## *process-pool-default-active-limit*

This variable provides the default value for the active-limit argument when a process pool is created (with, say, make-process-pool or ensure-default-process-pool). The initial value is `nil` to specify no limit at all.

Note that in some operating systems and hardware configurations creating too many processes may trigger an unrecoverable error. While `nil` is an unsatisfactory value, there is really no general value which applies in all cases because the desirable number of active processes depends on hardware, loading, OS details, and other information not really available when the value of this variable is originally set. Users should either determine a suitable value for this variable and set it themselves or always specify a value for the active-limit argument so the value of this variable is never actually used.

See Process pools in multiprocessing.htm for more information on process pools.
