[En-Nut-Discussion] Blocked NutTcpAccept ?

[Petr Odlozil]

Hello,

I have a simple application which accepts connections from a client and 
save accepted  sockets to a que. It sends then a message to the second 
thread.

  Second thread then takes theese sockets from the que and connects to 
another server and send the messages from the socket to it. This thread 
also sends the replies from the server back to that socket.

Everything works fine when the server is connected to the network.

When I disconnect the server, the thread awaiting connections from a 
client blocks and  doesn't accept any new connections.
Socket is correctly created, but it hangs on NutTcpAccept(). And the 
thread isn't resumed (it's still in the sleep state), when some client 
is trying to connect.

The second thread, which tries to connect to the server correctly 
evaluates that the server is not connected and then just waits for 
another message from the first thread.

Is it possible that NutTcpAccept() blocks somehow and doesn't receive 
any new incomming connections and how to avoid this ?

My platform is Ethernut 1.3,
Accepting thread has priority 32
and Sending thread has priority 42

Best Regards
