Details - There seems to be a potential issue with kamctl.fifo if a script crashes for some reason.

The file /tmp/kamailio_receiver_<pid> might be left again after script finish, and this causes kamctl to fail next time it runs with that pid:
Feb 24 07:04:45 bnsip1ha /usr/sbin/kamailio[16767]: ERROR: mi_fifo [fifo_fnc.c:224]: mi_open_reply_pipe(): open error (/tmp/kamailio_receiver_16613): Permission denied
Feb 24 07:04:45 bnsip1ha /usr/sbin/kamailio[16767]: ERROR: mi_fifo [fifo_fnc.c:488]: mi_fifo_server(): cannot open reply pipe /tmp/kamailio_receiver_16613
Feb 24 07:04:48 bnsip1ha kamailio(kamailio)[16605]: WARNING: Kamailio is not up according to kamctl monitor!


This is not critical at all, but we use "kamctl monitor" from heartbeat for health checking.

Would it be safe to add this to the start of kamctl.fifo, to clean up files that are not deleted?

name=kamailio_receiver_$$
path=$CHROOT_DIR/tmp/$name
if test -p $path; then
        rm $path
fi
