Wow.  Thanks a lot for taking time to work on this.  I had tried setting 
the ipc dir last night, and I even read the manual :) but got error 
messages during apache startup, so I took it out.  The weird thing is, 
unless I chmod the logs/fastcgi directory to 777, the server can't 
access it, even though the server is supposed to be running as apache 
and the directory is owned by apache.  The error message it was giving 
me was:

Syntax error on line 223 of /etc/httpd/conf/httpd.conf:
FastCgiIpcDir /etc/httpd/logs/fastcgi: access for server (uid -1, gid 
-1) failed: write not allowed

When I recursively chmod it to 777, I stop getting the error message on 
Apache startup, but I wanted a less kludgy solution.  I found that the 
problem was because httpd.conf was setting the apache user later on in 
my conf file.  After I moved the user and group settings to the top of 
the conf file, the error on startup went away without having to 777 the 
fastcgi log dir.

However,  I was still getting the 500 error, even after following all of 
your suggestions.  It appears that the error is related somehow to this 
directory, because my error log says:

[Tue Sep 30 16:18:40 2003] [crit] (13)Permission denied: FastCGI: can't 
create (dynamic) server "/var/www/cgi-bin/test.fcgi": bind() failed 
[/etc/httpd/logs/fastcgi/dynamic/35830e69d0669b031643022d74f2d729]
[Tue Sep 30 16:18:44 2003] [alert] [client 127.0.0.1] (13)Permission 
denied: FastCGI: failed
to connect to (dynamic) server "/var/www/cgi-bin/test.fcgi": something 
is seriously wrong, any chance the socket/named_pipe directory was 
removed?, see the FastCgiIpcDir directive

As if it is trying to create some temporary file in this directory and 
is failing.  The problem is that even when it is 777 it still seems to 
fail.  Adding the ENV statement in the fcgi script didn't seem to do 
anything.

So I went out to the web to look for this particular error and I found a 
posting about someone who had the same problem with red hat 8 here: 
http://www.fastcgi.com/archives/fastcgi-developers/2002-December/002470.html

He said that since the server root is in /etc/httpd and that 
/etc/httpd/logs is really a symlink to /var/log/httpd, fastcgi is having 
permission problems.  The solution is to get rid of the /etc/httpd/logs 
symlink and make it a real directory instead, copying all the old log 
files from /var/log/httpd into the new directory.  Then just 
leave FastCgiIpcDir the same or even get rid of it and it will work 
fine.  I guess fastcgi doesn't work well with symlinks.

Even weirder was the fact that setting FastCgiIpcDir to 
/var/log/httpd/fastcgi also didn't work--just the fact that apache was 
symlinking to the same dir caused it not to like it.  However, when I 
changed FastCgiIpcDir to some other full path, such as /tmp, it worked 
just fine.

Anyway, I think the best solution to the problem is to get rid of the 
logs symlink in /etc/httpd and change it to a real directory.

Thanks again for all your help.

Carl
