Hello!
I just wanted to share something interesting that just happened on my squid
server.
I had rebooted my squid server and walked away for a bit. After returning, I noticed that squid
wasn't working. I found out because I was not able to browse using the proxy. After looking through
the cache.log, it seemed like squid should have been running. The cache.log file said
"2012/02/08 00:18:58| Squid is already running! Process ID 1288". I did a "ps -ef |
grep squid" and was not able to find anything. I also did a ps -ef | grep 1288 and no process
with the number 1288 showed. Next I did a netstat -ntlp and did not see the server listening on
port 3128. I wasn't sure where to look to see where this so called process ID 1288 was running.
After doing a bit of searching online, I ran into the tool called htop. I ran
htop and I was able to see the process 1288. It said that it was mysql. I went
ahead and killed that process and attempted to start squid again and it started
up fine. Unfortunately I didn't save the info that htop provided to me. I found
it kind of weird that this happened.
It is based on the contents of the PID file. Sometimes after a crash an
old value is left there.
It seems mysql was assigned the same ID between when that Squid process
crashed and when you restarted.
