Description Jeremy Harris 2019-12-02 16:04:16 UTC

This is an effective clone of bz 1444709; the same syptom being seen for 8.1
as that bug had for 7.3 :-

Comment 1 Ryan O'Hara 2019-12-02 16:32:00 UTC

Not sure this is the same thing as bz 1444709. That bug was fixed by using KillMode=mixed in the systemd service file. RHEL8 definitely uses KillMode=mixed.

Comment 2 Ryan O'Hara 2019-12-03 18:24:33 UTC

Found something interesting in the upstream systemd service file:

----

[Unit]
Description=HAProxy Load Balancer
After=network.target

[Service]
Environment="CONFIG=/etc/haproxy/haproxy.cfg" "PIDFILE=/run/haproxy.pid"
ExecStartPre=@SBINDIR@/haproxy -f $CONFIG -c -q
ExecStart=@SBINDIR@/haproxy -Ws -f $CONFIG -p $PIDFILE
ExecReload=@SBINDIR@/haproxy -f $CONFIG -c -q
ExecReload=/bin/kill -USR2 $MAINPID
KillMode=mixed
Restart=always
SuccessExitStatus=143
Type=notify

----

Note the "SuccessExitStatus=143" line. That is exactly the exit status shown above. I added this line to the service file and reloaded. Seems to fix it.
