Hello,

This is the result, always for frame 5 :

(gdb) p *t->uas.request->pai
$1 = {type = HDR_PAI_T, name = {
    s = 0x7f6a60cd34b8 "P-Asserted-Identity: \"0987654321\"<sip:0987654321@A.B.C.D>\r\nContact: <sip:0987654321@A.B.C.D:5060>\r\nAllow: INVITE, BYE, REGISTER, ACK, OPTIONS, CANCEL, SUBSCRIBE, NOTIFY, INFO, REFER, UPD"..., len = 19}, body = {
    s = 0x7f6a60cd34cd "\"0987654321\"<sip:0987654321@A.B.C.D>\r\nContact: <sip:0987654321@A.B.C.D:5060>\r\nAllow: INVITE, BYE, REGISTER, ACK, OPTIONS, CANCEL, SUBSCRIBE, NOTIFY, INFO, REFER, UPDATE\r\nSupported: path,"..., len = 43}, len = 66, parsed = 0x7f6a6d81da88, next = 0x7f6a60cd3f10}
 
(gdb) p *((p_id_body_t*)(t->uas.request->pai->parsed))
$2 = {id = 0x0, num_ids = 0, next = 0x0}

Did you find one thing in common between the 2 occurrences? Do you have any ideas about what is the cause of this pai reset?

Regards,

Igor
