Limitations

1 min

The following limitations have been identified. When they are resolved, they will be reported in the latest Product Updates under Resolved Issues.

Description
DeviceHub: In the Create Browse Task dialog, the OPC UA Client Advanced driver's exclusion list checkboxes display on one line instead of in a list when browsing for tags. In grid view, IP Address, Port, or Station ID may not display in device cards. Refresh the page to show the missing values. DeviceHub user role permissions cannot be modified after they are saved. As a workaround, remove and recreate the role.
Analytics: Memory usage can remain high after deleting a TensorFlow processor. Belden Horizon Data Operations validates models only for archive format. Belden Horizon Data Operations does not verify that a model is loadable, or that the Input/Output operation names configured on the TensorFlow processor exist in the model's signatures. The processor saves without error, and any mismatch surfaces only as a load-time error when the source is enabled. As a workaround, run saved_model_cli show --dir <model_dir> --all to confirm the exact operation names before configuring the processor. Names are case sensitive and must come from the same signature. FileReader processor is unable to read files that are generated from Flows Manager. As a workaround, in Flows use the exec node to run chmod commands to update file and directory access. The first flow created in Flows Manager cannot be stopped or restarted in Safe Mode.
Integration: CSV imports incorrectly allow topic names that end with trailing dots. After upgrading to 4.0.16, Gen 2 connectors might start in a disabled state and require you to manually enable them. If the target disk for a PostgreSQL Gen 1 connector fills up, the connector may not recover on its own once space is freed. This does not affect the PostgreSQL Gen 2 connector. For Gen 1 connectors, corrupted buffer data after an unexpected shutdown can affect specific connectors' persistent storage. As a workaround, purge the persistent storage data. Updating the Bulk Insert Count from 0 to any other value causes connectors to enter a failed state. A bulk operation limit of 1000 exceeded error message displays when performing a bulk edit on less than 100 subscriptions.
OPC UA: When two nodes in different paths share the same name or ID, deleting or renaming one can instead incorrectly apply to the other. In addition, no error message displays.
System: After a system reset of an .iso deployment, certain services (such as DeviceHub API, Analytics API, and Message Broker) fail to initialize and remain in a failed state regardless of subsequent reboots. LDAP searches can return an excessive number of records resulting in a Size Limit Exceeded error. Importing a template with multiple connectors fails when a configuration issue occurred with one component.
