TMM crashes, and in the core dump file, you can find the following information: 1. cf->flow_type should be FLOW_SERVERSIDE(0x80) 2. sip->pcb should be null (indicating that the client side pcb is released) i.e. the server side flow is accessing the client pcb which is released.
The PCB on the client flow is released and the server flow tries to access it
Fixed a relatively rare coring condition where the SIP filter would access memory that was already freed.
