Disconnect bug

[Spiker]

So, this has been happening to Graal Kingdoms for a loooong time now, and I think it's time to start a thread and get the players of GK to explain what they have noticed causes it so it can be looked at with evidence instead of nothing being done about it; Information is better than nothing even if we can't fix it. I feel this bug is the reason why GK is dead most of the day when the bug is active, and it needs to be fixed pronto if we want any sort of player base.

Disconnect bug happens when you:

• Open a container with items in it (Doesn't always happen)
• Walk into a certain level (Not much known about this one)
• Grabbing an Anvil or anything that seems to get information from the database (Does not always disconnect, only randomly)
• A server restart does not seem to fix it or cause the issue
• Double clicking a stack of rum causes me to disconnect SOMETIMES (~7,000 Rum)
• Does not effect Mac at the same time as Windows, or does not disconnect for the same reason

Please post what you have noticed causes the disconnect when the bug is active.

Disconnects from just running around main (Coordinates are recorded after logging back in):

main_ak-16.nw x: 54 y: 55.5
main_ak-11.nw x: 33 y: 57.5

Yeah, it is getting really annoying. I've only really had it though when walking around the main gmap, using an anvil and sometimes when in a dungeon.

Please be more specific.

Not too sure how, It seems to occur pretty randomly to me. I walked from Bomboria trade to the Christmas dungeon and got disconnected 5 times, another player was following me there and didn't get disconnected once. Once inside the dungeon I got disconnected after casting a few spells.

I logged in accepted the daily things, it disconnected me.
The one with the sack, it seems happens if there's a lot of items, it didn't happen when the sack was empty or had few items.

This error is also specific to Kingdoms, as I can log on to my own server when lots of disconnects are happening without being affected at all.

[scriptless]

I have been having internet problems disconnecting me a lot lately but for me its all been my internet. Now that GK is doing it thats going to kill me ... well at least some of my internet problems will be over soon.

[CharZAK]

there is not much to say for me...
i have d/ced a lot while trying to walk home on dustari
i have d/ced few from logging in
and so far only one time have i been d/ced for opening a rabbit sack

I get disconnected during accepting daily items also.

With the sack, I can actually open my endless sack with over 1,000 seperate items in it perfect, but opening my quiver with ~10 arrows in 1 stack disconnects me, so I don't think it has to do with the items in the sack.

EDIT: Everybody was just disconnected at 00:00 server time.

[shrimps]

lol I opened a pouch with diamonds + rubies and nothing happened.
I open a rucksack with all my misc items it dcs me 100% of the time.

nico did an npc restart yesterday i believe. dunno if that had anything to do with it.

how does this problem usually get fixed? just stops after a while?

Yeah, usually.

An NPC Server restart should not be the cause, though. I can't think of any cases on any server where it has made things worse.

The NPC restarts do not effect it. We thought they did at first, but after extensive testing, it does not help or harm the issue.

There hasn't been a fix for this issue yet, it just goes away after awhile.

Currently it's crippling our player count and needs to be fixed. :X

[HarlemBalla]

dunno if this helpful information but i was doing some testing on the gmap and every time i seem to be getting disconnected at the exact moment i cross over in to another level on the gmap. although, it does not happen every time you cross in to a new level.

I was testing this too and it doesn't seem to happen when you cross over into a new level. I have some coordinates in my first post from where I would get disconnected and none of those numbers equal a level change. Keep researching though! We will get to the bottom of this, since it seems like nobody else is.

[HarlemBalla]

if you look at your coordinates, they are somewhat close to the edge of a level (within 10 tiles). i started looking at my coordinates and was getting similar results. when you have a character with high speed you can travel 10 tiles like nothing. so i stripped my character of its gear to get down to 1 speed and found pretty consistent results:

main_ad-18.nw
46, 3.5

main_ad-20.nw
3, 27

main_ae-20.nw
1.5, 38.5

main_ad-11.nw
5.5, 60.5

main_aj-06.nw
2.5, 2.5

people have been noticing getting disconnected in dungeons which are GMAPs as well. i have not tested inside any dungeons and will not do that tonight.

if the problem is with GMAPs that would make sense why we are able to idle inside trade without problem.

hope this helps.

i also noticed that i was not getting disconnected from entering or leaving the same level twice.

I actually just did some extensive testing with this, and it does the exact same thing with me, so I understand how it can be with the GMAP. I have gotten some disconnects in the Xmas Dungeon, but I'm not sure if that's a GMAP also, if it is, this confirms our suspicion.

Also, I have noticed that if I am able to get my endless sack open, because it has so many items inside of it, that when trying to open another sack that is readied with the endless sack open, it lags my client for a split second and, for some reason, opens the other sack that never opens before.

[HarlemBalla]

the xmas dungeon levels are small GMAPs. i noticed the problem with GMAPs because i've done a bit of work with levels. i have no idea how the other incidents such as the anvils and the opening bags relates to the GMAP issue, seems very odd.

We locked the Server for debugging this issue.

We will keep you informed about the situation.

Hello,

unixmad logged on GK and fixed the issue.
GK is back up again.

This issue is happening once again. Please look into it...once again.

[xXTaikunXx]

I just wanted to tell you that this doesn't happen on macOS + mac client. It seems to be a windows-client problem. At least it worked on mac for me while windows dc me when opening a bag for example.

[NicoX]

Sorry for this issue.

We still do not know where the issue is coming from. Server is back to normal for now. We will continue looking into the issue though.

See you on GK.

by 'disconnect' does this mean it is sending players to the login server with the text "you have been disconnected from the server", or is it crashing the client altogether?

Just disconnecting, no crash.

[Jakov_the_Jakovasaur]

this is entirely a guess but the one thing each cause seems to have in common is that they all involve serverside processing of events after data is synchronised from clientside. are there possibly a lot of blank/erroneous files within the npcs/ folder with levelname set to these gmaps?

ive encountered similar albeit less severe problems in the past which resulted from classes attempted to be joined by said blank/erroneous npcs listed in that folder

Folder is empty.

if the folder is empty it would mean that either gk has no active local npcs/putnpc2 objects (which seems unlikely), or gk is using the alternative storage method where they are placed within an npcs/ subfolder using the individual level name

[CharZAK]

disconnects still happen from time to time when walking...but i seem to be having that issue on UN too
