In fact I came up with another solution. I realized that since the problem was related to the process signal mask, instead of called ntpd directly, wrap it up in a C app that resets the signal mask to something that works. I have the following code: sigset_t set, oset; sigemptyset(&set); pthread_sigmask(SIG_SETMASK, &set, &oset); system("/usr/sbin/ntpd -g -q"); pthread_sigmask(SIG_SETMASK, &oset, NULL); I wrapped this up into a standalone app and call this from Python instead of calling ntpd directly. This solved the problem--no more hang. Thanks very much to Kostik Belousov for his "wild guess" that this was related to the process signal mask. His guess was dead on. _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
