I just rolled some new functionality into our production server (which runs on mod_perl) and I'm receiving errors from my use base statement, in which I'm using multiple inheritance to utilize a mix-in class. Here's what I'm seeing:

Could not process that_module in that_method: Can't multiply inherit %FIELDS at /usr/local/perl5.8.6/lib/5.8.6/base.pm line 103

I don't have a problem with this in development and I can't reproduce it even when I run my development server in mod_perl with just one child process (I'm thinking this is a mod_perl issue). I dug into base.pm to figure out what's going on and it seems there's a conflict with the %FIELDS hashes of the base classes. But I'm not doing anything with %FIELDS or using the fields pragma.

I'm not sure what other specific context would be useful short of posting thousands of lines of code and I can't post a simple example, as I can't reproduce this in development. I'm hoping someone has some wisdom on what tends to trigger this error.

Any help appreciated.
