Two ruby processes are running for one Rails app

Rails
#1

Hi,

I’m using ruby 1.8.7 with rails app(2.3.11) and deployed the app with
apache server. My app performance is too slow so i configured the app
with new relic and could see the ruby has 2 instances. One is for
ruby(nobody) =201 MB and one more for ruby(root)= 73.9 MB. I killed the
processes but still can see the same. Please help me and say why 2
instances are running for ruby?.

It depends how you are running your app, but passenger for example has a
separate spawner process responsible for starting new application
instances.

PS: your app is using a version of rails which most likely allows remote
code execution.

Please tell me in detail. I couldn’t understand your point.

Short version: assuming you are using passenger, that’s just how it
works.
