In some traffic situations, TMM can excessively buffer client data instead of closing the TCP window. This buffering occurs based on internal race conditions that are not directly controllable. This occurs only when the BIG-IP is providing SSL termination or origination. In extreme circumstances with a slow connection, this could ultimately lead to out of memory situations.
Increased memory usage, possibly leading to tmm crashing.
The virtual must be providing SSL termination and/or origination.
None
Flow control through SSL is consistent and no longer leaves the chain misordered on flow control.
