Cool VL Viewer forum

This has been going on for quite a while and it is driving me crazy trying to figure it out. When I TP many times the viewer closes. No warning, or anything it just closes. I land at my destination, everything looks fine, rezing as it should, then poof the whole thing closes. Usually about 10-20 seconds after I arrive. I may be able to teleport 4 or 5 times before it happens. Other times it will be the second or third. Although it seems to be more likely to happen if I have stayed in busy location (or otherwise rendering intensive) for a while.

I have tried different graphics settings, low draw distance (I usually run at 32 if I don't need to see what is in the distance). I have cleared cache, done everything I can think of. At one point I thought it was due to the system itself. But trying a totally different system (windows 7, Nvidia gpu only a year old) still has the same issue.

It must be a setting I am missing considering no one else is talking about this (at least I didn't find any when I did a search of the forums).

I thought perhaps it was timeout watchdog, but nope tried turning that off. I tried lowering bandwidth but that didn't make a difference either. The system isn't lagging so I have no idea what is causing it.

Any ideas?

Without the logs, I cannot know neither guess. Please, file a proper bug report, providing the necessary info.

I've been having cases of crashes like this for a while too: after some time online and visiting a few places, especially crowded ones, the viewer sometimes crashes right after a TP. Sadly, I'm on a Mac, so the latest version for me is not the very latest, but I just had one of these crashes, so I'm including the logs anyway. I had to keep only the second half of CoolVLViewer.log: the session had been quite long, and even zipped, it was exceeding the 64KB limit…

This is a known bug that got fixed in v1.26.22.11 (Fixed a crash bug in rigged mesh rebuild code that could sometimes occur on avatar de-rezzing (e.g. on TP)), and you are running v1.26.22.10...

Argh… Sorry for that… As I said, I'm on a Mac, and there's no build of version 1.26.22.11 there yet… I'll update as soon as it's available.

Thank you!

I have been working with this trying to track down if a particular setting makes the viewer more prone to crash or not (tried different network settings, cache settings, rendering settings, etc). In all of my tests it still happens about the 6th or 7th TP. But does vary a bit. And getting logs for this particular one has been difficult. I have tried it on 4 different machines with different operating systems (Windows Vista, 7, 8) with different video cards and all have the same results. So it is not something to do with a driver or particular video card or operating system. If I have been online for a while, it is almost a sure bet a TP will cause a crash, so I usually just relog as it is faster.

And now I see there was a bug fix in v1.26.22.11 for this kind of issue. I thought I had a newer version but it was the previous one (been a busy summer, didn't realize I had got so far behind). I downloaded 1.26.22.18 and it STILL does it.

I did manage to get a log today. Here is the teleport and crash after the TP:

It appears the crashes are all caused by the invalid face index. Perhaps if there is a texture failure the bug manages to bypass the fix done in .11? Maybe a coincidence I don't know.

The view to the user is still:
After the 6th or 7th Teleport the viewer closes. 6 or 7 is more common crash point now, but it does vary a bit. The longer you are in a sim without teleporting the more likely a crash will happen when you do. Especially if the area is an active one (club, popular store, etc). At least in my tests.
3 seconds after the teleport status bar leaves and you see the new location, the viewer closes/crashes The avatar usually has just landed on the ground when poof the viewer closes. If the sim is slow, their feet may not touch the ground before the crash. It happens in both crowded areas and empty ones.

I TP a lot (way more than 7 times: more like 20 times and over) in every SL session and never encountered this crash with v1.26.22.18.

The log extract you give is alas insufficient to track down that bug. I need either a stack trace log (Linux) or a crash dump (Windows). Please, follow the instructions given in the rules for this bug report forum.

I figured it is not a common bug or there would have been more reports on it. But why I got it across several different machines is a mystery. Although that was with the older version.

I didn't include the dump because it was too big for here. I will try to get another that will fit.

For Windows crash dumps, simply zip CoolVLViewer.dmp and attach the zip file here: it will fit.

Fresh crash and this time it does fit. Was on the 8th teleport this time.
