Hello,<br><br>I've already got the fifo listener PID. Kamailio had to be restarted and now it's working fine. When it gets unresponsive again I'll check it with gdb. I'll keep you informed. <br> <br>On the other hand, we use fifo pipe quite often to update hastables (<i>sht_reload</i>) and to get hashtable dumps (<i>sht_dump</i>). These HTs are used to implement a CAC mechanism. We also regularly use the <i>cr_reload_routes</i> command.<br>
<br>Thanks.<br><br>Regards,<br>Antón<br><br><div class="gmail_quote">2011/1/18 Daniel-Constantin Mierla <span dir="ltr"><<a href="mailto:miconda@gmail.com" target="_blank">miconda@gmail.com</a>></span><br><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">

Hello,<br>
<br>
do you have ctl module loaded? If yes, you can connect with sercmd
and get the pid of the fifo listener:<br>
<br>
sercmd> ps<br>
<br>
Then connect with gdb:<br>
<br>
gdb /path/to/kamailio pidoffifolistener<br>
<br>
and get the backtrace.<br>
<br>
That should show what the fifo process is doing.<br>
<br>
Also, you can get the pid of fifo process at startup, with kamctl
ps, store it for the time when it blocks in order to use it with
gdb.<br>
<br>
I haven't encountered this issue, do you have lot of communication
over fifo file? How many commands and how often are sent through
fifo file?<br>
<br>

<div>kamailio-3.0.2, the last time we updated the code was on
August 1st, since then it is in production. <br>

Removing and creating a new one will not help, since
kamailio will not reopen, so practically will still use the
old file descriptor.<br>

<div>Hi all,<br>
<br>
I'm having trouble trying to execute fifo commands
with "kamctl fifo <command>". Just after
restarting Kamailio it works fine, however, sometimes
after some days running it doesn't respond. <br>
<br>
kamailio1:~#<b> kamctl fifo which</b><br>
<br>
It doesn'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 "rm
/tmp/kamailio_fifo" and "mkfifo /tmp/kamailio_fifo"
and "chmod 660 /tmp/kamailio_fifo") 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>
Antón <br>
