--- Comment #16 from Alexander Zaytsev <thebestzorro at yandex.ru> ---
Hi, I have this problem in following case:
- sshd config file contains a line: 
  ListenAddress 0.0.0.0
- after that this record was changed (this host has 3 DNS records): 
  ListenAddress 192.168.0.101
  ListenAddress 192.168.0.102
  ListenAddress 192.168.0.103
- a restart of sshd prints in syslog:
  error: Bind to port 22 on 192.168.0.101 failed: Address already in
use.
  error: Bind to port 22 on 192.168.0.102 failed: Address already in
use.
  error: Bind to port 22 on 192.168.0.103 failed: Address already in
use.
- method packet_set_connection() is not called, the code of
server_listen() detects true condition "if (!num_listen_socks)", but
method packet_connection_is_on_socket() from packet.c tries to use
incorrect operation: if (active_state->connection_in ==
active_state->connection_out)

I don't know why ports are not available for bind, restart script use
"start" and "stop" calls with a delay 2 seconds. It is a quite rare
case, I have a reproduction ~5% only on OS starting. The proposed patch
resolves this problem.
