Crash upon login...

Alright, all of my characters load except for my hunter, who is in Thousand Needles. He is parked at the Freewind Post inn. Every time I load him, this happens.

Now, I did load my warrior in Camp T and he walked around with "find minerals" active and I saw plenty of ore, so it may just be something in Needles. I am going to walk my warrior down there and see what happens.

I confirmed this is a bug with the mineral system. I started south along the road from Camp T and it crashed.

So it isn't just Needles. This makes it impossible to keep a server up, so I set the priority to urgent.

This is most likely related to this commit:

[url]https://github.com/mangoszero/server/commit/989d66c62dcad884d361827b8cef1c12d421ad76[/url]

Seems like it. How would I remove just that commit with git? I am a novice with git. Cloning, pulling, pushing, I can do. testing by removing a single commit, not so much.

*UPDATE*

I figure it out, I think. I ran the following and am now rebuilding.
[code]
git rebase -p --onto 989d66c62dcad884d361827b8cef1c12d421ad76^ 989d66c62dcad884d361827b8cef1c12d421ad76
[/code]
If this fixes it, then there is something wrong with that commit.

Alright, after removing that commit I was able to play, but naturally no mineral deposits (ores) were spawning.

Thanks for the report.
I tried now to walk from camp t to tanaris without having any problems, can you tell me exact locations, were the crashes occour?

I cannot because it is random. My hunter is in Freewind Post and with that commit in my code, I cannot even login. Likewise, if I play my warrior and start walking south from Camp T, the server will crash somewhere between Camp T and The Great Lift. However, the exact location appears to vary. I can do some specific testing if you give me some direction as to what you need.

I guess you are using Linux?
I will try to recreate that bug on my Win system, does GM Mode change anything if on or off?

No, in fact I was in GM mode when I tried to run my Orc warrior from Camp T south. It crashed just south of Camp T. Yes, I use Linux for all of my server needs. After all a Windows Server License can be over $3,500!

I will investigate this further as soon as i find the time probably not before sunday.
Tested with GM mode enabled but no crash sadly.

No problem. I can easily shoot a video of this happening if you want. I know the server has crashed when NPCs and mobs stop spawning as I move south!
