Just to be sure, the sample application I provided also crash when I use 
vortex_connection_shutdown on the listener and not 
vortex_connection_close. Did you manage to reproduce it ?

What I'm trying to achieve is to inform the vortex engine that it must 
stop accept new connections on the specified listener (because I want to 
actually stop the module)

This raises another issue, how do I actually close connections opened by 
one specified listener ? I assumed they were closed when killing the 
listener. vortex_exit() isn't a proper solution as it's global and I do 
have other parts of my application using vortex for different purposes

Thanks,
