Symptom

Dataloy crashes randomly on Windows 7/Windows Server 2008, but especially during startup or when when opening DDT module. The error tends to happen in ieEmbed.exe or rtutils.dll, but it might be elsewhere.

Cause

If DEP (Data Execution Protection) in Windows is enabled, it will interfere with Java Garbage Collection if it starts during a call to native code. These calls typically happen when getting a network connection and when opening the browser module.

Resolution

Exclude java.exe, javaw.exe and javaws.exe from DEP.

1. Click 'Start'
   
2. Right-click on 'Computer' and select 'Properties'
   
3. 'Select Advanced System settings'
   
4. Under 'Performance', click the 'Settings..' button
   
5. Select the 'Data Execution Prevention' tab
   
6. Click 'Add..' and add the files java.exe, javaw.exe and javaws.exe one by one. They are located in the Java installation directory or sometimes in WINDOWS/System32.
