Description:
Bug ID 1470021: Increased TMM memory usage on standby unit after it loses a connection ... Last Modified: Apr 26, 2024 ... Symptoms ... TMM memory usage on a standby BIG-IP device might be substantially higher than the active device. ... Impact ... The standby device may not be able to take over traffic when failover occurs. ... Conditions ... Standby device with UDP mirroring traffic and datagram-load-balancing disabled. ... The standby does not have the flow in its table from the start. ... This might be do to one or more of the following: - The aggressive sweeper expired the flow, but the flow was still valid on the active unit. - "tmsh delete sys connection" was run on the standby to remove a flow that was still valid on the active unit. - The configuration was initially out of sync and the active had "mirror enabled" while the standby had "mirror disabled" on the virtual server and the configurations were brought in sync during the lifetime of the connection on the active unit.
