What can I do with this system value?

You may specify the number of threads that can compete at the same time for memory and processor resources. For all active subsystems, the sum of all threads running in all memory pools cannot exceed the value you specify. If a thread cannot be processed because the activity level has been reached, the thread waits until another thread reaches a time slice or a long wait. Possible values are 1 through 32767 or no maximum (*NOMAX).

The suggested setting is No maximum (*NOMAX).
