Crash Offsets

TEST is an AND that discards the result. ANDing something with itself yields itself, but affects the flags. It is commonly used as a short way to test for zero, but it can also test for negative numbers, when the high bit is set. So test reg,reg preserves reg, clears the carry flag and sets the zero and sign flags accordingly.

Reading old paper tutorials, but without good reference hard to understand…

What assembler reference you will recommend?

I use these two:
Intel Architecture Software Developer’s Manual - google it, 3 pdfs.
http://faydoc.tripod.com/cpu/

oh, there’s actually third in my bookmarks: http://ref.x86asm.net/

Thx again, server much stable x)

server.dll, 0076fdf

?get_behavior_id@IObjInspectImpl@@UBEHXZ

Wrong behaviour? Right?

Um, yeah. That address is part of a function at 06D56FD0 (ie. server.dll has a base address of 0x6CE0000, add 0x76FDF and backtrack). Tracing it through the disassembly, it seems to be used when loading a player.

So perhaps it’s a corrupt character? Non-latinic name or something?

It seemed we have corrected all errors, but now happens only

ntdll.dll, 00011689

Os error?

Debug shows

[23.07.2010 12:12:53] void __stdcall HkIServerImpl::BaseEnter(unsigned int,unsigned int)
[23.07.2010 12:12:53] iBaseID: 2805853963
[23.07.2010 12:12:53] iClientID: 4

I have a problem to get more information ;(
I have a crash at 0x0004f486 in common.dll that appears very often. With a dll viewer the address should be somewhere between:

protected: virtual __thiscall CObject::~CObject(void) 0x062af440 0x0004f440 565 (0x235) Common.dll D:\Games\Freelancer\EXE\Common.dll Exported Function

and

public: unsigned int __thiscall CObject::AddRef(void) 0x062af600 0x0004f600 1197 (0x4ad) Common.dll D:\Games\Freelancer\EXE\Common.dll Exported Function

Am i on the right was assuming that it must be somewhere either in destroying an object or adding a reference (whatever ref is meant with it)? Because that are the addresses situated next to the crash offset.

Is there a way to get to the direct address that is crashing? Windbg? Any other tool?

Related to ntdll.dll - not supported/equipable archetype in players char file.

Use Player Cleaner or DSAccount manager with all check options on.

@Huor: At least in XP, the crash report itself should give you the address. Here’s one I prepared earlier… But you’ve got the right address, anyway, it’s part of the destructor.

Is there any possibility to get a kind of callstack of a current happended crash? It would be nice if its logged somewhere in a file… I have tried to debug a crash offset (by using breakpoints) but the routine is way too much called to trigger any crash reason ;(

So actually when the crash happens and having the callstack would be a really great…

Finally ntdll.dll crashes - Not supported parameter or typing error

@Huor try WinAPIOverride32

00091f38 in common.dll

because ship_archetype = <blank>in players file</blank>

is there something wrong with the engbase.dll. I dont see anything in depends and another dll viewer is also empty

i just could figure out the crash offset in windebug - but there is one little question i have. The offset that is given is that the offset from the module load entry or from the start of freelancer.exe? For sure both result in another address ;D
It seems there are no further information about engbase.dll at least all i could retrieve is assambler code - and my understanding of it is heavily lacking ;(

Whats wrong with engbase.dll? - I do not remember, remind please

constantly getting crashes, almost on a 10-20 minute schedule in dalib.dll

dalib.dll v. 1.0.1254.11 at 00004353

What happens usually is the server is running fine and all of a sudden all players experience red lag. As I watch console view I see usually 3 hits in a row, Sat Jul 31 17:18:35 2010
.\HookFunctions.cpp(887) : *** ERROR: Exception in Hook_IServerImpl_TradeResponse (unhandled exception)
and then all internet players get booted. Usually FLServer also crashes generating the dalib.dll error in the event viewer.

Here’s what I’ve done so far.
Replaced EVERYTHING between the monitor that I look at and the utility pole outside.

ISP ran new cable to the house, new modem, new account, I replaced the router and the server machine, reinstalled Windows XP several times (latest install WinXPsp3 with no updates), reinstalled all software, (FL, FLAC) and the problem persists. This is while running the mod or not running the mod.

Also, (I’ll start another thread on this) I’m wondering if it might be server list related. A couple times I’ve noticed that FLServer has lost connection to the list server and reacquired it. On at least one or more occasions, the crash happened at that time.

One more thing…
If I use Crazy’s List Server mod my server will show up on the list and on the server activity graph at flserver.de.
If I use w0dk4’s gls server workaround patch (v1.0), no connection to the list server. I can get on being on the LAN, but nobody outside the LAN can get on.

I’ll have to contact w0dk4 for more info on that.

@robocop: That’s due to a memory allocation failure (in CDPMsgList::Add, if that helps anybody). It’s only asking for 12 bytes, so there must be some serious memory leakage going on.

@Huor: Engbase is accessed by virtual functions (retrieved by DACOM_Acquire), which is why there’s nothing exported.

@adoxa
I wondered about memory leakage…
The ONLY thing this machine is running is WinXPsp3 (no updates past sp3), FLServer, and FLAC.

All unnecessary services have been disabled.
This started about a year ago out of the blue. No known cause. I thought it might be hardware related and ran the server on a different machine. Same problems. I replaced the server with a completely different setup again, same results.

It’s independent of the mod and FLAC hasn’t been changed or updated since well before the problems began.

So, is it possible that somebody is doing something malicious via the FL port(s) that might be causing this?

A server reboot usually forestalls the problem for a couple hours before it begins again so you may be on the right track with memory leaks.

What can I do to get rid of this problem? I don’t have much more hair to pull out.

@robocop:

I have just realised that I might I have the same problem on a test server. Every 20 minutes or so the server freezes and is restarted. Sometimes a OS reboot seems to fix the problem for a random period of time - sometimes days.

When the server freezes, the flhook console is locked up but the FLServer uptime counter continues to count up.

The server is running in a VM and I thought it might have been related to the VM software. The OS is XP 32bit SP3, a clean install.

When did you install SP3 - a year ago?

The mod definitely works okay on my XP machine. I’m sure it is not the mod. It could be flhook stuff but I am/was running production plugins.

I threw windbg at it and I think it was freezing when it was trying to execute level0? ring code but I really have no idea what I’m talking about.

If anybody wants to debug it for me, remote access is available…

Also, (I’ll start another thread on this) I’m wondering if it might be server list related. A couple times I’ve noticed that FLServer has lost connection to the list server and reacquired it. On at least one or more occasions, the crash happened at that time.

I wondered the same thing but I removed all list server stuff and it didn’t seem to help.

Well…, welcome to the club. I was starting to think everyone was looking at me sideways on this issue…

This has been going on for over a year now. The current install is only a week old. WinXPsp3 with no other updates.

Perhaps I’ll try running WinXPsp2 to see if the problem goes away but I’m pretty sure the problem existed well after upgrading to service pack 3.

Watch your event viewer. Application section should show any FLServer crashes. In there you should see which module is affecting flserver.
