Incorrect online status received by simulator when sending an IM while a user is logging out.

Sending an IM right as a user goes offline fires back an OnlineNotification right after the offline notification.
I assume this is a racing condition on the server side.
The issue comes from the fact this then leaves the user in a permanent online state on your end unless you relog / send another IM.
Example:
[11:34:14] Kalimaru: Gotta dash
[11:34:19] Willow (kalimaru) is offline.
[11:34:20] TrishAce: ok
[11:34:21] Willow (kalimaru) is online.
[11:45:35] TrishAce: <testing>
[11:45:35] Willow (kalimaru) is offline.
[11:45:35] User not online - message will be stored and delivered later.
In this example, the notice at 11:34:11 is wrong, the user went offline.
Sending an IM later (while they are offline) then correctly syncs the status as you see here

I'm not able to reproduce this with Second Life Release 26.4.0.37384746592 or 'Firestorm 7.2.5 (81788) Oct 19 2026 15:21:25 (64bit / AVX2-LTO) (Firestorm-Releasex64)' on Second Life Server 2026-09-28.36457939353 after several tries. I tried between two users who are friends and also between two users who are not friends.
The steps I followed were:
- UserA and UserB: login to different regions
- UserA and UserB: IM each other a few times - verify proper delivery
- UserA: Start typing an IM to UserB, but don'tsend it yet
- UserB: Send an IM to UserB, then immediatelyexit the viewer
- UserA: Immediately send a message to UserB, and note the results.
I saw the expected results, which are:
- UserA gets UserB's message from (4)
- If UserA and UserB are friends, UserA gets a 'UserB is Offline' presence update message, and UserB appears offline to UserA
- No matter how soon UserB sends clicks 'send' to send a message to UserA in (5), their IM is met with 'User not online - message will be stored and delivered later.'. If UserA and UserB are friends, there is no 'UserB is Online' message.
Here's a typical chat log from UserA's perspective:
[1:38 PM] Maestro Tester: bye2
[1:38 PM] Maestro Tester is Offline
[1:38 PM] Litmus Tester: again2
[1:38 PM] User not online - message will be stored and delivered later.
TrishAce Resident, I have a few questions for you:
- You appear to be using a pre-release/testing viewer build. Does this reproduce when you're using either Second Life Release 26.4.0.37384746592 or 'Firestorm 7.2.5 (81788) Oct 19 2026 15:21:25 (64bit / AVX2-LTO) (Firestorm-Releasex64)'?
- How consistent is this bug for you? Is it every time, half the time, or only on rare occasions?
- When you hit this bug, the 2 users are friends, correct?
- When you hit this bug, are the 2 users in the same region, in nearby regions (within draw distance for your viewers), or in distant regions?

1) I am able to repro on base firestorm and base LL viewer as well, I have experienced this bug with all versions of firestorm for the past ~3y (since I have been in SL, way before I was on custom builds), so this is not a new bug. For a quick sanity check, I have also repro'ed just now using my alt on SLV 26.5
2) Very reliably reproducible, if I prepare a message and send it immediately after the "is offline" shows up in chat, I am near-guaranteed to get a follow up "is online" notification. Enough that over the years, I am used to this bug enough that I sneak in an extra message in my IMs when I know it happened.
3) Yes, 2 friends, both with online status shared for both. (Can't say if I have noticed it with non-friends)
4) The repro I have just done was while in different regions (RC Ferrari, Luau, and earlier today it also happened on main channel) Given this is an older bug, it used to happen with older sim version as well. It also repros while in the same region. (I cannot see a difference there)

[4:04 PM] MikaelaSnuggler: asfasf
[4:04 PM] Trish is Online

The second message here was already typed in, as soon as "is offline" came in, I sent it from my alt and then the "is online" message popped up immediately.
On Trish (account logging out), I could see my viewer was still shutting down (not fully closed yet), when my alt saw the "Is Online" notification.
Then the online status remained while I am effectively offline on Trish. I had to send another message for it to sync (as shown in the original chat log example)
I have attached a clip of the repro while in different regions and one while in the same region.
A possible 'dirty' viewer workaround at the moment is to refetch the online status after sending an IM and receiving "is online" right after.
