Hello all,
I've been tearing my hair out trying to get soft-restarts to work reliably, and
have been frustrated for about a week solid. I'm running 1.4.15 on Ubuntu 10.04
amd64, kernel version 2.6.32-32-generic.
The behavior I'm seeing is that -sf restarts will work sporadically from the
command-line.
it prints the output:
[ALERT] 198/213054 (23213) : Starting frontend http-in: cannot bind socket
[ALERT] 198/213054 (23213) : Starting frontend openstack-ssl-in:
cannot bind socket
[ALERT] 198/213054 (23213) : Starting frontend mother-ssl-in: cannot bind socket
[ALERT] 198/213054 (23213) : Starting frontend authoritae-ssl-in:
cannot bind socket
[ALERT] 198/213054 (23213) : Starting frontend encoders-in: cannot bind socket
[ALERT] 198/213054 (23213) : Starting frontend encoders-v2-in: cannot
bind socket
[ALERT] 198/213054 (23213) : Starting frontend redis-in: cannot bind socket
An strace of the restart shows:
17492 socket(PF_INET, SOCK_STREAM, IPPROTO_TCP) = 5
17492 fcntl(5, F_SETFL, O_RDONLY|O_NONBLOCK) = 0
17492 setsockopt(5, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0
17492 setsockopt(5, SOL_SOCKET, 0xf /* SO_??? */, [1], 4) = -1
ENOPROTOOPT (Protocol not available)
17492 bind(5, {sa_family=AF_INET, sin_port=htons(6379),
sin_addr=inet_addr("0.0.0.0")}, 16) = -1 EADDRINUSE (Address already in
use)
17492 close(5) = 0
17492 kill(13512, SIGTTOU) = 0
It does this for every frontend I have defined.
my config is:

I've been going totally crazy trying to get this working. The exact same build
of haproxy on debian lenny seems to restart reliably. I've tried this same
config with 1.4.15 and it exhibits the same behavior. Is there some sysctl I
need to set or something?
Help would be greatly appreciated.
Thanks very much,
Jonathan
