you ran out of memory

VladimirMangos · May 24, 2010

maybe not, but provided data not show problem: 2 cases when Object::GetUInt32Value use in Unit::DealDamage safe from like crash (it must crash early in code if any problem).

Possible you have custom code in function...

berylo · May 24, 2010

Yes i have some custom code and probaly it's the reason but maybe you could help me to notice which one. Last thing in mangosd.exe is something like "Dealdamage: victim just died". I Noticed that Baron Rivendare was the reason. He was fithing with mob and when it had died server crashed. I deleted him cuz its fun server and i dont need him. Server still crash but not as often as before. Again last thing in mangosd.exe is "Dealdamage: victim just died" but i can find which creature do it. Its nonsense to delete all creatures which are doing crashes. Maybe you can help me find what is the true reason.

VladimirMangos · May 24, 2010

then look GetUInt32Value calls in function code after this put and check that pointer used for GetUInt32Value call checked as existed before use...

if "DealDamageAttackStop" not output then someting from ypur line but before "DealDamageAttackStop"

as i say i not see possibility for this in mangos code. So maybe some custom added in this lines range.

You can find this by compare you code and code in mangos repo.

berylo · May 24, 2010

Can you tell me in which file should I look for it first? object?

VladimirMangos · May 24, 2010

??? discussed code in Unit.cpp

You ask strange question. Normal way is find "Dealdamage: victim just died" in code...

berylo · May 25, 2010

This is my Unit.cpp. I am now sure that PvP Token does crashes. When I deleted it everything was fine. I think it's at wrong place or maybe something is missing. Could u help me with fixing that, cuz i need that patch?

An this is PvP token in Unit.cpp which I am talking about:

// PvP Token
       int8 leveldiff = player_tap->getLevel() - pVictim->getLevel();

if((pVictim->GetTypeId() == TYPEID_PLAYER) && leveldiff < 10)
       player_tap->ReceiveToken();

       WorldPacket data(SMSG_PARTYKILLLOG, (8+8)); //send event PARTY_KILL
       data << uint64(player_tap->GetGUID()); //player with killing blow
       data << uint64(pVictim->GetGUID()); //victim
       if (Group *group = player_tap->GetGroup())
           group->BroadcastPacket(&data, group->GetMemberGroup(player_tap->GetGUID

()));
       else
           player_tap->SendDirectMessage(&data);

lecails · May 25, 2010

       WorldPacket data(SMSG_PARTYKILLLOG, (8+8)); //send event PARTY_KILL
       data << uint64(player_tap->GetGUID()); //player with killing blow
       data << uint64(pVictim->GetGUID()); //victim

SMSG_PARTYKILLLOG ? What is this Opcode ?

berylo · May 25, 2010

This is patch which i applied http://github.com/Darkrulerz/mangos/commit/37dd08307dd5914823e9a716b8d52206df3a8eab

I dont know if u think about that:

/*0x1F5*/ { "SMSG_PARTYKILLLOG",                            STATUS_NEVER,    &WorldSession::Handle_ServerSide               },

Thyros · May 25, 2010

yes berylo i have added this system and now crash the core very often, i have deleted this part, and now works without crash.

Darkruler · May 25, 2010

I will, it worked before [9918] so i didn't think it was broken...

give me a few hours, got some other things to do first

berylo · May 29, 2010

It crash again. This time its mangosscript.dll fault

Anyone know a reason?

http://paste2.org/p/856548

edit: I had no idea. I deleted 4 creatures mentioned though and now everything seems to be ok. Strange could be a fact that 2 of these NPCs was Thrall and King Varian

edit2: Something wrong is with that Vmap. It is a reason of the crash

Thyros · May 30, 2010

compile on debug and you see the lines what make this crash.

berylo · May 31, 2010

Finally, Thrall from Hyjal Summit was standing in orgrimmar. I deleted him and everything is fine now. Sorry for spam
