Are you caching those connections or re-opening a fresh one for every request?
And if the latter, are you *closing* the connection before returning the
queried data to the client? Are you sure, evidenced by monitoring the OS’s
open file handles counter?
You don’t say which OS this is, but if it’s Linux:
ls /proc/$(pidof my-dancer-program)/fd | wc -l

So you believe. Double-check.

That sure sounds like a leaked resource of some kind. I have you chasing DB
file handles. You say it isn’t leaked memory. If not either of those, then it
could be web sockets or any similar sort of thing.
