Here is something odd .. I have just installed Tomcat 5.0.18 so that it does
not use IIS/JK2 like our 5.0.16 install.

I have deployed our webapp on it. The profiling between the 2 is totally
different.

On the 5.0.16 profile just 2 requests to the webapp made the heap profile have
a scale of 100-200MB being used. Now on 5.0.18 it is 10-30MB.

Also, all the dynamic graphs showing heap use, object use ad GC are all really
active and spiky whereas the 5.0.16 version was very linear and GC never seemed
to happen.

I'm no expert in this stuff but something has changed bigtime with this 5.0.18
install. They both use the same JVM too.
