<h3 dir="auto">Description</h3>
<p dir="auto">We have a rare crash in kamailio v5.3 running on Debian Buster in production environment. The crash (segmentation fault) happens while app_json module is writing accounting data to syslog upon receiving ACK for successful INVITE transaction over IPv6 UDP socket.</p>
<h3 dir="auto">Troubleshooting</h3>
<p dir="auto">We checked the server health and service load at the time of crash, everything looks normal. We inspected the core dump generated by kamailio, and it seems that there is some sort of race condition causing the crash, the ACK completes the INVITE transaction, so kamailio was fetching the transaction data from memory to write accounting record to syslog, however, that data is corrupted or deleted by some other kamailio process. We do not see anything unusual in kamailio log related to crash. Perhaps it is related to this older but <a href="https://github.com/kamailio/kamailio/issues/2998" data-hovercard-type="issue" data-hovercard-url="/kamailio/kamailio/issues/2998/hovercard">unresolved crash report</a>.</p>
