    <p>Hello,</p>
    <p>can you remove the KSR.x.exit() and test again? It will be the
      same effect from sip routing point of view, just to see what is
      the result.</p>
    <p>Because Lua 'exit' cannot be used, KSR.x.exit() is a workaround
      relying on error/exception handling with string comparison that I
      did.</p>
    <p>However, overall KSR.x.exit() alone has an insignificant effect
      on a production configuration, based on the tests I did for
      kamailio 5.2, you can look for more at:</p>

        <div>Hi Daniel,</div>
        <div><br>
        </div>
        <div>For lua example, it's just an error when writing my
          email... in my config file I have KSR.x.exit();</div>
        <div>I have not tested a more complex config, but I'm curious
          about kemi framework and how it works. So before anything else
          I made a simple test to know the cpu overhead.</div>
        <div>For this test, I noticed that the Recv-Q of kamailio
          remains high with kemi/lua, and with the native one remains to
          0, with children=1 of course.</div>
        <div>Next step, is to use a more complex config file.</div>

              <p>Hello,</p>
              <p>is it really just 'exit' in the ksr_core_received()?
                Because that should shut down kamailio.</p>
              <p>Anyhow, practically with the examples here, you test
                the difference between looking up a function and doing
                exit in native kamailio.cfg and lua script, which is
                really marginal comparing with the rest of configuration
                file in a usual production deployment. Have you tested
                with a more complex set of actions/functions?</p>
