Massive memory leak when exiting minecraft while using forge

[Zimosis]

I am getting a massive memory leak when I exit minecraft while using forge. This happens with or without any mods actualy loaded.

I have tried it with both 1.7.10-10.13.4.1448-1.7.10 and 1.8-11.14.3.1450 with the same result.

 

fml log 1.7.10-10.13.4.1448-1.7.10: http://pastebin.com/32MsKkKq

 

fml lg 1.8-11.14.3.1450: http://pastebin.com/92u8WZ1Q

 

Edit: Forgot to mention. Ive done a search for a solution to this but my search has not bine fruitful.

Edit 2: I can run minecraft by itself without forge without any problems.

By massive memory leak I mean that the memory usage of java rises to 1.5+ gig when I shut down the game.

[LexManos]

And then the JVM dies because the process ends and all memory is freed.

There are a few things that would eat memory while shutting down, mainly saving the world.

But once the JVM is dead, the JVM is dead.

If you're saying the JVM DOESN'T DIE then that is a issue.

You should try and grab us a profile snapshot using jprofiler {it's in the JDK bin folder, or just google it}

However just randomly saying 'MASSIVE MEMORY LEAK' with no further details besides logs spanning two differnt mc version {and thus impossible to tell the differences} that don't show ANY issues is not helpful.

[Zimosis]

The JVM does not die.

[LexManos]

Then something you have installed is keeping the jvm alive. Be it a poorly configured JVM, and antivirus, a mod, or something of the sort. However Forge should not be the cause of this as we'd of seen it on millions of other users.

As it sounds like you have no idea what you're doing, I'll ask you this. Do you know what teamviewer is, and if so would you be willing to let me remote control your computer so that you can show me this and we can do some debugging. I highly doubt it's forge but there is nothing we can do without ACTUAL data.

[Zimosis]

Here are two snapshots from jprofiler

[Zimosis]

Its not a universal problem. It only happens when I use minecraft with forge not just minecraft or any other java program.

[LexManos]

Those snapshots show the memory allocation and the jvm termination. But you haven't recorded the thread stack states or anything like that.

There shouldn't be any reason for your JVM to not terminate.

If you're willing i'd like to try and actively debug this on your computer through teamviewer.

It's been 'reported' a handful of times before but nobody is willing to help debug it so I chalk it up to something broken on their end because we have millions of users not reporting anything.

[Zimosis]

I have installed teamviewer If you would like to take a look for your self.

Start a session and e-mail me the details at [email protected] and i'll connect

 

[Edit]

Alright did some debugging with him, seems as if it's a driver issue {his graphics card/drivers is ~4 years old -.-} and the new loading screen.

However the issue is NOT happening inside of Minecraft AT ALL. it's completely exiting the MC codebase and EVERYTHING java related and stalling in native code after everything else is terminated.

Below is his log and driver info so I can pass it along to fry when he gets back.

For now the solution is to disable the loading screen and hope nothing pokes the launcher to be stupid.
