These messages appear because of too small rates or ceils for that classes (10:056B, 10:0578, ...). The implicit value for r2q is 10 and because of this the quantum value is too small. "Consider r2q change" it's a good ideea indeed ;-) You can take a look at devik's faq page, maybe it can help: http://luxik.cdi.cz/~devik/qos/htb/htbfaq.htm I don't know if that assertion has the same reason, I haven't noticed something like that in my logs. - -- Catalin Bucur mailto:cata@geniusnet.ro NOC @ Genius Network SRL - Galati - Romania -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) Comment: For info see http://www.gnupg.org iD8DBQE+LTU8pDe20wwI9oIRAo+HAJ90pY9n1oCHkxn4vT+JeTUtkr/3fwCffHlU uBMA2jrV0D1+P5moftwTjbA=yiPG -----END PGP SIGNATURE----- _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
