Would these orphaned file descriptors indicate thata new socket was created instead of the file descriptors being reused? Eventually, after looking down a bit, you'll see that the /etc/default/haproxy-file is sourced just before the test being performed, thus overwriting the set-variable in the init-script itself... Could you check the exact commandthat is started, to ensure the pids are correct (or present at all) ?Can you also try by hand to first send SIGUSR1 to the old
RHEL has selinux enabled by default I believe, I don't know if that could prevent haproxy from sending a signal to another process. The first vrrp_instance has lb-01 defined as MASTER and lb-02 as BACKUP and the second vrrp_instance has lb-02 defined as MASTER and lb-01 as BACKUP. If any of these operations fail, it will not be able to start.

There are two servers (lb-01 and lb-02). Starting Proxy Webfarm: Cannot Bind Socket How difficult is it to practically detect a forgery in a cryptosystem? The existingHAProxy process contiues to run without picking up the new changes.After the reload initially fails all subsequent 'service haproxy reload'commands also fail.

Instead the Alert (cannot bind socket) is sent to stderr and is logged by consul-template.
