<p></p> <h3 dir="auto">Description</h3> <p dir="auto">Hi, I am a junior with Kamailio, if I show you where I am wrong, I will. Often during a call between two sip clients (located on the same subnet with pcscf) Kamailio P-CSCF crashes with a core dump. But sometimes the call goes through normally, I can’t see why this is happening.</p> <h3 dir="auto">Troubleshooting</h3> <h4 dir="auto">Reproduction</h4> <p dir="auto">It is reproduced often, the error is most likely somewhere with me.</p> <h4 dir="auto">Debugging Data</h4> <pre><code>GNU gdb (Debian 10.1-1.7) 10.1.90.20210103-git Copyright (C) 2021 Free Software Foundation, Inc.
