Bug in Sun OS 3.4 tcp?

Does anyone know about a problem with tcp under Sun OS 3.4 where receiving
a packet with the maximum segment size option messes up the window?
Our Suns can talk find to each other, but when they receive data from
a machine that uses the MSS option, the connection eventually hangs
because the Sun never updates the window. I have tried using diff on
the 3.4 source and the 4.3bsd tcp and have found no substantial differences,
so this bug might exist in 4.3bsd also.
