Dear All,
I am a newbie here, I have a Redhat Linux server ES 3 running Squid, serving as a proxy.

This morning internet access went down, after looking around and googling a bit got started with service status commands etc.

When I do a service squid status I get:

squid dead but pid file exists
squid: ERROR: Could not send signal 0 to process 4220: (3) No such process

Ok, so I found the pid file under /var/run/squid.pid and did rm /var/run/squid.pid, and also run command for clear the squid cache rm -rf /var/spool/squid/* and all object are gone, and i restart the squid service but it's still show the error and squid still not work.

Can u guys help me out here ?

Thanks,

Boly

Hopefully there's more info in your squid logs. Can you have a look in your access, cache and store logs and post the entries from the shutdown and startups commands that you ran? Their location is specified in squid.conf in the settings access_log, cache_log and cache_store_log.

Thanks for reply,
sorry, i already remove all the squid and all log are gone, so i cannot post this log file. but normally if this error message happend, how can we fix it without reinstall sqid?

Fixing it would depend on what the error was... I don't know why it wouldn't re-start the first time, but I'm guessing that for your second problem after you deleted the cache directories that you needed to run squid -z to re-build the cache directories.
