Wait, this is C++... so naturally it is not that simple.

Small bug in the Windows Title bar: the Decrement fires too often, and removes all character counts from the title bar. We need to move the decrement to the place where a real disconnect is happening.

I noticed after being online chatting for '30' minutes, everything locks up. I looked in the log a few minutes after I noticed the comms stopped working.

This is what the world was doing, it's no wonder things stop working. I'd really like to get this resolved.


Edit: This was my startup

Code: Select all

19:23:56.244 I UDP      New client connected from 68.98.218.5
19:23:56.244 I UDP      Received session request from 68.98.218.5 with connection ID 1355101545
So it was just under 30 mins.

I was able to reproduce this with local clients and what happened was after one of the connection dropped, sometimes the remaining client would just change what port it was using as it's source. The new client however never gets a session request or anything like that so we can't really reference it very well in code and it breaks a lot of things.

So we have to figure out if this is normal and there's just a packet the client sends out to let the server know, or more likely because of the timing it's reacting to something the server is doing. It's probably going to be socket related, but I don't know for sure.

Looks like the chunk info struct was null, probably another case of a bad chunk id getting passed around.

Seems to be right up top in the constructor. Should we check "info" before proceeding? I imagine halting a chunk load will leave everything in a bad state.

Code: Select all

ChunkServer::ChunkServer(ChunkInfo* info) {
?	if( !info )
?		return;
	SetChunkProperties(info);

I lied, actually that was from a zoning packet...so the coord values were not valid? It would be better to check info before constructing though and just DC the client that sent the request. x = -25 y = 3 it looks like.

double edit: Those values don't look terribly off from other chunk coords but we don't have that entry in the DB, would be nice if someone would tell us where they were zoning to when the crash happened.

According to the console, they were in Isle of Dawn, which covers the -25, 0/1/2 through -27, 0/1/2 square of 9 zones. -25, 3 sounds like the south chunk in the left-most column of the world. SOE has a "do not enter" packet, maybe Xinux can tell us which one. I guess it never occurred to me to run off the end of the world before. Ahh, players...

Put in a temporary fix for now just to stop the crash, if there's a packet that prevents the attempt at all that would be cool though.
