Exactly what parameter should i be looking at?  i found only the 
following entries.  Could it be that i'm running into this maxActive limit?
   (20 concurrent users editing a page could be possible, 20 users 
concurrently requesting or saving a page would be very unlikely and very 
quickly resolved, 5000 concurrent users would not be possible)

   <target path="/daisy/datasource/datasource">
     <configuration>
...
       <maxActive>20</maxActive>
       <maxIdle>8</maxIdle>
       <minIdle>0</minIdle>
       <maxWait>5000</maxWait>
     </configuration>
   </target>

no, we're using a standard daisy 1.5.1, with the built in daisy 
authentication scheme.  The only customizations are the fact that we run 
daisy under tomcat and that we use non-default ports.

I'd also like to see where the connections are going but i'm not a big 
java debugger/devoloper so if that's possible please let me me how.

cu,

Tom
