[SR-Users] RPCFIFOPATH / DEFINE_FIFO_NAME settings problem

Hello,
kamailio should attempt to create the /var/run/kamailio folder if the
application is run with enough privileges. However, some operating
systems add more constraints on top of the execution user.
What is your OS distro? Do you have selinux, apparmor or other similar
tools enabled?
Cheers,
Daniel
