[rt-users] FastCGI: incomplete headers (0 bytes)

[Erich Weiler]

Greetings all-

So, I recently moved our RT application from  CentOS 4.6 (32 bit) to a 
new machine running CentOS 5.1 (64 bit).  It's RT 3.6.6.  Installed all 
the perl stuff and compiled FastCGI just fine.  I imported the MySQL 
database and everything seems great, users can log in and browse, change 
tickets, etc.

However, we're seeing this odd thing happening now.  Whenever someone 
tried to create a ticket through the RT web interface, it pauses for 2 
minutes, then returns a '500 Internal Server Error'.  I looked at the 
apache error logs and saw this:

[Fri May 16 10:17:46 2008] [error] [client 23.66.56.35] FastCGI: comm 
with server "/usr/local/rt3/bin/mason_handler.fcgi" aborted: idle 
timeout (120 sec), referer: http://barnyard/Ticket/Create.html?Queue=23
[Fri May 16 10:17:46 2008] [error] [client 23.66.56.35] FastCGI: 
incomplete headers (0 bytes) received from server 
"/usr/local/rt3/bin/mason_handler.fcgi", referer: 
http://barnyard/Ticket/Create.html?Queue=23

Weird thing is, if you go back to the RT home page, the new ticket is 
there!!  But it's a pain to have this error, we don't want folks to have 
to wait 2 minutes and get an apache error, then go back to the RT home 
page after that.  It's got to be something with FastCGI but I can't 
figure out what....  Here's the apache configuration include file for 
FastCGI:

FastCgiIpcDir /tmp/
FastCgiServer /usr/local/rt3/bin/mason_handler.fcgi -idle-timeout 120 
-processes 8
FastCgiConfig -restart

I've seen a few other posts with people having similar FastCGI problems 
- can anyone point me in the right direction?

Thanks a million!
