suspicious and Message is not being delivered over that particular OID and
after agent is unable to respond to any further commands/quiries.

to zero so no more router solicitations are sent. I checked RFC 4861 and it
says that the host should send at least one solicitation in the case where an
advertisement is received prior to sending a solicitation.

    _______________________________________________________

Details:

We ran across a fairly esoteric issue with the LwIP socket implementation.

The issue stems from using a TCP socket as a server. If the client sends data
to the server and is done, the client sends a "FIN" with the last packet. As
with all network stacks, in LwIP this results in select() notifying the
application of data on the socket and then a EOF on the server side draining
the socket. This is the correct behavior. In this situation you see this in
the debug:

Reported on lwip-users by mfkexpress (around 18.11.2014): The IP6H_VTCFL_SET()
seems to have problems with shifting '6' left by 28 (on a 16-bit platform,
where the constant '6' would be a 16-bit signed int, I assume).

As per the Open group spec, I would expect an error to be returned when a new
connection fails the accept process:
