10.228.22.225/32 1; # o2lb01
10.228.22.226/32 1; # o2lb01-1
10.228.22.227/32 1; # o2lb01-2
}
…
server {
…
error_page 400 /400;
location = ‘/400’ {
if ($lb) { access_log off; }
return 400;
}
…
}

my log-file:

10.228.22.226 - - [27/Jan/2008:22:01:23 +0100] “-” 400 0 “-” “-”

I ran into this a while ago too. I don’t think it works anymore.

Most likely due to your bigip’s “monitor” for that service (port 80),
which at its most generic is a simple TCP/IP-level connect with no HTTP
request behind it.

You must make sure your monitor is a http monitor that does a “GET /”
instead of a simple connect if you don’t want to see HTTP 400.

See the bigip reference for examples.
