Re: DBI 1.15+ establishes multiple connections under parent mod_perl process
I have traced it back to prepare_cached() (at least that is what I
notice).
Scott, try replacing your calls on startup with prepare() instead of
prepare_cached().
I was also able to eliminate the problem if I commented out the
following line in DBI.pm
# $dbh-STORE('CachedKids', $cache = {}) unless $cache; # line 1021
sub prepare_cached
Of course this is not a solution, but it may give someone else with more
knowledge enough to fix the problem. I will keep digging for answers.

Re: DBI 1.15+ establishes multiple connections under parent mod_perl process
But prepare_cached/prepare has nothing to do with multiple connections.
There were connect() changes made between DBI 1.14 and 1.15 but I'd need
people to look into it for me. Should be trivial to debug by enabling
DBI tracing and Apache::DBi debug.

no, I'm using prepare(). an earlier post thread of mine (php vs perl)
has a copy of the script I'm running in it.
I was also able to eliminate the problem if I commented out the
following line in DBI.pm
# $dbh-STORE('CachedKids', $cache = {}) unless $cache; # line 1021

I haven't tried this though
