although the normal server is up

Question

Hello,
my customer has configured a sorry for his server. If the normal server is down the Sorry Server receives the requests. That works fine. But if the normal server comes back the Sorry Server still receives some requests( 2 hours and more). Has anybody an idea what might be the reason for that ?

According to: http://www.cisco.com/warp/public/117/css_sorry_server.html “After the CSS 11000 directs requests to a primary sorry server, the switch will continue to use the primary sorry server even when the original server becomes functional. To force the connection back to the original server, you must suspend the primary sorry server or wait until the connection is dropped or times out. When a new session is initiated by the CSS 11000, the connection should go back to the original server.”
