# Introduction

This module closes s2s connections when

[mod_smacks][doc:modules:mod_smacks] reports that a connection has not

received a timely acknowledgement as requested, indicating that the

connection is broken or the remote server is not responding.

With the connection closed, the next stanza to be directed to that

server will trigger Prosody to establish a new connection, instead of

queueing it on the potentially broken connection.

This should prevent messages from being stuck in a queue for a

potentially long time before being bounced back to the sender as

delivery failure reports.

Normally the amount of time it takes for a broken connection to time out

is determined by TCP.

If this is deemed sensible behavior then it will likely be merged into

Prosody itself somewhere.
