No errors in syslog. DC crew replaced hardware\cables - didn't help. ifconfig ix0 down && ifconfig ix0 up - resolves the issue immediately. Another workaround which looks like resolved the issue: ifconfig ix0 -rxcsum -rxcsum6 -txcsum -txcsum6 -lro -tso -vlanhwtso - no connection losses observed for > 24 hours after that. Is there some command I should run next time issue is observed to help iden= tify the root issue? Thanks. --=20 You are receiving this mail because: You are the assignee for the bug.=
