I have some igb devices nailed down to 100MBit, but I haven't tested. Since this problem also triggered a problem in SCTP, I looked at that first and came up with a patch for the drivers to have correctly in case of drops. However, with my fixes, the mbuf problems went away... I can revert my patches and try to figure you what is going on... The mbufs denied counter was already large after a reboot of the system, without any traffic (SCTP or anything else). Best regards Michael > > > -a >
