[erlang-questions] tcp active mode connection with http packet sometimes gives tcp packets?

We are using a locally modified mochiweb that uses active mode (active,
true).  Mochiweb uses the http packet mode.

Occasionally, the server is getting a "tcp" packet instead of an "http"
packet.  The tcp packet contains the request line and headers.  One problem,
which we already fixed, is that we were setting active mode true and http
packet mode in two different places of the code.  Moving the two together
(either in the socket options for the listener socket, or after the socket
is accepted) reduced the frequency of the problem, but we're still seeing
"tcp" packets on occasion.

This occurs in both R12B3 and R12B4 on MacOSX and Linux.

Has anyone else seen a problem like this?
