 This most likely happens due to missconfiguration of components domain names.

Problem again relates to processing packet over broken connection (s2s here) and (seemingly) trying to re-deliver those packets.

Most likely a concurrency issue: this particular packet seem to be removed from waitingPackets queue (below line is after .poll())

[2020-08-30 05:10:11:702] [FINEST  ] [              in_1-s2s ] XMPPIOService.processWaitingPackets(): CID: null, null, type: accept, Socket: nullSocket[unconnected], jid: null, authenticated: false, SENT: [stream:features][starttls xmlns=&quot;urn:ietf:params:xml:ns:xmpp-tls&quot;/][dialback xmlns=&quot;urn:xmpp:features:dialback&quot;/][/stream:features]

Yet the exception is thrown on writeRawData() method:

at tigase.xmpp.XMPPIOService.writeRawData(XMPPIOService.java:276)
at tigase.xmpp.XMPPIOService.processWaitingPackets(XMPPIOService.java:236)

But probably due to concurrency it manages to get slated for re-delivery in tigase.server.ConnectionManager#serviceStopped.

As a fix I modified tigase.server.xmppserver.S2SConnectionManager#processUndeliveredPacket to ignore re-delivery of stream:features as it doesn't make much sense here and added more debug information.
