Strange, intermittent error on website

When I load my wife's website, I occasionally get this strange error.  It vanishes once you refresh the page.

No operations allowed after connection closed.Connection was implicitly closed due to underlying exception/error: ** BEGIN NESTED EXCEPTION ** com.mysql.jdbc.CommunicationsException MESSAGE: Communications link failure due to underlying exception: ** BEGIN NESTED EXCEPTION ** java.net.SocketException MESSAGE: Software caused connection abort: socket write error STACKTRACE: java.net.SocketException: Software caused connection abort: socket write error at java.net.SocketOutputStream.socketWrite0(Native Method) at java.net.SocketOutputStream.socketWrite(SocketOutputStream.java:92) at java.net.SocketOutputStream.write(SocketOutputStream.java:136) at java.io.BufferedOutputStream.flushBuffer(BufferedOutputStream.java:65) at java.io.BufferedOutputStream.flush(BufferedOutputStream.java:123) at com.mysql.jdbc.MysqlIO.send(MysqlIO.java:2708) at com.mysql.jdbc.MysqlIO.sendCommand(MysqlIO.java:1604) at com.mysql.jdbc.MysqlIO.sqlQueryDirect(MysqlIO.java:1715) at com.mysql.jdbc.Connection.execSQ... The error occurred in C:\inetpub\vhosts\xpressdanceclasses.com\httpdocs\includes\header.cfm: line 2

Line 2 in header.cfm is the first line of this query (the line with the tag):

<cfquery name="blackout_dates" datasource="danceclass"> SELECT date_id         , date_off FROM blackout_dates </cfquery>

There is a LOT more to the error message, but it goes on and on and on, so I only pasted the top.

Anyone have any ideas as to what causes this?
