Error in pentaho.log: Invalid connection properties

Hi, please can someone help me:
here is the output of my pentaho.log.
ERROR [org.pentaho.platform.util.logging.Logger] misc-java.lang.String: MDXConnection.ERROR_0002 - Invalid connection properties: PoolNeeded=false; Locale=de_DE; Catalog=solution:/dc/Cube.xml; Provider=mondrian

The complete log is attached in this post.
How can I fix this error? What is the meening of "PoolNeeded=False"? Mondrian should use a connection Pool!
Many Thanks in advance
Ayhan
