Exception: Could not bind to 0.0.0.0:8080 after trying for 30 seconds

I was deploying Swift using Seagate's Kinetic drives following the deployment guide in github https://github.com/swiftstack/kinetic-swift/wiki/Deployment

I ran the 'netstat -lntp' command to see which process is using the port 8080.

anfield@football:~$ netstat -lntp (Not all processes could be identified, non-owned process info  will not be shown, you would have to be root to see it all.)

The 1 indicates a HDD and 0 indicates SSD


 Now that I know which are SSDs and which are HDDs. Here is how I got detailed information on the HDD and SSD

anfield@football:~$ ps -ef | grep 4303 mayur     4303  1541  1 14:22 ?        00:00:03 /usr/bin/python /usr/local/bin/swift-proxy-server /etc/swift/proxy-server.conf mayur     4308  4303  0 14:22 ?        00:00:00 /usr/bin/python /usr/local/bin/swift-proxy-server /etc/swift/proxy-server.conf mayur     4375  2432  0 14:26 pts/1    00:00:00 grep --color=auto 4303 anfield@football:~$ anfield@football:~$ anfield@football:~$ kill -9 4303 anfield@football:~$ anfield@football:~$ ps -ef | grep 4303 mayur     4378  2432  0 14:26 pts/1    00:00:00 grep --color=auto 4303 anfield@football:~$

The screen shot above shows the Python process that is using port 8080. I killed the process, and then restarted Swift

The Swift process came up fine after that as shown below.
