TCP connections stall or get dropped.
This usually happens with rateshaper or BWC enabled. Rarely could also happen with very lossy networks.
Under some network conditions especially with rateshaper enabled TCP connection could stall and ultimately get reset.
Properly manage re-transmissions after a tail drop by not not doing the exponential back-off. Reset the re-transmit timer for every partial ack received after a tail drop.
