I have noticed some strange packets with the "Window size scaling factor: -1 (unknown)". Is this a buffer full problem? I am seeing this on both the source and destination intermittently.

Thanks for your help in advance,

It just means that Wireshark doesn't KNOW the scale factor, most likely because it hasn't seen the SYN / SYN/ACK packets (where the options are negotiated). -1 is an artifical value meaning "unknown". So no, it is not a buffer full problem.
