Bug ID 1116185: Removing multiple images simultaneously from the webUI causes an error

Last Modified: Apr 05, 2023

Affected Product(s):
F5OS F5OS, Velos(all modules)

Known Affected Versions:
F5OS-A 1.0.0, F5OS-A 1.0.1, F5OS-A 1.1.0, F5OS-A 1.1.1

Fixed In:
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.

Fix Information

The issue is fixed by improving the image removal process.
