HI,
Well this is what I think. But I wonder if assert are handled correctly
in the stack ?
From what I see, nothing break when the assert happen. I do not need to
restart anything to get the stack continue after the cable was
reconnected to my router.

Hi,
from wiki
http://en.wikipedia.org/wiki/Assertion_%28software_development%29:
In computer programming
<http://en.wikipedia.org/wiki/Computer_programming>, an *assertion* is
a predicate <http://en.wikipedia.org/wiki/First-order_logic> (a
true--false statement) placed in a program to indicate that the
developer /thinks/ that the predicate is always true at that place. If
an assertion evaluates to false at run-time, an assertion failure
results, which typically causes execution to abort.
You should restart the stack. If you are doing everything correctly,
it could mean that there is a severe bug inside the lwip. Try to
upgrade to 1.4.1, try to trace the situation which modifies the
variables in the assertion and double check your code, e.g. using one
socket in different threads, calling netif functions without the
netifapi prefix, etc.
I'm already to 1.4.1, my bad.
I use only 1 socket in one thread.
Regards
Jonathan

Hi all,
We are working on a problem right now. I use lwip 1.4.0.
I have an LWIP_ASSERT("already writing or closing",
msg->conn->current_msg == NULL &&
msg->conn->write_offset == 0);
I think this happen when I have many pbuf ready to be sent, and I
loose the initernet. On the first send timeout, I try to close the
socket.
My question is what I sould do on LWIP_ASSERT ?
Should I just put some warning on my display and continue, or I
should stop something in the Lwip stack and reinitialise something ?
regards
Jonathan
