Hi Alhad,
Maybe one reason.
Output driver overrun- packet are sending, but second packet overrun first.
Try do test with delay:
while(1) {
lwip_write();
delay(10ms);
}
Please, write about your system-hardware.

Any reason why this would happen?

Hi,
I am using LWIP 1.4.1 and we are seeing a situation where lwip_write()
blocks indefinitely.
We are using a tcp socket, connecting to a remote socket. and then calling
lip_write over and over.
lwip_socket();
lwip_connect()
while(1) {
lwip_write();
}
The server is the netcat command running on a mac host.
In what situation would something like this happen?
Would this result because of improper configs in our lwipopts.h file?
Is there a cap on the size of the data buffer being passed to lwip_write?
Thanks,
Alhad
