I have an app using Class::DBI, hitting a Postgres database, running under mod_perl(1.0). Everything works fine unless there are relatively simultaneous attempts to fetch a given page, which fetches a Class::DBI object and displays it. When this happens, I get a DBI bind_col error: bind_col: column 2 is not a valid column (1..1) at /usr/local/lib/perl5/site_perl/5.8.0/i686-linux/DBI.pm line 1797The column in question varies, depending upon which class/db table is being accessed. It may be a DBIx::ContextualFetch problem, but the error is right out of the DBI xs stub. Again, this only occurs when there are simultaneous requests. Further debugging makes me think that different handler processes under mod_perl are getting the wrong database statement handles. Anyone have this problem with DBI and mod_perl? Jim
