BIG-IP ASM(all modules)

Known Affected Versions:

Opened: Feb 12, 2021
Severity: 3-Major


Devices remain out of sync and ASM REST/GUI becomes unresponsive.


-- The device that is meant to receive the config sync never requests or receives it. -- The devices become unsynchronized which may cause unexpected traffic enforcement or dropped traffic. -- ASM GUI becomes unresponsive.


A manual sync/failover device group is configured and ASM sync is enabled. Sync pushes are typically performed in one direction, and then a sync attempt is made in the opposite direction.


Halting asm_config_server on the stuck device restores the working state and request a new sync.
