RE: [squid-users] Squid not running, PID exists

Same thing. I start squid:

/usr/local/squid/sbin/squid

And then I kill it:

/usr/local/squid/sbin/squid -k kill

PID file still exists.

Hi,

Change in squid.conf the line pid_filename to:

pid_filename /usr/local/squid/var/squid.pid

And start the squid.

Interesting. When I start it in debug mode (-NCd1) the squid.pid appears.
When I stop squid in debug mode the squid.pid goes away. Why is this not
happening when not running debug mode?

The /usr/local/squid directory and everything below is owned to squid user,
which is the effective user.

1 - If you start squid in debug mode, see the result, paste output here
please.

# squid -d

2 - Maybe the directory is not owner squid, verify permissions.

Assunto: [squid-users] Squid not running, PID exists

When squid is running, /usr/local/squid/var/logs/squid.pid exists
If I kill squid, the pid file still exists.
If I restart squid it just overwrites the squid.pid with the new PID

Anyway I can tell squid when its not running to ditch the PID file (without
relying on scripts and cron jobs to test for this?)
