Any time you deal with RTOS, on 8051 or other targets, the stack is the thing to take care of.

One of the prpblems with using a stack oriented RTOS is that is is harder to predict just how deep the stack needs to be/ will be under all conditions.

Of course you can use an RTOS that does not use the stack.
