I trying to debug Errorwith mi_fifo an d I found out that file kamailio_fifo is missing from the directory /tmp, also I not found it in my Debian by locate command. I have correctly following lines in my conf files:

in kamailio.cfg:

loadmodule "mi_fifo.so"

modparam("mi_fifo", "fifo_name", "/tmp/kamailio_fifo")

in kamctlrc:

OSER_FIFO="/tmp/kamailio_fifo"

So, I dont know, it maybe my mysql crashed?

Thank you for you help!
