I’m using passenger and seeing that stdout & stderr are going to nginx’s  
default error log, rather than what’s specified in the server {  
error\_log … } directive. Is this a known bug in nginx or passenger?

```
server {
    listen 8082;
    access_log logs/ruby-access.log main;
    error_log logs/ruby-error.log; ## nothing in here from ruby's

```

$std{out,err}!  
root /Users/paulm/Code/nginx/public;  
location / {  
passenger\_enabled on;  
}  
}

Here’s all the code & config; it’s a trivial Sinatra server:

Phusion Passenger from here: [Install — Phusion Passenger™ (a.k.a. mod\_rails / mod\_rack)](http://www.modrails.com/install.html) (seems  
to install nginx 1.0.10)

(The workaround is to File#reopen in [config.ru](http://config.ru) but I’d like to avoid  
this, if possible.)

Many thanks!

Paul

I can confirm this.

nginx version: nginx/1.0.12  
Phusion Passenger version 3.0.11

In my case, I have error\_log defined at all three levels, as described  
here:

When reopening $stderr in “a” (append) mode, the file is not written to.  
However, when reopening with “w” (write) mode, things work as expected.

Also, since I have the server error log set to debug, reopening $stderr  
also results in other messages being written. For example, info  
messages.
