Backend Servers wont update (nginx-stream-upsync-module)

[austinbenincasa]

Description

If one is using the nginx-stream-upsync-module to dynamically update a upstream's backend servers the nginx-module-sts will never recognize the new backend to pull stats from. Stats are properly calculated for the initially defined backend server in servers.conf however any update to the file from the upsync module will not be registered without a nginx restart.
