Why does AutoCAD and Revit crash every 15 minutes?
To resolve this, install the Vault 2019.1.1 update (requires 2019.1) on the server first then on the Vault clients. This will also address several stability and performance issues for the add-ins within AutoCAD, Inventor and Revit. Always ensure that a successful backup has been performed before applying any updates.
