-------------------------------------------

             Summary: xmpp starttls problemcauses connection spew
                 Key: ASTERISK-24712
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-24712
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Resources/res_xmpp
    Affects Versions: 13.1.0, 13.0.2
         Environment: Linux with not-quite-corectly-installed openSSL
            Reporter: Matthias Urlichs


Three issues here.

(A) ERROR[27439]: res_xmpp.c:2556 in xmpp_client_requested_tls: TLS connection for client 'asterisk' cannot be established. OpenSSL initialization failed.
… so what exactly is the problem with initializing OpenSSL? do we get an error code or anything?

(B) Asterisk now immediately retries the connection attempt. Which is extremely anti-social. There should *always* be at least a linear, or even an exponential, back-off. This goes on indefinitely, except …

(C) ERROR[27439]: res_xmpp.c:3334 in xmpp_action_hook: xmpp_action_hook was called without a packet. This happens because the connection is closed by the server (you're flooding it, after all). Again, there is no back-off here, Asterisk immediately retries. And retries. And retries. By the time somebody notices the problem, the server has banned our IP.
