Alright well this was the latest drop.. I took out all un-needed factions in the game and found a fairly large reduction in the crashes but still...

Caesar is a player, and so is Sand ...

[Derision]

This makes no sense to me. If we consider frame 3

#3  0x0000000000719042 in EntityList::CheckClientAggro (this=0xbdcfa0,
    around=0x7feab85bb4b0) at aggro.cpp:45

This is the code from aggro.cpp around that line:

  39         for(iterator.Reset(); iterator.MoreElements(); iterator.Advance()) {
  40                 _ZP(EntityList_CheckClientAggro_Loop);
  41                 Mob* mob = iterator.GetData();
  42                 if(mob->IsClient())     //also ensures that mob != around
  43                         continue;
  44
  45                 if(mob->CheckWillAggro(around)) {

So in your backtrace, mob->CheckWillAggro is called at line 45, but you are saying that both mobs involved are players, but line 42 checks if mob is a client and will skip line 45 and move on to the next mob if that is the case.

Strange.

I note that both the BTs you posted are for kerraridge. Do all the crashes happen there ?

Have you talked to the players involved in the crashes to see what they were doing at the time the zone crashed ?

[trevius]

Could this be due to players being charmed there by chance?

[KingMort]

No not always in Kerra Ridge it's just wherever and whenever.. Some times there some times in other zones...

I asked them what they were doing before the crash and they said nothing other than clicking on the other player.. And in all cases of this crash it seems it's players clicking on other players that cause the crash and never any NPC's involved..

Is there any more BT commands i could do to help you guys figure this one out ?? I'll do anything at this point lol

[KingMort]

Just an update, I replaced all my map files with the latest current stuff and it seems some of the crashing has cleared up thanks for that suggestion..

I have some NEW ones I guess (maybe not though could be still related) only difference here is that it seems like it's a mob now instead of a player..

At least that crash has a function name we can check into. I'll see if I can look into this in the next day or so.

[gaeorn]

Mort's code isn't pure emu, nor is it 100% up to date (although it's much more recent than it was a few months ago). So chances are there is some other code around line 45.

[KingMort]

My code is the same as anyones honestly other than a few very minor changes... always tried to do my own thing except recently i have found that my fellow artists and myself need to hopefully gain some type of community effort hehe ..

My database however is probably pretty old school or something..

Gaeorn are you not on IRC anymore I think i have a solution for all of this if you just will contact me please

I'm on all day during weekdays. Just need to look me up by name if you don't see me in a particular channel.

Alot of servers I've played on mobs will assist charmed pets. Just throwing that out there....randomly probably
