Only on that one region server? Weird. Does this persist when you bounce it?

Bad disk or network?
Anything in the logs (HBase, HDFS, and System logs)?
HBase 0.94, still?
The easiest way to just kill the region servers, the others will pick up the
regions.

Any ideas on what could be wrong w/ this RS? The RS is not unusually busy.
Thanks,
