Re: [Flashcoders] [MEMORY LEAK]
Just out of interest - why are you recreating the Loader() and
re-adding the listeners each time? It should work if you just create
the Loader once, add the listeners once - then every time you call
load() with a new URLRequest, you'll get new progress and complete
events.
Might help with your leaks.

Hello, this issue is killing me. I had a swf that loaded an xml file

I refresh that page memory use drops back to normal. So, I said screw
this, I'm going to create an empty swf and load the swf with all the
magic in it and add it to the empty swf. I figured if I add the swf to
the main stage and kill that one reference to the swf when I was done

Re: [Flashcoders] [MEMORY LEAK]
Every time it reloads
however, I watch firefox take away memory consistently and when I refresh
that page memory use drops back to normal.
First and most important, are you sure it's leak? The fact that Firefox (not
even the player itself) doesn't release memory right away doesn't mean
there's a leak. At all.
Sorry for the self reference, but a while ago I answered a question in
stackoverflow about an alleged memory leak.
http://stackoverflow.com/questions/1020146/why-sytem-totalmemory-keeps-increasing/1022648#1022648.
Perhaps it helps to get my point across.
Looking at Qindows manager or System.totalMemory is probably the worst
possible way to detect a leak, given how the player works. You'll get tons
of false positives and the info is rather useless anyway.
What has been of great help, at least for me, is using Flex Builder's
profiler. It lets you inspect objects in memory, force a gc, etc. Plus, if
you do find a leak, you can trace where the leaked object has been
allocated. A simple test for your scenario would be taking a snapshot before
loading your swf, then another when it's loaded, then unload, force a GC and
take another snapshot. Then you can compare memory at those points and be in
a better position to determine if there's a leak, and, in that case, what
could be causing it.
Hope it helps.

Re: [Flashcoders] [MEMORY LEAK]
Problem might be with the XML class. I've seen problems in Flash Lite 3 where
the idMap property of the XML class had to be deleted to prevent a memory leak.
Tracing idMap will say undefined, must use ObjectDumper to see what it's
actually pointing at. It appears that it will leak only if the XML file has
nodes with an attribute of id.

Re: [Flashcoders] [MEMORY LEAK]
I see. But when you refresh the page, the Flash Player instance is tore
down, so the player's memory is released. When you reload a stub swf, the
memory used by the player might or might not be released immediately. Most
likely it won't. That's not necessarily a bug or a leak. It could be, but my
point was that you should keep in mind that GC is not deterministic; because
maybe you don't have a leak in the first place. The mere fact that the
memory footprint grows doesn't mean there's a leak.

First and most important, are you sure it's leak? The fact that Firefox
(not

there's a leak. At all.

Looking at Qindows manager or System.totalMemory is probably the worst
possible way to detect a leak, given how the player works. You'll get tons

What has been of great help, at least for me, is using Flex Builder's
profiler. It lets you inspect objects in memory, force a gc, etc. Plus, if
you do find a leak, you can trace where the leaked object has been
allocated. A simple test for your scenario would be taking a snapshot
before
loading your swf, then another when it's loaded, then unload, force a GC
and
take another snapshot. Then you can compare memory at those points and be
in
a better position to determine if there's a leak, and, in that case, what

Hello, this issue is killing me. I had a swf that loaded an xml file then
loaded images from the xml file and then killed the display list, xml,
images etc... then restarted based on a timer. Every time it reloads
however, I watch firefox take away memory consistently and when I refresh
that page memory use drops back to normal. So, I said screw this, I'm
going
to create an empty swf and load the swf with all the magic in it and add
it
to the empty swf. I figured if I add the swf to the main stage and kill
that
one reference to the swf when I was done with it, I should have fixed my
problem. Here's my code. Can someone please tell me what is going on?

I see. But when you refresh the page, the Flash Player instance is tore
down, so the player's memory is released. When you reload a stub swf, the
memory used by the player might or might not be released immediately. Most
likely it won't. That's not necessarily a bug or a leak. It could be, but my
point was that you should keep in mind that GC is not deterministic; because
maybe you don't have a leak in the first place. The mere fact that the
memory footprint grows doesn't mean there's a leak.

Well I'm going to use gskinner's workaround by pulling the content swf
from
a subdomain. I am not looking at task manager overall sys memory but, at
the
privat working set from the processes tab. And I can see it get loaded
then
every refresh it adds 2-4MB to the working set. On page refresh it drops
back to where it was.

Re: [Flashcoders] [MEMORY LEAK]
TS,
what is the content that you are loading from this external swf every 30,000
milliseconds? It is feasible that what you are loading is causing the
memory of the Flash player to increase?
I never saw where you ready the swf itself for garbage collection. I see
that you are setting the loader to null but you still have the content on
the stage. Although it looks like you are trying to remove something from
the display list at position 0.
Are you sure that you are removing what you are intending to remove? Maybe
a more thorough emptying of the display list is in order such as a for loop
through the list, removing whatever might be on it.
And keep in mind that the garbage collection doesn't necc happen as soon as
you make something = null. It happens on a garbage cycle when Flash feels
like it, not when u want it to.
In Flash Player 9, the garbage collector's operations are deferred. This is
a very important thing to understand. Your objects will not be removed
immediately when all active references are deleted. Rather, they will be
removed at some indeterminate time in the future (from a developer
standpoint). The garbage collector uses a set of heuristics that look at the
RAM allocation and the size of the memory stack, among other things, to
determine when to run.

