Symptoms

Virtual servers with an SCTP profile and a SIP message-routing profile may crash the TMM.

Impact

TMM crashes and fails over, disrupting traffic processing. Traffic disrupted while TMM restarts.

Conditions

This flaw affects virtual servers that pass SCTP traffic, where the SIP message-routing profile has the record-route option enabled.

Workaround

Remove the record-route option, or change the traffic to use TCP or UDP instead of SCTP.

Fix Information
