Bug ID 2285073: AbandonedTaskSweep Removes Tasks Prematurely

Last Modified: Apr 24, 2026

Affected Product(s):
BIG-IP ASM(all modules)

Known Affected Versions:
17.0.0, 17.0.0.1, 17.0.0.2, 17.5.0, 17.5.1, 17.5.1.2, 17.5.1.3, 17.5.1.4, 17.5.1.5

Opened: Apr 20, 2026

Severity: 3-Major

Symptoms

When an asynchronous worker reaches a lifecycle limit for memory or calls handled, it hands its remaining task queue off to another worker. Some timing conditions exist where the AbandonedTaskSweep periodic job will remove an unfinished task (such as a BulkTask) before the new worker updates the status to finished.

Impact

When the update to the task fails, the impact is cosmetic, as the task was already successfully completed. The result of the task will not be retrievable.

Conditions

Normal operations.

Workaround

None
