Linux tool to detect memory leak

Question

Are there any tools to detect memory leaks of running programs in Linux? I know of Valgrind, but it's mostly used to debug for memory leaks and not simply to detect memory leaks.

Thank you.

I'm not sure, but something I have observed on my Minecraft server is the ever going memory cache its taking. To counter against the cache taking all the memory I run these commands in cron every day....

Command

sudo sync
sudo echo 3 | sudo tee /proc/sys/vm/drop_caches

free_memory.sh

#!/bin/bash
echo -e "\033[36mMemory before\033[0m"
free -m
sudo sync
sudo echo 3 | sudo tee /proc/sys/vm/drop_caches
echo -e "\033[32mMemory after :)\033[0m"
free -m
