   * If the [[electronrt:instructions_for_use:instructions_for_use#network_local_data_cache|local or network disk cache]] becomes corrupted the application may crash at seemingly random places while calculations are computing. Clearing the [[electronrt:userguide:tutorials:all_tutorials#local_disk_cache|local disk cache]] within the application settings may help resolve unreproducible application crashes during calculations running.

+|  4  | All                          | Network patient database:<WRAP>
+  * If the application is set to use a [[electronrt:instructions_for_use:instructions_for_use#patient_database_file_storage|network patient directory]] shared with multiple users there may be a risk for 'database is locked' errors. This is due to the application using SQLite as it's database engine, which does not robustly support concurrent database users and reading/writing. While normal usage between one or two users may not pose a problem with this, having a significant number of users simultaneously accessing the network database or the following scenarios can cause the database to lock and throw this error:
+    * The application crashes or a network connection is interrupted during a SQL commit that allows the 'unlock' step to be missed OR
+    * The file is locked due to other network usage (e.g.: the file is in use by an external service such as an Antivirus scan, backup, etc) OR
+    * Multiple simultaneous users are attempting to read/write to the database at the same time
+  * If you receive the error "database is locked" you'll have to wait and try again once the database is unlocked

+|  5  | All                          | Application fails to load computed data: Under the following scenario, the application request and state handling has a known bug that results in computed data not loading within the application until a application close and re-open is performed:<WRAP>
+  * A patient/plan is opened and a user interface or task is opened
+  * Data begins computing (e.g.: a dose, beam, or device)
+  * While the data is computing the user navigates to another user interface within the application
+  * If the data finishes computing for the first user interface while the user is navigated to a new user interface and then the user navigates back to the first user interface, the application may not know the data is computed to display or use the results.
