What can cause memory leakage?

[sheppard929 (Sheppowd)]

Hello everyone
i found a memory leak on the server & client side i think
what kind of problem can cause leaks ?
because as time goes by, on the server side the untracked memory increases (not very fast but still)
on the client side I haven’t determined the cause yet, but the Client memory also rises at the same speed than the server Untracked memory
thanks for answering

What kind of problem are you experiencing which makes you think you have a leak?

Please post in greater detail to help us answer you properly.

…? How many different questions is this?

• What can cause memory leakage
• Something about localisation, which I’m not sure how it’s relevant here
• You “found” a memory leak (not even sure?)
• What can cause memory leaks
• How to locate memory leaks

I think you’re going to need to revisit your post a little here. What you’re trying to ask is fairly obscure and I can’t discern what it is you’re trying to get from creating this thread. Please be sure to explain your situation in detail and read the Scripting Support Category guidelines for information on using this category.

Furthermore, I feel like your question is heading straight into XY Problem grounds. What is the actual issue you’re facing? Is it truly memory leaks, or is there another issue that’s largely at play here?

Yes, interestingly another thread reported out of control untracked memory here:

Untracked memory becoming major source of game's memory leak issue

I wish to lower memory leaks to the lowest possible amount. Starting a few days ago, untracked memory has become the largest percentage of total memory usage on the server. About 70% worth. This server was 5-6 hours old, so if the untracked memory was way less, it would be acceptable to be around 700-800mb. [image] I have taken several weeks worth of experimenting with the brilliant insight from this thread, to do the things that have been laid out. Now untracked is the worst problem. I…

This does not suggest a memory leak, and (FYI) it seems to be a roblox internal issue from what I’ve seen.

I’m going to modify the post ^^
the real questions is

I found a few articles that may help you to understand memory leaks better:

Memory Leak Issue

Hello developers and potentially staff, Long story short, I’m working on a game and after an hour or two, this begins to happen. The memory just slowly goes up until things get a little jumpy in the server and connection becomes more volatile; the server might even crash entirely. I was hoping one of you guys would have a solution to this, such as a way for me to track down exactly what is causing this leak/issue.

Dedicated article on what these are and what causes them:

PSA: Connections can memory leak Instances!

Preface I’ve seen several experienced developers not knowing this, or not having a full understanding of what’s going on, so I thought I’d write a dedicated post on the issue of accidentally leaking Instances (so that they are not GCed even when there are no references to them) through lingering event connections. What circumstances cause a leak do -- All good, this part will be GCed just fine local p = Instance.new('Part') p.Touched:connect(function() print("Touched") end) end do -- O…

These might help you understand a bit better.
