            I extracted the source opensips-1.11.2-4c08b62_src.tar.gz

            anything after that. The service doesn&#39;t even stop when
            tried to stop cleanly. It just hangs. After a minute or so,
            it shuts down with the following in the logs:<br>

          Should I try with an older stable version instead?? I think

                                                          I get, **
                                                          ERROR: error
                                                          opening read
                                                          fifo
                                                          /tmp/opensips_receiver_24405
                                                          in the
                                                          resulting AVP.
                                                          Whereas when I
                                                          run this
                                                          command
                                                          directly from
                                                          my shell it
                                                          runs fine and
                                                          cancels the
                                                          transaction as
                                                          expected.<br>
                                                          </div>
                                                          Tried to
                                                          google around
                                                          the problem
                                                          and couldn&#39;t
                                                          find much. I
                                                          read about
                                                          some selinux
                                                          thing that
                                                          might block
                                                          opensips from
                                                          executing the
                                                          MI command,
                                                          but I&#39;m pretty
                                                          sure selinux
                                                          is disabled on
                                                          my machine.
                                                          Where else do
                                                          I look for a
                                                          fix such that
                                                          my script is
                                                          able to
                                                          execute this
                                                          !!<br>

                                                          Thanks in
