https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D208409 --- Comment #11 from freebsd@mcwest.org --- (In reply to ncrogers from comment #10) Well said. I can confirm that there is a bug in the igb(4) driver when usi= ng the legacy single-queue mode, eventually causing the kernel to crash. Addi= ng a queue to limit throughput is an effective workaround. For example: ## 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) Note that this appears to be a bug in the driver, and not in ALTQ itself (a= nd hence should be a separate bug report). However, with this workaround in p= lace I have not seen any crashes in the last six months. --=20 You are receiving this mail because: You are the assignee for the bug.=
