Peter,
    Thanks for replying.  I don't think server load is a factor but  I 
will look into it.  What makes me think that load is probably not the 
cause is that  when there are no startup errors everything starts and 
runs as normal in the normal amount of time.  The problem occurs when 
one app fails during startup. For  unknown reasons Tomcat either does 
not get notified of the failure and is left some sort of waiting state 
or Tomcat gets hung trying to shutdown the failed app.

    Thanks again for replying,
    -=beeky
