Hi All,

I'm developing a new module for mod_perl 1.27, and I'm noticing that some code is getting executed twice when the Apache server starts up.

It was supposed to be fixed in 1.25_01:

=item 1.25_01 - July 6, 2001
...
fix double-loading bug of Perl{Require,Module}s at startup time

Here is the diff:

Indeed, that's the workaround that was added originaly to cure the above problem. Perhaps you can play with httpd_conf and see why it doesn't work for you. I know that several people have reported that they still had this problem since 1.26 was released.
