It's not really harmful, it just means the kernel was momentarily unable
to allocate memory to handle an incoming network packet. That packet
will get dropped, but the system should recover.
Not sure why it's allocating an order 2 chunk though, that is 16KB. Are
you using jumbo frames on the network?
