SYMPTOMS
In Microsoft Connected Services Framework (CSF) Server 2.5, the Session component cannot route a message between two participants when the following conditions are true:
 * The session is being restored from the session database after the session has been swapped out of memory.
 * At least one session participant has an expired Web Service Description Language (WSDL) file.
 * At least one session participant is no longer available or does not return a WSDL response.



CAUSE
This problem occurs because the Session component tries to query all session participants for an updated WSDL file. This query includes participants that are not required for the current message routing request. If any participant does not respond, the Session component will not route the message. Therefore, a participant that is not required for the current message routing request can prevent the message from being routed.

MORE INFORMATION
For example, if you use the CSF 2.5 version of the SERT tool to create a session, and then you close the SERT tool before the Session component sends a message routing request, the request fails when the following conditions are true:
 * The session is no longer in memory.
 * The WSDL has expired.

The SERT tool adds itself as a participant when the session is first created. However, the SERT tool does not automatically remove itself from the session’s participant list when you close the tool.

To resolve this problem, the hotfix modifies the behavior of the Session component. The Session component will honor the message routing request regardless of whether a participant is missing or has failed, as long as the missing or failed participant does not play a role in the specific request.
