Can a situation occur in Go where resources are not released, leading to leaks?

Memory leaks in Go are possible, even though the language has a built-in garbage collector that automatically frees unused memory. However, leaks can occur if the program continues to hold references to objects that are no longer needed, for example:

• Global variables or slices to which elements are added but not removed.
• Channels that are not closed and continue to hold data.
• Closures that capture large structures and are not released.

Thus, leaks in Go are more often related to program logic that prevents the garbage collector from freeing objects, rather than low-level memory management errors.

Example:

var cache = make(map[string]*Data)

func addToCache(key string, data *Data) {
    cache[key] = data // If cache is not cleared, data will be retained in memory
}

If cache is not cleared, objects in it will not be released, leading to increased memory consumption.
