I have taken a look but couldn't find anything. The TCP stream also looks pretty okay 
until BIRD sends a FINand then RST repeatedly to which Routinator replies with ACK then 
comes the next RST, next ACK in reply and so forth unti the last RST and then 5s later the 
next connection comes up which ends up the same way after some data transferred.

Is someone willing to take a look the PCAP real quick as I am not able to figure out 
what's going on between the two. I would then share it.

Thank you so much!
