Re: [squid-users] Workers reconfigure-question on 3.2.5

Hi

I did run "squid -z" first with "workers 4". The necessary directories
were created successfully.

I did not changed the workers in runtime, so I got no warning
concerning changing the workers.

It makes no differences, if I use "squid -f /etc/squid/squid.conf -k
reconfigure" or "squidclient mgr:reconfigure" instead of "kill -1
$PID". One squid-kid (in my case kid5) always tries to access a
cache-directory after reconfigure. But the directory #5 does not
exist, because I just have 4 workers and for this number of workers, I
certainly have a cache_dir.

How does others reconfigure their squid with workers running?
