Without looking at it in detail, the number 1018 is so close the the typical
1024 fd limit that most likely, you never close connections. On GNU/Linux,
you can look at /proc/pid/fd when it hangs to see if that is the case, or you
can increase the ulimit to see if that incraeses the number of requests it
handles.

If that is the case, your script probably doesn't hang, but work more or
less normally - it just cannot accept more connections.
