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
Med vänlig hälsning/Best Regards

Sorry about the version, I use
1.3.0,
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
