[Solved] Multigame in one Server Error

Hi all
I face an annoy problem when run 4 game projects in 1 server.
Let call them A in port 2000, B in port 2500, C in port 3000, D in port 3500.
Player will join A as a Lobby for friend list and announcements, profiles ...
Then player choose Game B, client will connect to Game B when Game A still connect. Everything fine here.
But when leave Game B and connect to Game C (already have big room for everyone), Game C send error "room id already full" but just one player connect to this room.
I try Create game C, its still work. But join or joinOrCreate or joinById meet the same error.

here is the onCreate config:

    this.setState(new State());
    this.maxClients = 1024;
    this.autoDispose = false;
    this.setSeatReservationTime(60); 

I cant debug because this error from Socket library and I surely can't understand any code in that.
Please help me, any suggest can save my project here.

Update:

3 room A, B, C here. A create first, then B and the last is C.
but when I try to join C, socket client throw error room B is full ...

0_1604942675563_77b4e0f7-dd99-4648-9175-a3fefb9fe3e2-image.png

if I reset all socket and join room B, everything fine

Solve:
I copy index.ts from B to C, so they have the same Room Name like this:
0_1604968937047_0897ab6a-a504-4590-915b-602e343ee433-image.png

and when I declare Room Name difference, the error fly away.
Oh my :(

Hi @kai_nguyenhuu, the problem here is because MongooseDriver is being used using the same database for matchmaking.

If you specify a different database, each game should have its own matchmaking queues:

// for game 1
new MongooseDriver("mongodb://127.0.0.1:27017/game1")

// for game 2
new MongooseDriver("mongodb://127.0.0.1:27017/game2")

// ...

Hope this helps! Let me know if that works for you. Cheers!

Thanks endel
But I need ro use same db for every game :D
