  Use Locking Mechanisms: Ensure that your processes are designed to handle locking appropriately. Implementing proper locking mechanisms can help prevent concurrent modifications.
  Error Handling: If you are developing custom applications or enhancements, ensure that you have proper error handling in place to manage such conflicts gracefully.
