MySQL with KSE -- Unstable?

To get around what you're describing, you should tweak

kern.threads.max_threads_per_proc
and
kern.threads.max_groups_per_proc

The default on 5.2 is quite low.

Still, I have a feeling once you get this limit increased, you might
see a problem similar to the one I described.
