For sudden, I'm fairly sure a packet is sent.
For not-so-sudden (eg timeouts), SL itself says something is wrong after
about five minutes. I believe there is a test ping packet in the
protocol.txt near the top. It's probably sent every little while.

That sounds like a good plan. This probably will not catch server crashes,
however, as no KickUser packet would be sent. As UDP is connectionless, the
only way to detect such a crash is to issue a ping style packet every so
often, or listen for such ping packets if the server already sends them. Do
we have any information on the method the official client uses to detect a
sudden server disconnection?

After being idle for a few hours (somewhere between 4 and 5 perhaps)
libsecondlife received an unsolicited event in the form of a KickUser
packet
(reported erroneously as a duplicate packet). This, and all other events
that would indicate a disconnection, should be handled in libsecondlife by
reporting the loss of connection via a callback and allowing a
reconnection
by the application if desired.
Information on such disconnections would be useful to the application, so
I
would suggest not handling it completely behind the scenes with an
automatic
reconnection. Reporting with a callback and making sure the library is in
a
state where it can cleanly connect again through the normal login process
are the important things.
Thoughts?

I was just talking about this yesterday. The idea was to automatically
disconnect everything internally and reset state, then fire a
DisconnectEvent if there's a registered client handler.
