I think the default limit is the same, but BIND 9 is
substantially slower on single CPU machines, so maybe that is
why you hit the limit?

I think it was limited originally because it took a few bytes
per outstanding query, I guess it could lead to memory
exhaustion if the performance was poor or memory limited. Memory
probably isn't such an issue at a nickle per megabyte or
whatever we are at these days.
You might want to keep an eye on performance at peak load.
