Severity: 2-Critical


Devices remain out of sync and ASM REST/GUI becomes unresponsive. asm_config_server may create many unique PIDs


-- 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. -- Large number of asm_config_server processes increases host memory usage


-- A manual sync 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.
