Hi, We are facing a crash in a PJSIP while receiving an incoming call - the point at which it is crashing is when an ACK is received. Here is what we are doing: - When an INVITE message is received, a UAS dialog is created - Send 180 Ringing, 200 OK on the same dialog - An ACK is received from the server The ACK is destroying the transaction. After this, a timer expires and tries destroy the already destroyed transaction and it crashes there. You can see the same from the following log snippet: 16:25:49.016 sip_endpoint.c Processing incoming message: Request msg INVITE/cseq=15725 (rdata01221854) 16:25:49.672 tsx0189A7CC Transaction created for Request msg INVITE/cseq=15725 (rdata01221854) 16:25:49.672 tsx0189A7CC Incoming Request msg INVITE/cseq=15725 (rdata01221854) in state Null 16:25:49.672 tsx0189A7CC State changed from Null to Trying, event=RX_MSG 16:25:49.672 dlg01279A1C Transaction tsx0189A7CC state changed to Trying 16:25:49.672 dlg01279A1C UAS dialog created 16:25:49.672 dlg01279A1C Module mod-invite added as dialog usage, data=0127A020 16:25:49.672 dlg01279A1C Session count inc to 2 by mod-invite 16:25:49.672 inv01279A1C UAS invite session created for dialog dlg01279A1C 16:25:49.672 endpoint Response msg 180/INVITE/cseq=15725 (tdta0126B198) created 16:25:49.672 dlg01279A1C Initial answer Response msg 180/INVITE/cseq=15725 (tdta0126B198) 16:25:49.672 inv01279A1C Sending Response msg 180/INVITE/cseq=15725 (tdta0126B198) 16:25:49.672 dlg01279A1C Sending Response msg 180/INVITE/cseq=15725 (tdta0126B198) 16:25:49.672 tsx0189A7CC Sending Response msg 180/INVITE/cseq=15725 (tdta0126B198) in state Trying 16:25:49.672 sip_resolve.c Target '10.2.1.164:5060' type=UDP resolved to '10.2.1.164:5060' type=UDP 16:25:49.672 tsx0189A7CC State changed from Trying to Proceeding, event=TX_MSG 16:25:49.672 dlg01279A1C Transaction tsx0189A7CC state changed to Proceeding 16:25:49.672 inv01279A1C SDP negotiation done, status=220049 16:25:49.672 inv01279A1C Sending Response msg 200/INVITE/cseq=15725 (tdta0126B198) 16:25:49.672 dlg01279A1C Sending Response msg 200/INVITE/cseq=15725 (tdta0126B198) 16:25:49.672 tsx0189A7CC Sending Response msg 200/INVITE/cseq=15725 (tdta0126B198) in state Proceeding 16:25:49.672 tsx0189A7CC State changed from Proceeding to Completed, event=TX_MSG 16:25:49.672 dlg01279A1C Transaction tsx0189A7CC state changed to Completed 16:25:49.672 sip_endpoint.c Processing incoming message: Request msg INVITE/cseq=15725 (rdata01221854) 16:25:49.672 tsx0189A7CC Incoming Request msg INVITE/cseq=15725 (rdata01221854) in state Completed 16:25:49.672 tsx0189A7CC Retransmiting Response msg 200/INVITE/cseq=15725 (tdta0126B198), count=0, restart?=0 16:25:49.781 sip_endpoint.c Processing incoming message: Request msg ACK/cseq=15725 (rdata01221854) 16:25:49.781 dlg01279A1C Received Request msg ACK/cseq=15725 (rdata01221854) 16:25:49.781 tsx0189A7CC Request to terminate transaction 16:25:49.781 tsx0189A7CC State changed from Completed to Terminated, event=USER 16:25:49.781 dlg01279A1C Transaction tsx0189A7CC state changed to Terminated 16:25:49.781 tdta0126B198 Destroying txdata Response msg 200/INVITE/cseq=15725 (tdta0126B198) 16:25:49.875 tsx0189A7CC Timeout timer event 16:25:49.875 tsx0189A7CC State changed from Terminated to Destroyed, event=TIMER Thanks, Manoj -------------- next part -------------- An HTML attachment was scrubbed...
