Lwip version 1.4.1
Processor STM32F107
I have been trying to track down a memory leak I am suffering on the PBUF_POOL. The problem doesn’t occur regularly, from the addresses involved I think it may be people probing open ports in the network.
I can provide the debug output if someone would like to see it, but essentially, the tcp connection is closed in state ESTABLISHED. Tcp_close_shutdown is run, it isn’t being caught by the initial if statement at the top of the function, rather it goes into the switch statement, runs tcp_send_fin, set the state to FIN_WAIT_1 and it is never referenced again.
Have I followed this through correctly, and if so what needs to be done to correct this behaviour?
Thanks
