Received corrupted data(-54). Closing the connection.

[rcbandit2]

Hi,
  I'm working on a example with GnuTLS - ex-serv-x509.c. I made a loop insight the client which makes a connection with the server and sends 200 times simple string. The interesting part in when I type Ctrl+C and I kill the client I get this error on the server?

[root@localhost test]# ./server
Server ready. Listening to port '5556'.

- connection from 127.0.0.1, port 41441
- Handshake was completed

*** Received corrupted data(-54). Closing the connection.


[root@localhost test]#

Why the server crashes when I kill the client?

This is not a crash. This is an error from your server.
In your case gnutls propagated an error from recv() to
your server. Whether to accept more connections or exit
is up to your application.

In TLS it is recommended to terminate the sessions on
the TLS layer as in:
