While restarting unicorn everytime I'm getting this error in capistrano. So how can I fix this ?

Solution

  • The problem is that you have another service listening in port 8080, that's what your log says. If you're using linux you can check which service it is using lsof -i:8080. This will tell you who is using that port. If you can kill the service, just do it, if you can't, just change the port on your config files.
