[Pdns-users] pdns 3.2-rc* MySQL Connection Limit

I am giving the static 3.2-rc1-1-amd64 package a go for the TinyDNS
support (which seems to work fine from my testing). I launch multiple
instances of PowerDNS and use the generic MySQL backend and I noticed
that a single instance seems to chew up all available MySQL connections.
When I went back to 3.1 the connections returned back to normal. I am
wondering if there is a configuration option that lets me limit the
number of connections?
As an example here is my config that spawns a lot of connections with
3.2 but not 3.1:
The config was used on a fresh install of Debian squeeze with a new
database to test.
When I up the number of connections for MySQL to let it open as many as
it wants it seems to max out at 514.
I upgraded to test on the latest 3.2-rc4-1-amd64 package with the same
config as above (a couple of lines had to be commented such as
lazy-cursion and logfile) but that appears to have the same issue.
