Adam: May I have the thread dumps and logs from the regionservers at DEBUG level? I'm a little stumped. It seems as though one or more of your servers has locked up. It could be a deadlock or it could be something like a write barrier coming down and not ever being raised (You'll see messages in the regionserver log on the barrier). If you post logs somewhere I can pull, I'll check 'em out. St.Ack
