On my Linux server I ran:

sudo thin start -p 80 -d

Now I'd like to restart the sever. The trouble is, I can't seem to get the old process to kill it. I tried:

netstat -anp

But what I see on port 80 is this:

Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      -         

So, it didn't give me a PID to kill...

I tried pgrep -l thin but that gave me nothing. Meanwhile pgrep -l ruby gives me like 6 processes running. I don't really understand why multiple ruby threads would be running, or which one I need to kill...

How do I kill / restart the thin daemon?
