Dear All,I have FS configured/compiled with "devel-bootstrap.sh" for better debugging. Is it possible to extract the parsed SIP message from a core dump (or as much SIP as possible.) traversing the back trace, I was able to see host, port, destination number which seems to be fine but I have a feeling there might be some structures with deep SIP info. I'm having random core dumps and I would like to get ideas at the call patterns that causes this crash. I will for sure report all details on this particular crash to JIRA for better tracking. In the mean time, any guidance is appreciated.
