Post subject:  Random crashes (was: Virtual Memory Warnings)
Since the last version I have been crashing too whenever there is lots of things going on like many people at an event and now It even crashes when logging into my own home. Not sure what's going on here.
It's been rather random though sometimes it works just fine and others it just crashes with no warning message at all. I'm running a 5950X with 32gb ram and a 3090 24gb so I should not be running out of memory unless
application has a severe memory hole. This latest issue might be SL being SL though but the random crashes before I believe was not.

I split your post as a new topic, since it was totally unrelated with the topic you posted it into...

Please, be specific, and provide logs and crash dump (or stack trace log).

Follow the bug reporting rules or I cannot do anything to diagnose and fix the issue you are seeing...

The log is missing... This is the crash dump, but I do not even know what version of the viewer it relates to, or when the viewer crashed (this is in the log).

Also, what is the last version working for you, etc ?... Please, follow the list of the required info to the letter.

Ok, hopefully these are the logs you need and this is for v1.28.2.65, 64 bits, Apr 9 2022 11:29:46. The last version that did not exhibit this behavior was v1.28.2.63 (stable branch).
It isn't really possible to provide any step by step reproduction procedure for this bug other than it appeared to happen when many people were present but then it suddenly started happen at home with just me there as well.

The crash indeed seems related with a change introduced in v1.28.2.64 ("Backported from LL's performance viewer a fix to rigged mesh bounding boxes"), though I am not 100% sure why it happens (I should have seen it happening, especially in the hours-long sessions I had since this change got introduced).

I might have a fix. I am currently compiling a test viewer for you to experiment with it and see if it fixes the crash for you... Will PM you the link to the package once it is ready.

Please, keep testing (and do not hesitate to stress it badly !). That bug is apparently due to an extremely rare race condition (a spatial bridge that gets invalidated during the function execution) requiring some specific environment (surrounding objects, worn meshes, etc), else I would have encountered it myself during my long lasting stress-testing sessions...
