Additional notes
(Please edit this page to include any of your own useful hints and tips for fixing this error.)
This error usually indicates the loss of one or more Fibre Channel frames, leading to out-of-order or out-of-sequence frames being received.
Things to try:
- If you are using FCoE in a virtual machine, check that your virtualisation software correctly handles high volumes of network traffic. In particular, some versions of qemu before version 0.11.1 can overflow the virtual NIC's whole receive queue in one shot, causing packets to be dropped before the virtual machine can execute a single instruction. (qemu is often used as a base for other virtualisation software, so this bug may affect you even if you don't think you are using qemu.)
