I just got this update from the jira system on SVC-972, about how sim-to-sim teleports frequently end in a disconnect. Jake Linden is on the case and is requesting help in tracking the issue to see if his hunch is correct (Also, please vote for the issue if you haven't already):

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

Ok.

I now know exactly what is going wrong - still a little fuzzy on the why, but I'm zeroing in.

Here's what the problem is.

There's a particular message that gets sent from the originating sim to the client when either a teleport / region crossing has been completed successfully (ie the originating sim has contacted the destination sim, the agent has been passed across and then deleted from the originating sim).

This message contains information for the client to talk to the new sim.

This message is getting dropped.

What happens is that the client already knows a teleport is in transit and dumps out the old region information internally after the teleport times out, but doesn't have replacement region information, in which case it considers you logged out and, well, logs you out.

Thats what is happening.

Now, why is this message getting dropped?
Well, it's going via a new system - an HTTPS driven TCP/IP system that encrypts the information since some of the new server information we send to the client we want to keep encrypted.

This system is dropped the message in one of three possible places.

Either in the Simulator sending the message out to the client, in transport on it's way to the client (which is why when you guys turn off TCP/IP on your routers you get the same error) or in the code on the client that takes the incoming TCP/IP message and then fakes a UDP call so the same code that *used* to talk to the UDP stream is called. We know the actual code that runs when the message is received is not being called because it dumps out text to the logs and all the logs you guys have posted is missing this text - ergo that function is not being called.

I have a suspicion it's in the simulator side - what I need is one of you guys that is seeing this to ping me online if you see me, since I need to watch the logs of the sim you are teleporting from where the failure occurs and look for a specific message. If I see that message, then I know my hunch is correct. If I don't, then we need to look further down the pipe.

I'm going to be online tomorrow (the 26th of Feb) looking for people who are having the teleport fail there and then with this error.

Just wanted you to know that progress is being made.

Just unearthed this blast from the past while looking to see if there actually HAD been any progress on this - oh February, how optimistic you were.

Is there still a source for a DL of 1.18.3? I could have sworn I had a link to it for trapped people to try, but can't find it now.

*ETA* http://jira.secondlife.com/browse/SVC-1457 it's in there if anyone else is looking for it.
*ETA2* ...but it can't be used anymore so there goes that "fix"

this seems to mostly affect Linux users though, not so much for windows.

linux 1.20.15: teleport = disconnect, if teleport is friend = disconnect. reconnect in sim teleported to

Windows 1.20.15 = no problems.

*shrugs*

I have not personally experienced the disconnect-on-teleport problem in several months. It appears some people are still suffering though. I think it's a different root problem now, with the same end result.

Oh well as long as Windows is OK... :P

I think mostly it effects people that are too stubborn or overcommitted to just dump the program and move on with their lives.

I've had two in the last month, no sim crossings at all by TP or on foot - mac people, yes, but their credit cards are just as valid as the next guy's. One just gave up, another tried everything I could pull out of JIRA and stayed - he still can't use it from home unless he wants to stay put. Neither could be persuaded to submit a report.

The longer it goes the fewer reports it'll get even if it isn't fixed - it's one thing to submit a ticket if you know perfectly well it worked fine yesterday and you don't want to give it up, it's quite another if it NEVER works properly.

Might well have been multiple problems with the same symptom but at least one of them definitely still exists.
