Extreme lag spikes / too much memory usage

Sometimes (but not often) the game starts to have extreme lag spikes - several seconds of the same frame - and it seems to happen because the memory usage goes to 98% to 99% (maybe even 100% but I have not seen it), possibly because it cannot release unused memory resources fast enough.

Even the menu when the game is paused is extremely laggy (but not the main menu).

I'm playing with 2 GB of reserved memory (8 GB total) as set via the JVM arguments profile option ("-Xmx2G") and this has never happened to me before (even when I used to play with only 1 GB of memory).

Your OS as well as your Java are outdated. Update it.

This is a technical support issue; this site is for bug reports only. For technical support please use the Mojang Support Center.

@Kumasasa Can you point me to where it says that OS X 10.6.8 and Java 1.6.0_65 are outdated? According to this I meet the minimum requirements: https://help.mojang.com/customer/portal/articles/325948

Yes, didn't say that your specs don't meet the minimum specs, but I'm still saying that your OS & Java is outdated and I'm still saying that this lag is no bug.

Several seconds of a frozen screen followed by a few moving frames followed by several more seconds of a frozen screen, etc that never happened before 1.8.1 with the exact same setup doesn't sound like a bug to you?

This isn't lag your typical lag. I can film it for you if you want. It's definitely a bug.

Please attach the complete output of the "Game Output (Your Minecraft name) " which can be found on the fourth tab of the launcher.

If the launcher closes after game start, please edit your profile and select "Launcher visibility" then, "Keep the launcher open".

Attached the complete game output log.

I just died in my 2-year-old hardcore world because of this bug! A witch was attacking me and the game suddenly started freezing up for 2-3 seconds at a time, leaving me only half a second or so in between to do anything.

I tried to force a crash from the death screen (where it was still continuously freezing up like this) but that doesn't seem to work.

I don't have a backup of my world, but I made a copy of the world save folder after the death screen came up, and I'm trying to recover from this.

I just got back to playing Minecraft after a few months' break due to this upsetting event.

I'm disappointed to see that this problem has not been fixed yet.

How does Mojang expect people to play hardcore when the game cannot be trusted to not randomly kill you? Stability is paramount to this game mode.

Losing your two years old hardcore world because you died due to factors beyond your control is not cool.

Is this still an issue in the most recent versions (i.e. 1.10.2, or 16w42a) of Minecraft?
