Known Affected Versions:
F5OS-A 1.0.0, F5OS-A 1.0.1, F5OS-A 1.1.0, F5OS-A 1.1.1
F5OS-A 1.3.0, F5OS-A 1.2.0
Opened: Jun 16, 2022 Severity: 2-Critical
The image removal action handler takes the input and processes it one item at a time. From the CLI/RESTCONF interface, the user can provide one image at a time. But the webUI allows the user to select multiple images and click Delete to remove them in a single click. This was creating a backend handler issue that caused the image agent to crash.
In this situation, all subsequent image removal requests cause an error: "Error: application communication failure".
When multiple images are selected and processed for removal from the webUI.
The issue is fixed in F5OS-A 1.2.0. To avoid this situation in other releases of F5OS-A, the user must select one image at a time for deletion from the webUI. Restarting the image agent service recovers the system from this state.
The issue is fixed by improving the image removal process.
