Yes. Creating a connection for each query is wasteful, especially
if your process exits after the connection is closed.
You can look at "postconf | grep '= 60'" output and reduce
the time limit, but that will also cost you in performance.
Or you implement Postfix's "fast" restart code.
- Set the SO_REUSEADDR socket option on the listen socket. Code
from Postfix:
int on = 1;
if ((sock = socket(res->ai_family, res->ai_socktype, 0)) < 0)
...error...
if (setsockopt(sock, SOL_SOCKET, SO_REUSEADDR,
(char *) &on, sizeof(on)) < 0)
...error...
if (bind(sock, res->ai_addr, res->ai_addrlen) < 0) {
...error...
- Run your server processes in a separate process group. I use
setsid() for this.
- "kill" your existing server processes. For example "kill -9
-process-group-id". The '-' before the process group ID kills the
process group instead of a process.
- Start a new server process.
