Re: [SR-Users] Crash Kamailio 4.1.3

Hello Daniel, New occurrence happened on Saturday. I got the following information according to your previous email: (gdb) p *msg->pai $2 = {type = HDR_PAI_T, name = { s = 0x7f6a60cd34b8 "P-Asserted-Identity: \"0123456789\"<sip:0123456789@A.B.C.D>\r\nContact: <sip:0123456789@A.B.C.D:5060>\r\nAllow: INVITE, BYE, REGISTER, ACK, OPTIONS, CANCEL, SUBSCRIBE, NOTIFY, INFO, REFER, UPDATE\r\nSupported: path, replaces, timer, tdialog\r\nSession-Expires: 1800\r\nExpires: 300\r\nOrganization: Dialogic\r\nContent-Type: application/sdp\r\nContent-Length: 303\r\n\r\nv=0\r\no=Dialogic_SDP 14338449 0 IN IP4 A.B.C.D\r\ns=Dialogic-SIP\r\nc=IN IP4 A.B.C.D\r\nt=0 0\r\nm=audio 8708 RTP/AVP 8 0 18 101\r\na=rtpmap:0 PCMU/8000\r\na=rtpmap:8 PCMA/8000\r\na=rtpmap:18 G729/8000\r\na=fmtp:18 annexb=yes\r\na=rtpmap:101 telephone-event/8000\r\na=fmtp:101 0-15\r\na=silenceSupp:off - - - -\r\n", len = 19}, body = { s = 0x7f6a60cd34cd "\"0123456789\"<sip:0123456789@A.B.C.D>\r\nContact: <sip:0123456789@A.B.C.D:5060>\r\nAllow: INVITE, BYE, REGISTER, ACK, OPTIONS, CANCEL, SUBSCRIBE, NOTIFY, INFO, REFER, UPDATE\r\nSupported: path, replaces, timer, tdialog\r\nSession-Expires: 1800\r\nExpires: 300\r\nOrganization: Dialogic\r\nContent-Type: application/sdp\r\nContent-Length: 303\r\n\r\nv=0\r\no=Dialogic_SDP 14338449 0 IN IP4 A.B.C.D\r\ns=Dialogic-SIP\r\nc=IN IP4 A.B.C.D\r\nt=0 0\r\nm=audio 8708 RTP/AVP 8 0 18 101\r\na=rtpmap:0 PCMU/8000\r\na=rtpmap:8 PCMA/8000\r\na=rtpmap:18 G729/8000\r\na=fmtp:18 annexb=yes\r\na=rtpmap:101 telephone-event/8000\r\na=fmtp:101 0-15\r\na=silenceSupp:off - - - -\r\n", len = 43}, len = 66, parsed = 0x7f6a6d81da88, next = 0x7f6a60cd3f10} (gdb) p *((p_id_body_t*)msg->pai->parsed) $3 = {id = 0x0, num_ids = 0, next = 0x0} (gdb) I still not patched. Do you schedule to include the patch in 4.1.4? Do you need more information?

The pai seems good, why it cannot be parsed? apparently it was parsed, but then the content got reset. The sip_msg_t for request is accessed via a callback inside acc module when the sip_msg_t for response is handled. So I have to see why it got reset, it shouldn't -- the patch so far was to prevent the crash.
