Things turned out for this symptom so far are: - This occurs around once per 1-2 days. - Once it occurs, all of communications including ARP and IPv4 stop. - "ifconfig em0 down/up" can recover the interface. However, on doing "up" after "down" the following message was displayed: # ifconfig em0 up em0: Could not setup receive structures After trying it several times it worked. Then, the interface seemed back to normal for a couple of minutes, but it stopped again. I guess there is a kind of deadlock somewhere but not sure it is really related to the em(4) driver. I will continue to investigate anyway. -- Hiroki ----Security_Multipart(Sat_Dec__5_18_40_17_2009_401)-- Content-Type: application/pgp-signature Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (FreeBSD) iEYEABECAAYFAksaKoEACgkQTyzT2CeTzy1MSQCghpIUlLCtnoop67R1QCFc25Dd xFsAoNQgMeCp2fVpGVQheEYI/7JJG+05 =5joe -----END PGP SIGNATURE----- ----Security_Multipart(Sat_Dec__5_18_40_17_2009_401)----
