https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D254147 Bug ID: 254147 Summary: No buffer space available error on NIC Intel 10G X550T Product: Base System Version: 12.2-RELEASE Hardware: amd64 OS: Any Status: New Keywords: IntelNetworking Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: robert.ayrapetyan@gmail.com Configuration: Server: Dell R740XD NIC:=20=20=20=20=20 vendor =3D 'Intel Corporation' device =3D 'Ethernet Controller 10G X550T' ix0:=20 flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 media: Ethernet autoselect (1000baseT <full-duplex>) Config overrides: net.inet.tcp.hostcache.cachelimit=3D"0" machdep.hyperthreading_allowed=3D"0" net.inet.tcp.soreceive_stream=3D"1" net.isr.maxthreads=3D"-1" net.isr.bindthreads=3D"1" dev.ix.0.fc=3D0 dev.ix.0.iflib.rx_budget=3D65535 dev.ix.1.iflib.rx_budget=3D65535 After certain amount of time (2-8 hours) under a constant network load ~ 1Gbit\s, observing a loss of connection and any ping\traceroute end up with= "No buffer space available" error. netstat -m \ netstat -s output looks normal, all values are way beyond limi= ts. 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.=
