CGI and PL suddenly stopped working

[momentsofclarity]

Hello,

For an as yet determined reason, cgi and perl scripts suddenly stopped
working on my web server. Up until now (about 1 year) all has been
working just fine. I have tried all of the following with no joy...

-confirmed permissions on scripts, directories.
-confirmed proper ExecCGI arguments in httpd.conf
-chmod 777 scripts and directories (with suexec OFF)
-chmod +x /usr/bin/suidperl (suggested by a user on another mail list)
-deleted and relinked /usr/bin/perl to /usr/bin/perl5

Scripts run ok from the command line but only as root. If logged in as
the web user (apache), I get a "bad interpreter: Permission denied".
The browser message is the ever mysterious "500 Internal Server error".

Error logs just say "[error] (13)Permission denied: exec of
/path/to/test.pl failed".

Server info below:

kernel is 2.4.18-6mdk
Perl -v is v5.6.1
httpd -V is:

What am I missing?

Thanks.

Please note that web server configuration and OS issues are off-topic for

A short, simple CGI script that exhibits the problem.

That way, I would not have to ask if the path to perl is correctly
specified.

If it looks correct, did you transfer these files from a Windows computer
using binary ftp?

This points to a permissions or path problem.

Have you tried the following when running as a non-root user:

% which perl
% perl -v

And seeing that the results are what you expect?
