Hi all,<br><br>I&#39;m having trouble trying to execute fifo commands with &quot;kamctl fifo &lt;command&gt;&quot;. Just after restarting Kamailio it works fine, however, sometimes after some days running it doesn&#39;t respond. <br>

<br>kamailio1:~#<b> kamctl fifo which</b><br><br>It doesn&#39;t respond so I input <b>Crtl+c</b> and I get:<br>/usr/local/lib/kamailio//kamctl/kamctl.fifo: line 89: /tmp/kamailio_fifo: Interrupted system call<br><br>If I delete and create the fifo file again (with &quot;rm /tmp/kamailio_fifo&quot; and &quot;mkfifo /tmp/kamailio_fifo&quot; and &quot;chmod 660 /tmp/kamailio_fifo&quot;) it keeps not responding.<br>

<br>Any help is welcome, what can be happening? Below you can find info about the pipe and the running kamailio.<br><br>Thanks in advance,<br>
Best regards<br>
<br>
