[squid-users] PID file /var/run/squid.pid not readable AND Supervising process XXX which is not our child

[Roberto Carna]

Dear, I have Squid/Dansguardian in a Debian 9 server.

My Squid packages is from Debian repo, it is the stable version:

squid                          3.5.23-5+deb9u1

After execute "squid -k parse" everything is OK:

# systemctl status squid

May 09 20:30:35 proxy-nuevo systemd[1]: Starting LSB: Squid HTTP Proxy
version 3.x...

May 09 20:30:35 proxy-nuevo squid[829]: Starting Squid HTTP Proxy: squid.

process 895 started

/var/run/squid.pid not readable (yet?) after start: No such file or
directory
May 09 20:30:36 proxy-nuevo systemd[1]: squid.service: Supervising
process 895 which is not our child. We'll most likely not notice when
it exits.
May 09 20:30:36 proxy-nuevo systemd[1]: Started LSB: Squid HTTP Proxy
version 3.x.

But when I read I notice two curious lines:

systemd[1]: squid.service: PID file /var/run/squid.pid not readable
(yet?) after start: No such file or directory
systemd[1]: squid.service: Supervising process 895 which is not our
child. We'll most likely not notice when it exits.


Is it normal or do I have to solve these? I repeat Squid is running OK...

Thanks
