Roblox internal memory leak causes my game servers to undiagnosably crash every 3 hours

[Maelstorm_1973]

I read several other threads that described a similar problem. The memory leak seems to have something to do with character models being cached but the cache is never purged. Someone suggested adding this code to the server to help fend off the memory leak:

local playerService = game:GetService("Players")

playerService.PlayerRemoving:Connect(function(player)
	if player.Character ~= nil then
		player.Character:Destroy()
	end
end)

That supposedly forces the engine to destroy the character and purges the character appearance from the cache. Several individuals have said that it helps.

I’ve tried this to no avail, unfortunately.

This bug report has been open for nearly two years - at this point I’ve just accepted my game can’t be fixed as this is totally undiagnosable and absolutely destroying my userbase and retention. I’m not sure what I can do to fix it anymore.

I reported this problem again, but with a different area of the leak, which also has a very big impact on performance.

Server network/raknet Memory Leak?

This is a problem inside my game, which actively uses remote events and remote functions, since this is a communication game, the server has a maximum of 110 players, but the server has too much memory in CoreMemory/network/raknet. 1 GB of memory, is this normal? If this is expected, are there better ways to use remote events and remote functions? This affects the performance and stability of servers. 12:42 timestamp: [image1] 16:20 timestamp: [image2] Expected behavior This memory area …

This issue is still open, I will keep an eye on it and share everything I have

Pretty sure around may the touch event broke on the client and that could somehow be related which is unlikely

Can confirm we are seeing this exact profile appear in our game too.

Experiencing this as well. Unfortunately no way to pin it down; would love any and all help!

Same here. It just keeps rising.

This error ended up being caused by our datastore system. We were using a folder heirarchy - when a player joined, we would clone the folder structure, fill it with values, and make it accessible to the client via replicatedstorage.

Don’t use this method. We removed it (switching to a table structure stored on the server, made accessible to clients via remotes), and the issues vanished.

Im sure its been a very long while since you even thought about this problem, but are there any other workarounds? My game uses the same system, and recoding the entire game to fix this issue would be a massive pain…
