Hi

I'm trying to use a simple lua event consumer like this:

connnn = freeswitch.EventConsumer('CHANNEL_HANGUP');
freeswitch.consoleLog("NOTICE", "waiting for event \n");
e = con:pop(1,500)
freeswitch.consoleLog("NOTICE", "ssssssssssssssstop waiting for event \n");
freeswitch.consoleLog("NOTICE", e:serialize().."\n");

but lines after consumer creation are never executed! if I comment the first line, next lines are executed successfully, scripts blocks at the first line

my lua xml config is like this:

<configuration name="lua.conf" description="LUA Configuration">
  <settings>   
    <param name="module-directory" value="/usr/local/lib/lua/5.2/?.so"/>    
    <param name="startup-script" value="jobs/rk-token-update.lua"/>   
    <hook event="DETECTED_TONE"  script="on_tone.lua"/>
     <hook event="CHANNEL_BRIDGE"  script="onbridge.lua"/>
     hook event="CHANNEL_UNBRIDGE"  script="onbridge.lua"/>
  </settings>
</configuration>

fs is an old box with version 1.6
