This just happened while I was watching (for a change). Someone just logged into New Telon and the console shot some spam (which was fixed a while ago) and then crashed:

Linux bt:

If this is any help, it is always the same IP that crashes my world. If the player is watching these posts, please speak up as to what you are doing to cause this. Maybe something changed in the Live client?

edit: haha it's Odinzz Speak up, man! What's going on on your end that can help us solve this crash?

That's interesting that it is just that IP. I wonder if it is something with the character they created. They should try creating a new character and joining.

I'll take a look at this later as well if not resolved, but the ~~chunkserver pointer~~ is invalid it looks like.

EDIT:Unreal pointer..I'm losing my mind lol.

Lol ! Yeah its me ! And I didn't do anything I swear !
I just log in ..spin around and it boots me !
I dunno ...maybe it just doesn't like me : (

I will try a new toon and see if that does it too

ok made a new toon and i ran all over NT at what felt like 100 mph lol no problems ( the elevator doesnt work lol ) as soon as i chunked into the next zone to the north ( i forget what chunk it was) it dumped....

Thanks for checking that out Odinzz. It was likely the previous character. I'll do a character wipe soon as we get more code done and we'll start fresh. At least there's 1 more thing to try for testers.

As for Xen, if there's a way to trap that explosion, can we do that to prevent ending the world?

Yep no problem ! it was really kinda cool to run thru NT with almost NO LAG ! Great job so far everyone this is great stuff so glad to be a part of it !

Committed what should be a fix for this, the only way that pointer could go bad is if the channel index was > 1024 (max channel index). We were never closing channels on zoning, I added this in where we receive a HELLO request for a bitstream, this should be ok but Xen would know better. I didn't notice any ill effects from it so assuming it's good.

I'm really surprised we haven't run into this sooner. Yes, we should be calling CloseAllChannels() when a client zones, so that it can reset each channel to the defaults and set the actor pointer to NULL. Thanks Foof.
