<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif"">I am encountering a problem when the charon is shutting down. Apparently when I am deleting all the rules, the charon instead of shutting down gracefully, is core dumping.
Initially single tunnel is established and traffic is flowing. Then when I try to delete the last rule while traffic is still incoming, the crash occurs. Apparently a phase1 request from the other end while the charon is going down is making it to core dump.
When I took a back trace of the core file, it is showing no stack available. The syslog is as shown below:<o:p></o:p></span></p>
