Known Issues

Description

System:

  • The countdown dialog does not appear at the end of the software update
  • Litmus Edge activation fails if the edge device is shut down before the activation request is approved in Litmus Edge Manager
  • Expired licenses use more than 35% of the CPU
  • The API calls post /auth/v2/providers/config/test with the Advanced Directory configuration result in Server Error 500
  • The message shown when a template deployment fails does not tell the user which components had failed
  • If the device name is the same as the one that appears in the template, the template upload fails for the devices with the same configuration; the workaround is to edit the device names in the template file
  • An incorrect error message is shown when an external storage mount cannot be found
  • The error message shown when remote access fails is not user-friendly
  • Errors shown when applying MP templates are not user-friendly
  • Errors shown when an Active Directory test fails are not user-friendly
  • There is a discrepancy between the memory usage values shown on the Dashboard and on the System > Info pane
  • Software update from 3.0.1.0 dissolves all groups defined in the Analytics module
  • InfluxDB initialization for large databases is unstable (slow, with high CPU consumption)
  • Software upgrade is not supported on VirtualBox 6.1.x; upgrade attempt may result in a corrupted, unrecoverable appliance

DeviceHub:

  • The Modbus RTU Gen2 driver doesn't connect until the Gen1 driver is added
  • Incorrect events are shown after adding or uploading tags
  • The message interval increases after a PLC power-cycle when using the AB CompactLogix Ethernet FreeTag Gen2 driver
  • The OPC UA client does not connect to the server with the Basic256Sha256-SE security policy

Analytics:

  • Restoring from a backup file does not restore the device analytics
  • Processors that are manually moved to the right on the canvas erroneously re-align to the left
