[Freeswitch-users] Get disconnected message

Hi all, I've a simple lua esl script to handle fs events outside the main program, were: while(con:connected() == 1) do -- get and act on con:events -- break the loop on event SERVER_DISCONNECTED or SHUTDOWN done It works quite well, but at some points the loop just breaks without the receiving any control event (disconnected or shutdown) and i can't figure out why it breaks. I got it running for 5 h... Is it possible to get the cause why con:connected() is returning 0? or some log i could enable? The scripts is running on debian 8.6 and Lua 5.2.3. Thanks, António
