WEBDAV and HEAP errors on 3.0Stable

I started over with 3.0stable hoping that my problems with getting this heap space to work would be fixed.

The installation on xp went smoothly and I was able to boot up alfresco.  I then set up a massive localhost webdav transfer, and after 15 min to half hour, I got my heap space "out of memory" errors. 

Here is my Alfresco.log

Caused by: java.lang.OutOfMemoryError: Java heap space

After I had this problem I went to the 3.0stable installation guide and on page 43, I saw this:

JVM settings
Alfresco generates a high proportion of temporary objects, both in client threads as well as in the
background processes. In order to reduce the number of temporary objects into the OldGen portion of the
heap, you need to set the NewSize option.
The following settings reduced the garbage collections and revealed (with GC printing and JMX tracing)
that the OldGen was not growing noticeably over and above the permanent space allocated for caches.
Cache sizes are still estimated top out around 520M. The StackSize should also be generously set to 1M.
So, for a typical 32 bit installation:
Given that the OldGen is composed primarily of cache data of up to about 520M, at least 1GB should be
reserved for OldGen. Once -Xmx increases, the OldGen can be increased to 2G. 512M should be left as
a buffer to account for miscellaneous (PermGen, and so on). So the following variations might be applied:
-Xmx2G -Xms1G -XX:NewSIze=512M (OldGen at least 1G)
-Xmx3G -Xms1G -XX:NewSize=512M (OldGen at least 2G)
-Xmx4G -Xms2G -XX:NewSize=1G (OldGen at least 2.5G)
-Xmx6G -Xms3G -XX:NewSize=2G (OldGen at least 3.5G)
-Xmx8G -Xms4G -XX:NewSize=3G (OldGen at least 4.5G)

Following those instructions, I changed the set JAVA_OPTS line in my alfresco.bat to:

set JAVA_OPTS=-server -Xcomp -Xbatch -Xss1024K -Xms1G -Xmx2G -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:NewSize=512m -XX:MaxPermSize=128M -XX:CMSInitiatingOccupancyFraction=80

Now alfresco will not even boot up.  All i get in the command prompt is
Starting Tomcat…
Using CATALINA_BASE:  C:\Alfresco\tomcat
USING CATALINA_HOME: C:\Alfresco\tomcat (etc…)

And then I get a flash of another command prompt which disappears and that's it.  Please help.
