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>

fifo is not suitable for heavy traffic - depending on the operating
system, messages in fifo are limited in size. You should consider
using RPC interface over XMLRPC or via sercmd. If you want to stick
to MI control interface, a better option is using datagram
(mi_datagram) via unix socket or inet socket over 127.0.0.1.<br>
<br>

<div bgcolor="#ffffff" text="#000000"> 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>
Cheers,<br>

Removing and creating a new one will not help,

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>
