Comment (by starlight):

 Reading this ticket and #28089 a potential concern comes to mind.  In my
 experience the Linux kernel is fastidious in releasing skb memory when
 sockets close, which leads to the question: is an additional bug present
 in KIST where sockets are leaked?  For kernel memory consumption to grow
 unbounded while the relay daemon continues to function correctly, a socket
 leak or stranding would appear necessary.  I do not know this code and
 someone familiar with it would be in a better position to consider the
 possibility.
