Jabber protocol does not have any mechanism of reliable message
delivery. It entirely relies on the underlying TCP protocol (which is
unreliable too, by te way).
In case of network failure ejabberd (I guess not only ejabberd) can't
figure it out before some TCP timeout reaches. All messages sent
before that are lost.
