Stream TCP raw reassembly is leaking
Added by Peter Manev over 2 years ago.
Updated almost 2 years ago.
Description
(originally reported y Eric Leblond)
It seems we have a leak in memory when TCP raw reassembly is enabled. Raw reassembly memuse is always going up. When deactivating it, the leak is gone. The leak seems to affect the flow that get cleaned far slowly.
Application layer triggering raw reassembly on TX border is helping a lot to reduce memory usage.
Peter to create a reproducible setup with trex.

Wonder if this could be related to #4766. If a flow gets stuck before its stream memory is released it might start to add up.
@Eric Leblond do we clean up the flows stream/app-layer memory when we switch to bypass?
