https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D213257 freebsd@mcwest.org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |freebsd@mcwest.org --- Comment #10 from freebsd@mcwest.org --- ALTQ requires the legacy single-queue mode in the igb(4) driver, but it see= ms this mode is unstable with high-bandwidth traffic. However, ALTQ may still= be used by adding a queue to limit throughput through igb interfaces. For example, the following workaround has prevented crashes on my systems for t= he last six months: ## Limit bandwidth on internal interface to avoid igb driver bug altq on $int_if cbq bandwidth 404Mb queue { internal } queue internal bandwidth 99% priority 1 cbq(default red borrow) --=20 You are receiving this mail because: You are the assignee for the bug.=
