The received security session id related cookie is not valid. The current request will be isolated in a new session. There might be a few reasons causing this behavior: 1) Possible session fixation hacker's attack. 2) The received security session id cookie is already outdated. One possible solution is increasing the value of the 'SecuritySessionIdGracePeriod' servlet_jsp property. For more information read SAP Note 1464914. 3) No security session id cookie is sent (over http) because it is protected via custom configuration of the http service properties 'SecuritySessionIDHTTPSProtection' and 'SystemCookiesHTTPSProtection'. Revise the configuration of the http service properties or adapt the problematic scenario accordingly.#
