Hello,
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.
On the other hand, we use fifo pipe quite often to update hastables
(/sht_reload/) and to get hashtable dumps (/sht_dump/). These HTs are
used to implement a CAC mechanism. We also regularly use the
/cr_reload_routes/ command.
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.

Thanks.

Hello,
do you have ctl module loaded? If yes, you can connect with sercmd
and get the pid of the fifo listener:
sercmd> ps
Then connect with gdb:
gdb /path/to/kamailio pidoffifolistener
and get the backtrace.
That should show what the fifo process is doing.
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.
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?
Cheers,
Daniel

Hello,
do you get anything in kamailio log messages when the fifo is
not responding?
No, I didn't find anything regarding the fifo command in the logs.
What version of kamailio do you have?
kamailio-3.0.2, the last time we updated the code was on August
1st, since then it is in production.
Removing and creating a new one will not help, since kamailio
will not reopen, so practically will still use the old file
descriptor.
It makes all the sense.
Cheers,
Daniel
Thank you very much,

Hi all,
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.
kamailio1:~#*kamctl fifo which*
It doesn't respond so I input *Crtl+c* and I get:
/usr/local/lib/kamailio//kamctl/kamctl.fifo: line 89:
/tmp/kamailio_fifo: Interrupted system call
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.
Any help is welcome, what can be happening? Below you can
find info about the pipe and the running kamailio.
Thanks in advance,
Best regards
