The question was about *enterprise* deployment, which raises two issues: 1) most vendors are waiting for customer IPv6 demand before implementing support (or fixing bugs) - chicken and egg problem. 2) I don't know many enterprises running production software less than a year (or more) old. In the meantime, the network engineers struggling with this stuff need workarounds (like the tuning parameters you and others have mentioned). -- Harald
