I was monitoring for 1 week after replacing the kernel of 8.0-STABLE with 8.0R. Frequency of the symptom was reduced, but occurred once in 2-3 days. So it is reproducible on 8.0R, too. Just after the symptom occurred, dev.em.[01].debug showed the following: Dec 17 16:50:03 pool kernel: em0: Std mbuf failed = 0 Dec 17 16:50:03 pool kernel: em0: Std mbuf cluster failed = 9612 Dec 17 16:50:12 pool kernel: em1: Std mbuf failed = 0 Dec 17 16:50:12 pool kernel: em1: Std mbuf cluster failed = 15183 The other numbers look normal to me. dev.em.[01].stats reported almost all of the counters other than "Good Packets" are zero. Doing ifconfig down/up could make it work again, sending/receiving 10 packets or so it stopped. -- Hiroki ----Security_Multipart(Sun_Dec_20_05_37_57_2009_112)-- Content-Type: application/pgp-signature Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (FreeBSD) iEYEABECAAYFAkstOaUACgkQTyzT2CeTzy1OdwCfYdEoBvNvgm0taCnV4ay0ehDC rqcAmwVN1wIt6XP5i1FtFQ4W8BnA+XTq =i5jb -----END PGP SIGNATURE----- ----Security_Multipart(Sun_Dec_20_05_37_57_2009_112)----
