Make sure you are using full version of SQL and make sure its set for auto increment........
If you are using default SQL in same server then it will create this kind of issue due to event processing.
we are using Enterprise version with 30 GB of RAM
It is set for auto increment
Found out that because of observation mode all the application details are sent to the ePO .
i have disabled observation mode now every thing is fine.
I would like to understand how you are deploying App Control and provide suggestions.
Please message me your contact information so that I can setup a followup meeting.
