any ideas?

[lfxgroove]

This might be fixed "by itself" when going through what coverity scan has to say about zero. Does this always happen or just at times? And does it only happen when using the shutdown command? Also, do you close it from the console window or via chat in wow? (don't remember if that's possible, but it's worth asking)

[kupix]

will see what coverity "says". it happens every time. i'm using shutdown command from console window, not from client

[wolverine]

First off, I always treat my server as if it was a live server for Blizzard. I use

.server shutdown 30 0

I don't know if that second number helps any, but in windows, you have to make sure that the exit code is a 0 or windows freaks out and tries to debug the program. At least on my computer.

Now, as for the actual error log...

It looks like your debugger is trying to track back to the library files that are being reference at the time of the crash. As for the invalid pointer, I have gotten similar errors when I am trying to actually start mangosd. Once, there was a bad push on the repo and when I ran mangosd it would give me an error about a missing dll which actually did compile but was not being properly referenced.

Unless your server is actually breaking (since you are shutting down) and not saving stuff to the database or something else weird is occurring, I personally would not worry about it until

Ugh! I want to help you more, so badly, but I am unable to. I was never able to get MaNGOS to compile even under *NIX. Sorry.

[kupix]

changing 1 to 30 with exit code 0 didn't help. same debug log.

i didn't mentioned, server was compiled in debug mode. maybe this is a reason. will check in a sec.

[wolverine]

I never thought about asking about that even. That could very well be the issue at hand. None of your log looked very consequential to me. Try recompiling with Release mode. And if that doesn't work, try 32-bit release. I know you have a 64-bit os, but perhaps something was overlooked in the source code...?

I have to use Visual Studio Express, so I can't compile 64-bit and as such have no clue if that could be part of the issue or not. Sorry. ???

[kupix]

just compiled as a "release". same shit here.

i'll check on 32bit machine tomorrow and post a reply
