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.

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.
