Hi,

it took a while to find the bug, but the patch is trivial:

--- src/core/ngx_cycle.c~ 2009-10-26 17:22:24.000000000 +0100
+++ src/core/ngx_cycle.c 2010-04-11 21:14:43.997932783 +0200
@@ -847,7 +847,7 @@
sin61 = (struct sockaddr_in6 *) sa1;
sin62 = (struct sockaddr_in6 *) sa2;

- if (sin61->sin6_port != sin61->sin6_port) {
+ if (sin61->sin6_port != sin62->sin6_port) {
return NGX_DECLINED;
}

Without the patch reloading will fail, because nginx thinks the two IPv6
addresses are the same regardless of the port.

Regards,
Matthias-Christian
