It's hard to tell. It looks like your machine somehow ended up without free DMA pages a situation from which the pagedaemon hardly recovers. If this happens again, wait a couple of minutes because the pagedaemon might take some time to recover. If the kernel doesn't recover, could you try to enter ddb(4) and show the content of "ps /o", "show uvm" and "show bcstats". Thanks!
