around 500 (CLOSE_WAIT) connection

I have hadoop 1.1.1 and hbase 0.94.1. Around 300 region on each region server. Right after the cluster is started, before I do anything. There are already around 500 (CLOSE_WAIT) connection from regionserver process to Datanode process. Is that normal?

Seems there are a lot of bugs related to (CLOSE_WAIT) issue in jira, but most of them 1 years ago.

Best Regards,
