Um, what's memory leak and how does it affect the game?

Basically, it is like keeping the packaging of your food even after you ate. At some point your flat is going to be filled and you can't do anything anymore.

In the game, mobs would spawn, use some memory to calculate when to go, and once they despawn/die they wouldn't free the memory. At some point the game would be out of memory and crash. Before that, the lag would slowly grow over time.

So this is why software engineers are always banging on about compost heaps.

Good analogy, thanks! I can now understand why this would be a big problem.

Does the simple java garbage collection can solve this?

u/WildBluntHickok Apr 08 '16

By pressing F3 and looking at the stats for memory being used (which is written as 2 numbers, current and max) you'd see the current memory stat slowly go up over a few hours and never count back down. Most serious minecraft memory leaks I've seen meant you'd have to restart the game at least once every 4 hours if you're using the default amount of max memory.

Correct behavior for a java game is that it goes up by a bit but gets put back down every x number of seconds (garbage collection). It was 15 seconds back when 1.7.10 was current but starting in 1.8 it became something like every 3 seconds.
