Hmmmm. Here are my compile flags : CPPFLAGS : only some -I and -D flags CFLAGS : -D_THREAD_SAFE -pthread LDFLAGS : -lmilter -lkvm -lm -lpthread > have you tried 6.0? Yes. It presents the same behaviour. Either way, I've found it with 6.0, = and=20 tried back with previous versions till find when the change took place. > also, does the child do an exec() after forking? No. The child gets out the father loop and calls another initialisation f= unction. As It seemed to me that all father's threads are stopped in the forked pr= ocess,=20 this seemed to me not be a problem. Am I right ? The signal handler thread is launched by the following sequence of instru= ctions. sigemptyset(&set); sigaddset(&set, SIGHUP); sigaddset(&set, SIGTERM); sigaddset(&set, SIGINT); sigaddset(&set, SIGUSR1); sigaddset(&set, SIGUSR2); if ((r =3D pthread_sigmask(SIG_BLOCK, &set, NULL)) !=3D 0) { errno =3D r; LOG_SYS_ERROR("Couldn't mask signals"); } if ((r =3D pthread_create(&tid, NULL, filter_signal_handler, NULL)) !=3D= 0) LOG_SYS_ERROR("Error launching filter_signal_handler"); Thanks for your help.
