I am curious as to why you are using DBI->connect_cached instead of just DBI->connect?

Why this?: 

$dbh->disconnect or warn "Disconnection failed: $DBI::errstr\n";
sleep(5);
$dbh = DBI->connect_cached(@connection) or die;

I read the following:

connect_cached is like connect, except that the database handle returned is also stored in a hash associated with the given parameters. If another call is made to connect_cached with the same parameter values, then the corresponding cached $dbh will be returned if it is still valid. The cached database handle is replaced with a new connection if it has been disconnected or if the ping method fails.

Caching can be useful in some applications, but it can also cause problems and should be used with care. The exact behavior of this method is liable to change, so if you intend to use it in any production applications you should discuss your needs on the dbi-users mailing list.

I don't see any need to drop your db connection and then re-connect. I recommend to ditch this connect_cached method. Connect once without caching and stay connected. There could be some glitch with this connect_cached method that is screwing things up? Stuff like "but it can also cause problems and should be used with care." are red flags to me.
