Re: How to correctly signal postfix to close the session from an TCP Table/Policy Service - Connections are kept open for 1min after service shutdown

[Wietse Venema]

The tcp_table client timeout is not configurable (it also is not
60s).  Closing the socket after each query is wrong.

First, you need to set the SO_REUSEADDR socket option on the LISTEN
socket.

Second, before restarting your server, you need to terminate ALL
tcp table server processes.
