Bench start in production is not working

I use vultr service using new server and I tried steps provided here

Previously I run bench start it complained port 11000, 12000, 13000 already in use. So I changed them into 11011, 12011, 13011. All redis services are now started, but now it complained event.js is not working because some address already in use.

Please advice.

Here is my log

Thanks in advance!

Update: I use ubuntu 14.04 32bit

Update #2: Changed common_site_config.json
from 11000, 12000, 13000 to 11011, 12011, 13011
also changed 9000 and 8000 ports to 9011 and 8011
different errors are arised…

I get port 11000, 12000, 13000 already in use error when some times I do bench start multiple times in a row. you can kill the process that are using these ports manually or just simply restart the server

Use
bench restart
When in production mode

Thanks!
