In cases where their path isn't blocked as soon as I open up that area I get wave after wave chasing me down. I can't even get back into the same room as bone pile because they come out when i'm 3 rooms over and as soon as I kill one a few seconds later as I'm killing the second another appears. Even fully rested with iron weapons my stamina and damage aren't enough to combat an instant spawn swarm.

WTH is up with this!?!

That's just the way the spawners work... It checks to see if there are the set amount of mobs present and, if there aren't enough, new ones spawn to replace them. It's exactly the same thing for (as an example) the Grey Dwarf spawner.... or Skeleton spawner.

As mentioned by others, you can try to use arrows to destroy the spawner, and if that isn't possible, you might have to take a few hits while you run in and manually destroy the spawner. Of course, as always, make sure you have eaten the best foods and have proper meads and rest bonus before attempting to clear dungeons.
