<p>Hello,</p>
<p>install gdb and when the kamailio stops responding send here the
file generated by the next command:</p>
<p>kamctl trap</p>
<p>The path to the file is printed when the command is executed.
Note that it can take a bit to generate the file, if you have a
lot of kamailio processes. The file contains the gdb backtrace for
each process, showing what they do at that moment.</p>
<p>For a few of other hints, be sure you don't block the traffic
with the firewall/fail2ban or with pike module in kamailio.cfg.</p>
<p>Cheers,<br>
Daniel<br>

<div dir="ltr">Hi,
<div>
<div>We are using Kamailio with Jitsi client where we observed
sometimes Kamailio stops responding to sip messages. As a
result, my Jitsi client goes offline and never back online.
Also in the Kamailio syslog there are no error logs(debug
enabled) related to this issue. As a temporary workaround,
we had to restart the Kamailio server all the time.</div>
<div>Does anyone observed a similar issue and can suggest any
resolution.</div>
