release The Hidden Killer of Game Sources: Memory Leaks and RAM Optimization via Valgrind

[Black_Rose©]

I won't beat around the bush—those who have dealt with server crashes or unexplained lag already know exactly how frustrating this issue is. Please remember to adjust the values and configurations provided in this guide to fit your specific environment.

Today, we are diving into a topic that hasn't been covered in depth on this forum but is absolutely vital for any large-scale project (1000+ players): Detecting Memory Leaks.

Many server owners complain about sudden lag or notice that their RAM fills up completely after three days, forcing a reboot. The primary culprit is usually poorly implemented new and malloc commands in custom systems that were never properly closed or deleted. This guide will show you how to pinpoint these leaks with surgical precision.

🛠 Step 1: Installing Valgrind

To begin, you need to install Valgrind on your server via Putty. Use the command corresponding to your operating system:

For FreeBSD:

Bash

pkg install -y valgrind

For Ubuntu or Debian:

Bash

sudo apt-get update && sudo apt-get install valgrind -y

---

🚀 Step 2: Launching Game Core Analysis

Typically, you start your game using ./sh start.sh or ./game. To catch leaks, we must run the game through Valgrind instead. Navigate to your game directory and execute the following command:

Bash

valgrind --leak-check=full --show-leak-kinds=all --log-file=leak_report.txt ./game

NOTE: Because Valgrind monitors every memory movement in real-time, the game will run significantly slower in this mode. This is strictly for testing. Once you find and fix the leaks, you can return to starting the game normally.

---

📊 Step 3: Pointer Comparison Table (Best Practices)

To prevent leaks from happening in the first place, we should move away from old habits and adopt modern C++ methods:

Feature	Classic Pointer (Raw)	Modern Pointer (Smart)
Syntax	CHARACTER* ch = new CHARACTER;	auto ch = std::make_unique<CHARACTER>();
Deletion	Requires manual delete ch;.	Automatically deleted.
Leak Risk	❌ Extremely High	✅ Zero

---

🔍 Step 4: Analyzing the Report (leak_report.txt)

After running the command for a while (log into the game, walk around, and trigger some systems), download the leak_report.txt file created in your directory via WinSCP. If you see an error like the one below, you've successfully found a leak:

Plaintext

40 bytes in 1 blocks are definitely lost
at 0x4C29F73: malloc (vgpreload_memcheck.so)
by 0x401087: CreateNewItem (item_manager.cpp:150)

What does this report tell us?

• "definitely lost": This confirms a definitive memory leak exists.

• "item_manager.cpp:150": Memory was allocated on line 150 but was never freed or deleted.

---

✅ Conclusion and Recommendations

• Every time you add a new system, make sure to run a 10–15 minute test with Valgrind.

• If you are still using the old-school new method, ensure you handle the delete operation within the destructor.

• If you want your server to remain stable for weeks without needing a reboot, this optimization is mandatory.
