If your normal load is around 50% you shouldn't ever hit that limit.
Do you lock all memory used by your RT threads ?
If you don't and the system is configured for high swappiness
 this sort of thing could happen.
I'm routinely running big real-time convolution matrices without
problems, so it's certainly possible.
A world of exhaustive, reliable metadata would be an utopia.
It's also a pipe-dream, founded on self-delusion, nerd hubris
and hysterically inflated market opportunities. (Cory Doctorow)
