PK80196: 404 ERROR RESPONSE SENT BY SIP PROXY DURING SIP CONTAINER FAILOVER USING TCP.

Fixes are available

APAR status

Closed as program error.

Error description

When a Session Initiation Protocol (SIP) container goes into
failover, the SIP proxy returns back 404 error responses to
SIP requests that contain affinity to the failed server. It
should be suspending these until the peer SIP container has
taken over the failed servers sessions.

****************************************************************
* PROBLEM DESCRIPTION: The Session Initiation Protocol (SIP)   *
*                      proxy was not correctly catching all    *
*                      affinity lookup failures.               *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
The SIP proxy was not correctly catching all affinity look-up
failures and suspending the processing of these SIP requests
until the SIP container's peer server has taken over the
sessions of the failed server.

Problem conclusion

The SIP proxy is now catching all affinity look-up failures
and suspending the processing of these SIP requests until
failover has completed.  Once failover has completed the SIP
proxy resumes the processing of the suspended SIP requests
which are then sent to the SIP container that activated the
SIP sessions of the failed SIP container.
