if you have a 7.0 SMP (8 way if possible) box and can stand a little down time, I'm looking for someone to test the following: This snippet may freeze the process after a while: #include <sys/types.h> #include <unistd.h> #include <pthread.h> void *forker (void *arg) { while (1) { pid_t pid = fork(); if (pid == 0) { exit(0); } else if (pid > 0) { int status; waitpid(pid, &status, 0); } else { printf("Fork failed\n"); abort(); } } } int main(void) { int i = 0; for (i = 0; i < 4; i++) { pthread_t thr; pthread_create(&thr, NULL, forker, NULL); pthread_detach(thr); } while(1) sleep(1000); } with the following patch applied: http://www.freebsd.org/~julian/kse-7.diff it should not. can someone with a 7.0 machine please confirm this? (requires a recompile of libkse and linking with libkse.) (you could call it something else for the test).
