If you want to look in the code… check out libs/esl/src/esl.c for the places that set handle.connected = 0; like all the goto fail cases in esl_connect_timeout. It looks like they all set handle->err to some string with details (i haven’t audited all the cases but you can check for yourself). It doesn’t look like there is a way to access that from the lua currently.. but you could add one easily enough in esl_oop.cpp to just return handle->err and print that out in the lua script. If that is a helpful tool for debugging, feel free to toss a pull request with that change.

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
