Bang on. The kernel tries to keep a pool of pages free for allocation during an interrupt. It can't swap during an interrupt. A few like that are harmless, the machine just dropped about 10 packets from your trace. Those drops as part of the TCP protocol cause the other end to slow sending to what you can take without drops
