Strange Crash

KingMort · #1 01-03-2010, 10:37 PM

Not sure wtf this means but this is pretty much the only crash I get... Was hoping some one could help me figure out how to fix this.

Code:

Core was generated by `./zone'.

I get that crash occasionally as well. I think it has something to do with a certain scenario when it is doing the CheckWillAggro check. I don't really know how to read those very well and didn't see any problems that stood out in the code for it, but I do get it too.

KingMort · #3 01-04-2010, 03:59 PM

On my end it's like a plague , hits at least once every couple of hours..

**gaeorn** · #4 01-04-2010, 07:31 PM

this part

Code:

#0  0x0000000000000000 in ?? ()

shows it can not identify the function it was in. this often times means memory corruption, if it indeed in memory corruption, it is possible the backtrace is completely incorrect. this kind of problem can be very hard to track down.

make sure you have all the zone files in the map dir under eqemu..
it's telling mobs can't argo you because you are missing files
under the map dir or other files in your eq dir to go with the zone
your in. that should solve this problem.

Memory corruption has no relation to .map files. Trust me on this, if it's truely memory corruption, then it's going to be a completely different issue than what the coredump is getting at, most of the time.

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...

Code:

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

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

Code:

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

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

Code:

  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** · #10 01-15-2010, 06:09 PM

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

KingMort · #11 01-15-2010, 11:50 PM

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

**gaeorn** · #12 01-16-2010, 02:33 AM

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.

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

**AndMetal** · #14 01-16-2010, 03:31 AM

What's up with the nulls in the characters' names?

Code:

(gdb) print iOther->name
$3 = "Harry\000e", '\0' <repeats 56 times>

Code:

(gdb) print iOther->name
$3 = "Sand\000me", '\0' <repeats 56 times>
