The standard
multiprocessing
lib has some issues mainly in Mac environment. Also, in Linux environment, too small system resources cause CodeChecker analyzer processes hang:If the maximum number of processes (
ulimit -u
) is too small, then allocating a process pool with the standardmultiprocessing
lib raises a RuntimeError that can't be handled. Withmultiprocess
lib another kind of exception is thrown, but the process itself doesn't hang.
