Error in post2/implementation.cpp: 1156 with passenger 4.0.2 and Ruby 2.0.0

[draxxxeus]

had deployed a Sinatra App using passenger gem version 3.0.19 on Ruby 1.9.2-p290 and it was working fine. When I upgraded my Ruby to 2.0.0 and passenger to 4.0.2, I am getting this line in /var/log/httpd/error_log

[ 2013-05-09 10:18:40.7277 6116/41715940 Pool2/Implementation.cpp:1156 ]: [App 6157 stderr] 172.16.24.58 - - [09/May/2013 10:18:40] "GET / " 1146 - 0.0018

This is not a problem, your app is just printing text to stderr and Phusion Passenger forwards it to the Apache log file.

Then you need to look in your Sinatra logs, or the logs of whatever web framework you're using.

[Sudeep Agarwal]

Well, I am sure if I am correct here but when I run the same app on
Thin or Unicorn I don't get any error and stuff works fine. This is
the configuration i am using in Sinatra:

set :show_exceptions, true
set :raise_errors, true
set :dump_errors, true
set :logging, true

[Hongli Lai]

Have you tried Phusion Passenger Standalone? Run 'passenger start' in your app directory.

[Sudeep Agarwal]

This worked. I did passenger-install-apache2-module again and
restarted httpd. And voila! everything is working.

I still don't know what fixed it.

Thanks a lot for your time and help..

I have a related issue here: I am getting these log message headers in every line and looks like this started from passenger 4.0.5. I am using rails 3.2 app with nginx web server. Can someone point into right direction to not show this header part or customize it.

Hi Sulabh Jain,

Sorry for the late reaction. I can't really follow what the problem is. Could you paste the complete log of the error occurring, and some context to what you are trying to do? Also are you using the latest version of Passenger?

Kind regards,
Tinco
