Thank you Ryan and Ron, very good info. But there is a possible need for this process. Since the XML export can create such a report...many clients can assume that there is a possible way for the tool to do this a more streamlined way.
I located the file to modify for the XML export size:
/opt/Vontu/Protect/config/Manager.properties
Change setting:
com.vontu.manager.maxshowallincidents=10000
and
com.vontu.manager.maxautodistributionincidents=10000
Then
Restart Vontu services.
