D state means uninterruptible sleep, usually requiring a disk operation to complete before the task can continue. It is not bad to see these occasionally, especially if you are running programs that shuffle a lot of data between disks or between disk and network.
When there are lots of processes in D state, the load average will go up. The drives are not fast enough for the workload. A classic cause of this would be excessive swapping due to running out of RAM. But in your case it looks more like a drive (or driver) becomes unresponsive for some reason.
