What is the reason of this?
It's normal in a system under load, the kernel can't always allocate memory when requested by the driver. The result is that RX frames will be dropped as the driver reuses an existing mbuf, a response taken by many other drivers. If you notice rapid increases during certain system operations then you should consider increasing the amount of system memory.
