Could you add a routine that checks
for "all PCB is in CLOSING state" and issue a reset to the micro?
Not a good solution for the long term
(obviously lwip needs fix), but it would at least keep the system available for
the short term.

Ok,
I found it
in my changelog
Still not working,
sometimes the last ack disappears and on close the pcb state is changed to
CLOSING, forever
After a while all
pcb is in CLOSING state and I have to reset the system

Ok, I have downloaded the latest cvs
head, but nothing was mentioned in the changelog
I shall start to test to see if it works

Hi,
the fix for this bug
is included in CVS head. I can't send you 'a fix' since I would have to create
one for your lwIP version (by backporting it to the version of lwIP you use).
You can either download a CVS version of lwIP ('pretty stable' at the moment...
- no guarantee for that, though!), wait until 1.3.0 is released, or backport it
yourself by looking at the latest diffs to tcp.c and tcp_in.c in WebCVS.

Simon -
Thanks
for confirming the bug. We'll put a patch in our code for now and will watch the
bug for the real fix. Let me know if I can help, I would have suggested a fix,
but I'm not familiar enough with the ooseq processing in the stack.
As
you can imagine this is eventually fatal -- especially for applications that
make / break a lot of TCP connections (we do a lot of HTTP GETs and POSTs and is
how we discovered it).
Thanks again -
Tom
