Are you really updating a clustered key?  That'd slow your updates waayyy 
doowwn.

Have you identified what query is causing this problem?

Ok the situation is:

When you use a clustered index, the information is PHYSICALLY stored in order 
on disk. By changing the clustered key, you are moving a heck of a lot of data 
around within your pages.... combine that with moving (updating)  large binary 
data types of text, ntext, or image columns,  the query engine doesn't like it 
at all.

Simple solution. break the query into two steps.

Sorry forgot to change the subject:

Does anyone know why this occurs and how to fix this?

java.sql.SQLException: [Macromedia][SQLServer JDBC Driver][SQLServer]The
query processor could not produce a query plan from the optimizer because a
query cannot update a text, ntext, or image column and a clustering key at
the same time.

Sometimes the above happens and sometimes it doesn't. Anyone seen or know
what this actually means?
