[CDBI] prepare_cached .. statement handle .. still Active errors

I've started seeing lots of errors like this on one machine:

prepare_cached(SELECT id, name, bio_database_id
FROM   coords
WHERE  name = ?
) statement handle DBIx::ContextualFetch::st=HASH(0x16eb970) still 
Active at /usr/lib/perl5/site_perl/5.8.5/Ima/DBI.pm line 391

The code runs fine on other machines. I saw hints in the archive that it 
may be a DBD::mysql problem, but that was with an older version. Does 
anybody recognize this?

My versions are:

DBI         1.51
DBD::mysql  3.0006
Ima::DBI    0.33
DBIx::ContextualFetch  1.02
Class::DBI  0.96

Thanks, Dave
