Game frequently crashing - Error code 277

Help and Feedback Scripting Support
#1

My game is facing a problem where it crashes after 20-30 minutes, provided there is a high player count in the server.

I believe it could be attributed to the strong use of pathfinding service in the game, so I will paste the pathfinding script below. This pathfinding script is used to make the monsters chase after the player. However, because there are so many monsters, its likely that after time its causing the game to crash.

Any help is appreciated! Thanks!

Pathfinding script:

local myHuman = script.Parent:WaitForChild("Humanoid")
local myRoot = script.Parent:WaitForChild("HumanoidRootPart")
local head = script.Parent:WaitForChild("Head")
local lowerTorso = script.Parent:WaitForChild("LowerTorso")

local grab = script.Parent:WaitForChild("Grab")
local grabAnim = myHuman:LoadAnimation(grab)
grabAnim.Priority = Enum.AnimationPriority.Action

local grabSound = head:WaitForChild("Attack")

local clone = script.Parent:Clone()

local gameSettings = require(game:GetService("ServerScriptService"):WaitForChild("Modules"):WaitForChild("GameSettings"))

local damageIdo = gameSettings["EnemyInfo"][script.Parent.Name]["Damage"]

function findPath(target)
	local path = game:GetService("PathfindingService"):CreatePath()
	path:ComputeAsync(myRoot.Position,target.Position)
	local waypoints = path:GetWaypoints()

	if path.Status == Enum.PathStatus.Success then
		for i, waypoint in ipairs(waypoints) do
			myHuman:MoveTo(waypoint.Position)

			if (myRoot.Position - target.Position).magnitude < 6 then
				-- stop moving if within 10 studs of target
				attack(target)
				break
			end
			if (myRoot.Position - waypoints[1].Position).magnitude > 20 then

				findPath(target)
				break
			end
		end
	end
end

function attack(target)
	if (myRoot.Position - target.Position).magnitude < 5 then
		grabAnim:Play()
		grabSound:Play()
		if target.Parent ~= nil then
			target.Parent.Humanoid:TakeDamage(damageIdo)
		end
		wait(1)
	end
end

function findPlayer()
	for _, v in ipairs(game.Players:GetChildren()) do
		local plrPosition = v.Character.HumanoidRootPart.Position
		if (myRoot.Position - plrPosition).magnitude < 75 then
			return v.Character.HumanoidRootPart
		end
	end
end

function main()
	local target = findPlayer()
	if target then
		myHuman.WalkSpeed = 14.75
		findPath(target)
	end

	-- Add random jump behavior
	local jump_probability = 0.05 -- Adjust this value to change the frequency of jumps

	if math.random() < jump_probability then
		myHuman.Jump = true
	end
end

while wait(0.05) do
	main()
end

I found this article from another website saying:

If you’re experiencing error code 277 whilst playing Roblox, you almost certainly have a problem with your network. In other words, the internet or data connection to your computer, phone, or tablet is not working well enough to sustain a connection to Roblox.

Yeah, the thing is that when it crashes, it affects every single player in the server. If it were a network issue, wouldn’t it only disconnect the player experiencing the issue?

#4

What is the server memory usage before the crash when the game starts and after 15 minutes?

#5

How do you check server memory usage? Or do you mean client memory usage?

#6

Go to the logs in the F9 menu, click server and then MemoryServer.

#7

Wow I never knew that tab existed in the console. But now I think I may have found the problem, it cant be normal for a script to use 230MB of memory…?

#8

Sever memory usage started at around 500MB, now its 1000MB after around 10 minutes.

#9

Someone a while back had a similar issue, and it was because the pathfinding was done very far from the origin of the world (0,0,0).

#10

Well the pathfinding is taking place max 100 studs from the origin.

However after looking at the memory usage, the pathfinding scripts are not using much memory.

Compared to game handler using 500MB, and increasing significantly.

It’s probably not the pathfinding scripts, but whatever the GameHandler is doing.

#13

Yeah seems that way. I’ll paste the game handler script, as I’m not exactly sure what could be causing the huge memory usage. Although it might be to do with the coroutines being used.

I was thinking of that. It seems like you’re using coroutine.wrap, which can be changed to task.spawn. It might also be possible that you’re not clearing one of the many tables involved in the game thread.

#15

I’ve never used task.spawn before, but ill give it a shot.

#16

Solution was to modify the game handler so that the “checkForDeadHumanoid” coroutine didn’t execute so many times, and to yield it once it was no longer required.
