Hello,

do you get anything in kamailio log messages when the fifo is not responding?

What version of kamailio do you have?

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

Cheers,
Daniel

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

Antón
