Known Behavior in Contrail Release 3.0.3.5
- 1716308 When the head fragment is received in the vRouter, the head fragment is enqueued to the assembler immediately upon arrival. The flow is created as hold flow and then trapped to agent. If fragments corresponding to this head fragment are already in the assembler or if new fragments arrive immediately after head fragment, the assembler releases them to flow module. If agent does not write flow action by the time the assembler releases fragments to flow module, fragments get enqueued in hold queue. As only maximum of three fragments are enqueued in holdq, rest of the fragments from the assembler gets dropped in the flow module. This leads to the whole packet being dropped on the receive side leading to first packet loss.
