There are several posts on the Russian boards in regards to this issue;  
however, I have not been able to get anything out of them that would  
help. (I tried google translate but it is not the best with technical  
language).

Anyway, I’m getting a lot of these errors in my logs and I have no idea  
what they are. Here are the worker settings in my conf file:

user nginx;  
worker\_processes 5;  
worker\_rlimit\_nofile 8192;

error\_log /var/log/nginx/error.log error;  
pid /var/run/nginx.pid;

events {  
worker\_connections 4096;  
use epoll;  
}

Maxim posted a script perl script on one of the posts that I thought  
might shed some light on my problem:

#!/usr/bin/perl  
use CGI::Fast;  
while (new CGI::Fast) {  
print “Content-type: text/html\n\nOk”;  
warn “”.(“a” x 503).“\n”;  
}

I tried to run this but I’m getting an error when I do:

# /usr/bin/perl fcgi-test.pl

Can’t locate FCGI.pm in @INC (@INC contains:  
/usr/lib/perl5/site\_perl/5.8.8/i386

I also tried to look in the docs for some clues, but I’m out of ideas.

Uhm, time to upgrade? 0.8.35 was released a while ago, and it has  
“fastcgi with large stderr” bug fixed.

You have to install FCGI perl module to use it. But it doesn’t  
actually matter, see above.
