Package: prosody Version: 0.9.12-1 Severity: serious Tags: patch stretch Prosody fails to intiate S2S connections when lua-event 0.4.3 is installed. This bug was already fixed in the 0.10 branch of prosody but is still present on Debian stretch (which is shipped with lua-event 0.4.3)
The fix can be found at https://prosody.im/issues/issue/555 Errors in the log are: May 27 13:47:24 adns warn DNS socket for 8.8.8.8 disconnected: connection timeout May 27 13:47:39 adns warn DNS socket for 8.8.4.4 disconnected: connection timeout May 27 13:47:59 adns warn DNS socket for 8.8.8.8 disconnected: connection timeout May 27 13:47:59 adns error Exhausted all 2 configured DNS servers, next lookup will try 8.8.4.4 again May 27 13:48:04 s2sout55ea3204b2d0 info Out of connection options, can't connect to jabber.linux.it May 27 13:48:04 s2sout55ea3204b2d0 info Sending error replies for 2 queued stanzas because of failed outgoing connection to jabber.linux.it The problem can either be resolved by backporting the fix or marking lua-event 0.4.3 as conflict (and remove it from the Recommended field). Marking this as serious bug because federation is an extreme important part of XMPP/Jabber --- System information. --- Architecture: Kernel: Linux 4.9.0-3-amd64 Debian Release: 9.0 500 testing-debug debug.mirrors.debian.org 500 testing httpredir.debian.org
