What is this suppose to mean?

After getting this error roblox studio completely crashes, which is well obviously quite bad. It doesn’t appear 100% of the time but it does appear. I think its due to this script:

local Folder =  workspace.Zombies
local Player  = game.Players.LocalPlayer
local Character = Player.Character or Player.CharacterAdded:Wait()

local params = RaycastParams.new()
params.FilterDescendantsInstances = {Folder,Character}

local pathfindingservice = game:GetService("PathfindingService")
local path:Path = pathfindingservice:CreatePath({
	AgentCanClimb =  true,
	AgentCanJump = true,
	Costs = {
		Border = 0
	}
})

local db = {}
local dmgdb = false

local function AutoJump(zombie)
	local HRP = zombie:FindFirstChild("HumanoidRootPart")
	if HRP then
		local origin = HRP.Position
		local dir = zombie.HumanoidRootPart.CFrame.LookVector
		local ray = workspace:Raycast(origin,dir,params)
		if ray then
			zombie.Humanoid.Jump = true
		end
	end
end

local function DirectMovement(zombie,pos)
	zombie.Humanoid:MoveTo(pos)
	AutoJump(zombie)
end

local function getzombie(obj)
	for i,v in pairs(obj:GetChildren()) do
		if v:FindFirstChild("Humanoid") then
			return v
		end
	end
	return nil
end

local stillsincetick = tick()

local function PathfindingMovement(zombie,pos)
	task.spawn(function()
		if not table.find(db,zombie) then
			table.insert(db,zombie)
			local waypoints
			local reachedConnection
			local blockedConnection
			local nextWaypointIndex
			local success, errorMessage = pcall(function()
				path:ComputeAsync(zombie.HumanoidRootPart.Position, pos)
			end)

			if success and path.Status == Enum.PathStatus.Success then
				-- Get the path waypoints
				waypoints = path:GetWaypoints()

				-- Detect if path becomes blocked
				blockedConnection = path.Blocked:Connect(function(blockedWaypointIndex)
					-- Check if the obstacle is further down the path
					if blockedWaypointIndex >= nextWaypointIndex then
						-- Stop detecting path blockage until path is re-computed
						blockedConnection:Disconnect()
						-- Call function to re-compute new path
						PathfindingMovement(pos)
					end
				end)

				-- Detect when movement to next waypoint is complete
				if not reachedConnection then
					reachedConnection = zombie.Humanoid.MoveToFinished:Connect(function(reached)
						if reached and nextWaypointIndex < #waypoints then
							-- Increase waypoint index and move to next waypoint
							nextWaypointIndex += 1
							if waypoints[nextWaypointIndex] then
								zombie.Humanoid:MoveTo(waypoints[nextWaypointIndex].Position)
							end
						else
							reachedConnection:Disconnect()
							blockedConnection:Disconnect()
						end
					end)
				end

				nextWaypointIndex = 2
				if waypoints[nextWaypointIndex] then
					zombie.Humanoid:MoveTo(waypoints[nextWaypointIndex].Position)
				end
			else
				PathfindingMovement(zombie,pos)
			end
			table.remove(db,table.find(db,zombie))
		end
	end)
end

local function Update()
	for i,v in pairs(Folder:GetChildren()) do
		if v and v:IsA("Vector3Value") then
			local owner = v:FindFirstChild("Owner")
			if owner then
				if owner.Value == Player then
					local zombie = getzombie(v)
					
					if zombie then
						local zombiehrp = zombie:FindFirstChild("HumanoidRootPart")
						local zombiehum = zombie:FindFirstChild("Humanoid")
						if zombiehrp and zombiehum then
							if zombiehum.Health > 0 then
								local origin = zombiehrp.Position
								local direction = CFrame.new(origin,v.Value).LookVector*(origin-v.Value).Magnitude
								local ray = workspace:Raycast(origin,direction,params)
								if ray then
									PathfindingMovement(zombie,v.Value)
								else
									if tick()-stillsincetick > 2 then
										PathfindingMovement(zombie,v.Value)
									else
										DirectMovement(zombie,v.Value)
									end
								end
								
								if zombiehrp.Velocity.Magnitude > 1 then
									stillsincetick = tick()
								end
								
								local damage = zombie:FindFirstChild("Damage")
								damage = damage and damage.Value or 20

								for i,v in pairs(game.Players:GetPlayers()) do
									if v:DistanceFromCharacter(origin) < 7 and not v.Revive.Value then
										if not dmgdb then
											dmgdb = true
											game.ReplicatedStorage.RemoteEvents.DamagePlayer:FireServer(v,damage)
											task.wait(1.5)
											dmgdb = false
										end
									end
								end
							end

						end

					end
				end
			end
			
		end
	end
end

game:GetService("RunService").RenderStepped:Connect(function()
	Update()
end)

This script is a local script in StarterCharacterScripts. It handles zombie movement in my game. I have this because of optimization purposes.

Any idea on how to not get the error?

Hello, this error is typically caused when recursive functions call each other indefinitely, forming an infinite loop, causing an overflow. Here’s an example:

function test()
  test()
end
test()

Though this is pretty obvious, it is very possible that there is a logic error in your code somewhere causing this infinite loop under conditions, or there being too many function calls building up over time due to memory leaks. I haven’t been able to analyze your code, so I just wanted to provide some pointers. Hope this helps!

Hm, I see perhaps I can try replacing the PathfinddingMovement() function hereL

				nextWaypointIndex = 2
				if waypoints[nextWaypointIndex] then
					zombie.Humanoid:MoveTo(waypoints[nextWaypointIndex].Position)
				end
			else
				PathfindingMovement(zombie,pos)
			end

with DirectMovement?
Maybe that would help.

I’ll let you know in a while.

Issue solved! Turns out I forgot to add the “Zombie” parameter when I was calling it again in the pathfindingmovement function! Ha! So silly…

Anyways thank you so much @BuilderDolphin for the immediete response! I was not expecting this! Thanks again.
