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.
Thanks.
Regards,
Antón

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
