For one thing, we don'= t use ntpdate, we use the "ntpd -g -q" alternative. Secondly, for us ntpd i= s hanging 100% of the time when run via a Python thread class. The exceptio= n is Python 2.5.1; this succeeds 100% of the time. >=20 > >Peter, what platform You use? I use MIPS BCM5354. >=20 > We have a variety of 1U and 3U boxes. They all hang the same way. Very wild guess, check the process signal mask of the child for both methods of spawning. --4Ckj6UjgE2iN1+kY Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (FreeBSD) iEYEARECAAYFAkuGlMQACgkQC3+MBN1Mb4iFjwCg3qaheJHGXE6EJcq3Gjpd38Xp vRAAn3zxTwK0yrbjYlbV8HklGZnCGJ7x =fEZL -----END PGP SIGNATURE----- --4Ckj6UjgE2iN1+kY--
