Dear all
After a week of debugging I finally find the issue. The problem is related to
priority in pcb.
Taking a deep look I saw that the priority in the stack 1.4.1 is change, in
particular:
Tcp_alloc return e pcb with a prior equal to the prior passed in input.
Tcp_listen_with_backlog return e pcb with a prior equal to the pcb.prior passed
in input.
This two changes lead to a sporadic RST ACK call from the kill_prio routine.
Finally I fix this issue removing the equal condition in the kill_prio function.
Best regards
Mattia Settin
