Re: Strange Error

Jerry,

Hi there - I'm the maintainer of DBD::mysql

The verbiage going to your log looks like what you would see if you set 
the DBI trace level to 2 or greater. I've double-checked my code and any 
debug I print is indeed only occurring in a block where if trace is set 
to 2 or greater it would show up.

I wonder if CGI::Application might set trace? Or what about any sort of 
Apache/mod_perl startup scripts that might set it - have you checked those?