I have 2 swfs.
1) Loader SWF: no assets are on stage nor are they loaded into other than
the content swf. The code is a timer and a loader. The timer reloads the
loader every 30 seconds which pulls in the content swf. And yes the remove
something from the display list at position 0. is the content swf which
does disappear when removed from the display list. When I check for
numChildren there is indeed only one item in the display list which is then
removed.
2) Content swf: loads an xml file with 10 references to thumbnails, then
after finished it loads the thumbs into a carousel.
The timer essentially kills the content swf and reloads it. The purpose of
the entire app is to show thumbnails of videos currently being watched and
refreshes every 30 seconds.
Is it possible that the content swf is loading something that is running as
a global var or something which keeps it in the loader swf?

Re: [Flashcoders] [MEMORY LEAK]
All I can say is that you aren't releasing all of the references to this
material that you are trying to release from memory.
So after you make this call
addChild(loadEvent.currentTarget.content);
make that = to null as well as any other time that you are referring to this
content you are trying to rid.
I know if you run your program in Flex Builder and choose the profiler, you
can actually purge the garbage manually and see if the object you want to be
deleted gets purged. If it hasn't then there is still something that is
referencing it. However, after looking at your code it seems that you are
writing it on the timeline and i'm not sure how you would go about putting
that into Flex Builder.
best of luck

TS,
what is the content that you are loading from this external swf every
30,000
milliseconds? It is feasible that what you are loading is causing the
memory of the Flash player to increase?
I never saw where you ready the swf itself for garbage collection. I see
that you are setting the loader to null but you still have the content on
the stage. Although it looks like you are trying to remove something from
the display list at position 0.
Are you sure that you are removing what you are intending to remove? Maybe
a more thorough emptying of the display list is in order such as a for loop
through the list, removing whatever might be on it.
And keep in mind that the garbage collection doesn't necc happen as soon as
you make something = null. It happens on a garbage cycle when Flash feels
like it, not when u want it to.
In Flash Player 9, the garbage collector's operations are deferred. This
is
a very important thing to understand. Your objects will not be removed
immediately when all active references are deleted. Rather, they will be
removed at some indeterminate time in the future (from a developer
standpoint). The garbage collector uses a set of heuristics that look at
the
RAM allocation and the size of the memory stack, among other things, to
determine when to run.

Yes I understand garbage collection(GC) and how it's SUPPOSE to work :)
However, there still remains the fact that my browser is at say 146,000K
private working set memory. Let my swf file sit there for a half hour or
more and now the working set is up to 300,000K. Refresh the page that the
swf is on and memory drops back to 146,000K. Now, turn off the mechanism
that kills the content swf and re-adds it to the main swf and viola, the
memory stays consistent at 146,000K.
So, is this code not removing the content.swf appropriately on my Timer?
Shouldn't GC be working appropriately and FF not adding additional
memory?
function timerHandler(event:TimerEvent):void {
trace(this.removeChildAt(0)); // remove from display list
mLoader.contentLoaderInfo.removeEventListener(Event.COMPLETE,
onCompleteHandler); // clear from memory
mLoader.contentLoaderInfo.removeEventListener(ProgressEvent.PROGRESS,

mLoader.unloadAndStop();// clear from memory
mLoader = null; // clear from memory
mLoader = new Loader(); // clear from memory
startLoad();
trace(timerHandler: + event);

PS I've been in IT since I was a kid and yes they still do mark the

with a special character. The only secure erase from a drive is to do
full

data
many times over until your paranoid self can feel good about it. However,
ultimately physically destroying the drive is the best way =)

Juan Pablo is correct, and it's important to understand why. (If you

Hello, this issue is killing me. I had a swf that loaded an xml file then
loaded images from the xml file and then killed the display list, xml,
images etc... then restarted based on a timer. Every time it reloads
however, I watch firefox take away memory consistently and when I refresh
that page memory use drops back to normal. So, I said screw this, I'm going
to create an empty swf and load the swf with all the magic in it and add it
to the empty swf. I figured if I add the swf to the main stage and kill that
one reference to the swf when I was done with it, I should have fixed my
problem. Here's my code. Can someone please tell me what is going on?

Try removing any listeners associated with that swf before unloading

Re: [Flashcoders] Memory leak in Flash projector
FYI, I can't speak specifically to either root cause or eventual effect/fix, but this entire thread has been routed to the Player team for triage and consideration (as will any subsequent suggestions/comments that follow fhere).

RE: [Flashcoders] Memory leak in Flash projector
I had similar issues and solved it by minimizing/restoring the App via a third party wrapper (SWF Studio in my case) in an Interval. It seems that by doing that the Garbage Collector is forced to run, it´s the same for Win.shide/show. However I was not able to find the memory leak in my code yet, it is quite complex with bunch of AS2 classes involved, but I *think* I deleted evere reference after use, but maybe I´m wrong with that,... hth André -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Darren Cook Sent: Tuesday, March 14, 2006 2:42 AM To: Flashcoders mailing list Subject: Re: [Flashcoders] Memory leak in Flash projector On Feb 25th 2006 Andreas Rønning wrote: This is very serious.

Re: [Flashcoders] Memory leak in Flash projector
Well, just today i filled 3 bugs reports on memory leaks and things that don´t get drawn correctly, all with test cases. v8 also has problems with the new ExternalInterface under IE, if the object tag is inside a form. Hope someone at Adobe fix all of this... On Fri, 24 Feb 2006 16:19:03 -0300, Andreas Rønning [EMAIL PROTECTED] wrote: This is very serious. The majority of my work is kiosk apps.
