I think I can reproduce this and a similar bug that causes a SEGFAULT (on load or config check) when 'disabled' appears in a backend using the config shown below.
defaults timeout client 5s timeout server 5s frontend main :8888 default_backend one backend one backend two disabled A git bisect shows it breaking with commit 91b00c2194b728ccd61133cca83f03de3650b674 is the first bad commit commit 91b00c2194b728ccd61133cca83f03de3650b674 Author: Willy Tarreau <[email protected]> Date: Tue Sep 16 13:41:21 2014 +0200 MEDIUM: config: compute the exact bind-process before listener's maxaccept This is a continuation of previous patch, the listener's maxaccept is divided by the number of processes, so it's best if we can swap the two blocks so that the number of processes is already known when computing the maxaccept value.
