Testing of new double region crossing fixes by Pepper Linden

I've been testing region crossings on a train with animats Resident, great improvements! However, we both agreed that the llAvatarOnSitTarget bug is still present. Please check the Blake Sea activity around 10:50 AM SLT.

Alistar Snook Yes. Big improvement. At the user level, the train driver avi has been running the little train without error for 11 hours now. But passenger avatars fall off after a few hours.
From my Sharpview viewer logs, I'm seeing many event poller HTTP errors. But there are always a lot of event poller HTTP errors. At one point, the event poll returned an HTTP 404 (bad link) error for the current region, which I have not seen before and is just wrong. That kicked my alt's connection off, but the avatar remained visible in other viewers that were logged in. Something similar happened to Pepper Linden's alt.
(Note that this all about the Blake Sea on the beta grid, aditi, which is running very new simulator code. If you comment here, please mention whether you're on the beta grid.)

animats Resident I think we should focus on the passenger side. If the train is modifiable, adding a debug script to check whether the seat is actually occupied, or if it falsely registers as occupied when it shouldn't be, would be crucial for providing accurate data and logs.

I've been flying in and out and driving around this square of sims for a few minutes now and it only failed to teleport me once but it never disconnected me so that's a win. I just watched a bunch of boats doing kind of the same thing and the only thing I noticed is that it took longer to teleport to the adjacent sim via the map than it did to cross into the next region. that might be a perception thing but that's how it looks to me. I haven't floated off into the distance with a vehicle yet ether other than the one failed to teleport message.

Tested with several fast ground-based vehicles. Normal sim crossings from one region to the next were very swift. No failures, very quick response, no unexpected behavior.
The only hiccup occurred when attempting to cross the four corners in the central plaza. In the complex interaction between four regions while also handling collisions with the plaza centerpiece and an avatar in said centerpiece, the car became unresponsive, though editable. My avatar was relocated to negative coordinates, which persisted after standing and teleporting to another location, but returned to normal after the car was autoreturned. However, I could only reproduce this once in another vehicle more capable of driving over the landscaping, the rest of the attempts saw no issues.

Kandy Tomorrow Where was this? Beta grid Ahern/Dore/Morris/Bonifacio corner (the only "plaza" where the new fix is running) or elsewhere?
Kandy Tomorrow
Yes, in and around the "infohub" there on Aditi. Mostly doing laps through the regions over the open terrain around it, but occasionally driving over the quadripoint in the bushes here.

Per a note from Pepper Linden, I tried today's latest simulator:
You are at 10.3, 1.4, 39.7 in Ahern located at simhost-08c9a0b5dbf45b71d.aditi
SLURL: secondlife://Aditi/secondlife/Ahern/10/1/40
(global coordinates 255,242.0, 256,513.0, 39.7)
Riders Test Channel 2026-07-29.30492424196
Drove round and round the Ahern/Morris/Dore/Bonifacio region corner on aditi for 20 minutes.
Zero failures.
One stall of about two seconds. Normal crossing stalls were shorter than yesterday. This is looking very good.This is with a passenger. The driver is in Firestorm and the passenger is in Sharpview. Sharpview is logging some errors, but those are normal region crossing events, as one region lets go and another picks up. I've never been able to do that many region crossings with a passenger before.
Longer testing needs a four sandbox corner where we can rez a train track or set up some kind of self-driving vehicle. Then this can go on automatic and run overnight.
This is huge progress.

Built a rail loop on aditi Blake Sea - Thunderer, and am running a train round and round, right through the region corner. So far, after 1.4 hours of testing, one crossing failure, at the region corner, between 2 PM and 2:10 PM SLT on 2026-08-03. Avatar came off, ended up in a clean stand, and the train then disappeared because object entry is turned off. Avatar was not in a broken state, just standing. Can't tell about the vehicle.
This is running now, doing about one corner crossing every 20 seconds, plus two other non-corner crossings. So, over 700 crossings per hour now. Good way to test automatically.

Disregard test results above. The test regions had been switched to a different simulator which lacked the double region crossing fix. More testing after some dev simulator branches are merged.

animats Resident: as of about an hour ago, Aditi Blake Sea regions should be back on Pepper's latest test build, 2026-07-29.30492424196

Maestro Linden Testing now.

Thank you so much for the feedback animats! I will take a look at the simulator logs, and see if we can tweak things to help with these scenarios.

Blake Sea - Jetsam has been unusable all day, every handoff fails. The other water sims in that area seem to be fine, though sometimes you have to loiter awhile for the client to connect to them while traveling.

Huns Valen Is "Blake Sea - Jetsam" giving trouble on the main grid (agni) or the beta grid (aditi)? This discussion is about tests going on over at the beta grid.
