Additional Information

A session that waits for ClientReadhas completed processing the last query and is waiting for the client to send the next request.

How to reduce this wait

This is normal for sessions which are connected and not performing any queries or transactions. If you see the number of sessions in ClientRead increasing then look for sessions not being terminated correctly or for sessions not committing transactions correctly.
