Hello,

have you look at the PID, is it done for the same process? Can you send
some sample syslog messages?

Also what is the version of your lua?

Cheers,
Daniel

      <div dir="ltr">Hi<br>
        For now as I see:  every request that calls lua script reevables
        my global lua variables <br>
        <br>
        For example
        <div><br>
          I trying to connect to DB via luasql driver and checking if
          connection already existis to avoid new connection<br>
          <br>
          I have function init() that calls in ksr_request_route()<br>
          <br>
          Inside i have ome check: <br>
          <br>
          if not CON then <br>
          <div><br>
          </div>
          <div>    CON =
assert(MYSQL:connect(DBdata.dbname,DBdata.username,DBdata.password,DBdata.host,DBdata.port))</div>
  <div><br>
          </div>
          <div><span style="white-space:pre">		</span>if not CON then</div>
          <div><span style="white-space:pre">			</span>KSR.log("info","|init|log|
            DB NOT connected\n")</div>
          <div><span \
style="white-space:pre">			</span>KSR.sl.sl_send_reply(503,"Internal  server error") \
</div>  <div><span style="white-space:pre">			</span>KSR.x.exit()</div>
          <div><span style="white-space:pre">		</span>else </div>
          <div><span style="white-space:pre">			</span>KSR.log("info","|init|log|
            DB connected\n")</div>
          <div><span style="white-space:pre">		</span>end</div>
          <div>end<br>
            <br>
            So in this case if CON was already created it should not try
            to connect<br>
            <br>
            But for now it tries for every request. So means kemi not
            stores global lua variables between sessions (in one
            kamailio process)<br>
            <br>
            Also as I know INIT routes initiates before lua machine will
            be started so it not allowed to init some lua global
            variables in the init routes<br>
            <br>
            So my question is there is a way to keep global vars per
            kamailio process instead per kamailio request?<br>
            <br>
            <br>
          </div>
        </div>
      </div>
