Crash - kern.ipc.nmbufs limit reached
-
All network interfaces went down with message
[zone: mbuf] kern.ipc.nmbufs limit reached
though the system itself did not crash and I rebooted it from the console.It is 2.2.6-RELEASE on Dell server with 40-Gbit Chelsio Chelsio T580-LP-CR network card.
cat /boot/loader.conf.local
kern.ipc.nmbclusters="1048576"
net.inet.tcp.tso=0
kern.ipc.nmbjumbop="524288"Any idea what could be done to prevent it from happening again?
