I have noticed that sometimes HAProxy stops writing the HTTP access log entries to the logger after an OS reboot and reports this error:
sendmsg()/writev() failed in logger #1: Permission denied (errno=13)
It was working as expected before the reboot, this is running Ubuntu 24.04 and HAproxy 2.8 from the Ubuntu repos.
To solve this I run:
sudo systemctl restart systemd-journald
sudo systemctl restart haproxy
And HAProxy starts writing again the http logs.
The HAProxy service configuration file looks like this:
[Unit]
Description=HAProxy Load Balancer
Documentation=man:haproxy(1)
Documentation=file:/usr/share/doc/haproxy/configuration.txt.gz
After=network-online.target rsyslog.service
Wants=network-online.target
There is no mention of systemd-journald, CoPilot suggests that a Requires entry should be added via an override to add a dependency on journald, the cause of the problem may be HAProxy starting before journald has set up its socket.
The proposed override:
[Unit]
After=systemd-journald.service
Requires=systemd-journald.service
I would like to know your opinions on this.
Thank you very much.
