https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=254147 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: vendor = 'Intel Corporation' device = 'Ethernet Controller 10G X550T' ix0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 media: Ethernet autoselect (1000baseT <full-duplex>) Config overrides: net.inet.tcp.hostcache.cachelimit="0" machdep.hyperthreading_allowed="0" net.inet.tcp.soreceive_stream="1" net.isr.maxthreads="-1" net.isr.bindthreads="1" dev.ix.0.fc=0 dev.ix.0.iflib.rx_budget=65535 dev.ix.1.iflib.rx_budget=65535 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 limits. 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 identify the root issue? Thanks. -- You are receiving this mail because: You are the assignee for the bug.home | help
