Haproxy 1.7.10 constantly restarting
March 11, 2018 12:30PM
I'm sorry is that question is not suitable. Please give correct channel to contact.

It's started about a month ago. I have separate instances of same version haproxy. One of them restarts every 2 or 3 days.

I have only this in log

Mar 11 06:43:21 .... systemd[1]: Stopping HAProxy Load Balancer...
Mar 11 06:43:21 .... haproxy-systemd-wrapper[10939]: haproxy-systemd-wrapper: SIGTERM -> 10942.
Mar 11 06:43:21 .... haproxy-systemd-wrapper[10939]: haproxy-systemd-wrapper: exit, haproxy RC=0

Mar 11 06:43:21 .... haproxy-systemd-wrapper[19642]: haproxy-systemd-wrapper: executing /usr/sbin/haproxy

I'm not very good in linux. So, what additional info can I provide?

This seems to happen because something is just restarting haproxy. Maybe
logrotate? "rgrep haproxy /etc" may give a clue.

Thank you for answer. Sorry for stupid question. Found it. I forget about
letsencrypt. it restarts when renewing certificates.

Hi Aleksey,

Change it so it does only restart after renewing. I guess, Most of time
it only checks, but doesn't renew.

All the best,
Georg
