Fix planned in 16.3.3
Since 16.3.0, a dead lock can occur when importing variables other than ‘Internal’. The issue manifests itself with a freeze during Application Architect generation or synchronization, while using a Smart Generator or the Xml Generic Import directly with the XmlImporter.exe command line. A forced exit of PcVue occurs after the 10-minute watchdog timeout.
Recommendation: 
Product users who cannot wait for the fix should roll-back to 16.2.5.
