There seems to be serious flash memory leak in ie7
Hi.. I have run into a serious memory leak issue with flash on
internet explorer 7.0.5730.13 (everything works with firefox). It can be
seen clearly browsing open flash charts site. Here are steps to
reproduce:
1) go to
http://www.websector.de/blog/2007/10/01 ... wsmonitor/
2) click start on WSMonitor
3) File->New Window paste following address in address bar and click
enter: http://teethgrinder.co.uk/open-flash-ch ... hollow.php
4) click from chart to chart and see each time how memory increases...
This does not happen with firefox.
Independently to trouble shoot it wasn't any code I confirmed by making an swf file with actionscript with simply following:
package {
import flash.display.Sprite;
public class main extends Sprite {
public function main() {
trace("starting3");
hello, can you try to replicate this behaviour when you launch firefox in safe mode once? if not, maybe an addon is interfering here...

APEX 4.1.1 Memory Leak in IE7
Hi,
We busy upgrading our apex and db from 3.0/10G to 4.1.1/11.2G and notice that there appears to be a memory leak when using APEX. At one stage we have had IE7 using over a gig of memory.
When you load or refresh your page IE7 seems to grab on average 2-5MB of memory for each page load. At first we thought it may have been our apps or setup but this also happens when we go to app 4550 page 1 on apex.oracle.com.
How to replicate:
Open task manager to view the Memory Usage.
Using IE7
1. Go to http://apex.oracle.com/pls/apex/f?p=4550:1
2. Go back to Task Manager and note the readings once the CPU Usage for iexplore.exe has stablised to 0.
3. go back to IE7 and press F5
4. Repeat steps 2-3 and you will see the Memory usage increases.
We think this maybe due to a few jQuery UI memory leaks within IE7 and thought this bug ticket maybe of interest http://bugs.jqueryui.com/ticket/7666 (Slightly different versions but similiar experiences)
Could someone else confirm that they also experience the increasing or have had similiar problems and managed to resolve it?
TBH, it wouldn't be an issue to use another browser like Firefox to access the builder but this also affects the applications if they include APEX standard Javascript and CSS.
Thanking you in advance.

Don't have exact steps for replication or precise numbers, but I have noticed this in passing. On the junk that my client considers a PC suitable for web development the typical IE7 memory footprint with the APEX 3.0 builder and several other tabs running is about 52MB. Add APEX 4.1.1 and it climbs constantly until I have to pull the plug when it gets north of 150MB as the PC can't take it.
As well that I also have Firefox and 4.1.1 is still experimental at that site...
At the moment I don't have to resolve it and if I did the only option I'd propose is the replacement of IE7.

I saw that eariler this week. I do agree with the concept though.So take appropriate action: charge extra for IE7 support.
The amount of work and effort involved in making our website look normal on IE7 equalled the combined time of designing for Chrome, Safari and Firefox.Is entirely accurate. If it's stated as a requirement, itemise it as an extra on the quote.
Educate management and bean counters: show them the one line of standards-compliant CSS that's all that is necessary in Safari, Chrome, Firefox and Opera (and just possibly in IE8/9/10), how it isn't supported in IE7, and the tortuous hacks and workarounds that are required to get something equivalent working there. -
Safari 3 / Flash memory leak
I recently upgraded to Safari 3.0.4 and am noticing a huge memory leak problem if I leave a Flash-enabled page open for any length of time. I monitor the Virtual Memory usage of Safari using Activity Monitor. Usage goes from around 280MB to as high as 2.65GB before I have to shut down Safari for my 1GB machine to be usable.
See additional discussion here:
http://forums.macrumors.com/showthread.php?p=4610322
Does anyone know if this is a webkit issue, Apple/Safari issue, or a Flash issue?Hi
Welcome to Apple Discussions
On my machines, Safari has had challenges with World Leaks since the beginning (right now it is using 750 mb of RAM with 38 tabs open on one window). A bit excessive, however, it's not a red flag given the amount of RAM and processor speed of the iMac. Nonetheless, it ought to be a lot more efficient with RAM usage. I would use the latest WebKit build, however, some of my Safari add-ons would be incompatible.
BTW, I too see jumps in usage, especially when accessing Flash content. The "only" way out is to quit/restart. Important to send feedback to Apple via the Safari Menu>Report Bugs to Apple. -
Memory leak? & ie7 partial triggers
Hi all,
I'm running Jdev 11.1.1.0.3 against a 10.3 WLS
I've made a few try with adf faces & I'm running now against a problem looking like memory leak.
I'm working with a parent/child tables in separate showdetailitems container having about 5/6 columns on the child table.
When I run the application it works perfeclty.
If I put 10/12 columns on the child table the application stalled when I go in the child showdetailitem (Retrieving data)
Except if the child table doesn't have more than 3-4 rows (then it works great)
I have another problem with IE7 making objectRequired error on any adf page with partialtrigger.
IE7 say the error is located arround the lines
this.headers= new Object();
this.xmlhttp= new XMLHttpRequest();}
AdfXMLRequest.prototype.toString=function()
in _all-11.1.1.0.0.js file
Any hint on any of the two would be appreciated, I'll try re-installing ie7 meanwhile. ^_^hi Frank (great tutorials!), Peter.
Frank, Regarding ie7 I've noticed we're not a lot to have this problem, I use firefix meanwhile hoping ie8 fixes the issue. Still I'm ready to fill a SR if you think it's worthwhile.
Peter, Thx for the idea, i've set contentdelivery to immediate & get further errors ^_^
When I clic on the ShowdetailItem (third one) It goes back to the first one with this error (sorry you'll guess I'm french)

Hi Everyone,
Simple logic but every time increase the memory.
Any one help me out from this.
var container:MovieClip = new MovieClip()

remove.addEventListener(MouseEvent.CLICK,clearloop)you're not using the code i suggested.
remove all your code.

Memory leak in LoadVars?
Hi,
In one of our apps, we've a need to continuously load new
data (using Loadvars) every x seconds from the server. However, I
seem to be having a memory leak issue when doing the same. Consider
the following skeletal code:
var myVars:LoadVars = new LoadVars();
myVars.onHTTPStatus = function(httpStatus) {
this.httpStatus = httpStatus;
myVars.onLoad = function(success:Boolean){
//trace("Data loaded: " + success);
var int:Number = setInterval(loadData,2000);
function loadData(){
myVars.load("
http://server/RealTime/ISv3.asp?UpperLimit=100&lowerLimit=0");
stop();
Here, I'm loading the data from an ASP page every 2 seconds
in the same LoadVars object. Now, when I run this movie continuosly
for a few hours, there's a huge increase in memory usage of this
movie. Using the profiler, I've made sure that the memory is
increasing for the Flash movie and not InetInfo or any other
process/thread.
Now, here we do not have anything else in the movie (no
visuals, no calculations etc.) and more over we're re-using the
same LoadVars object to reload data. Any pointers as to what we
could be doing wrong? Any help would be greatly appreciated.You might try setting it up with two LoadVars and using
sendAndLoad. And
also you have no guarantee your call has finished before your
trying again.
You could use a simple boolean to only call the asp after the
prior call has
finished.
var mySender:LoadVars = new LoadVars();
var myReceiver:LoadVars = new LoadVars();
var doneLoading = true;
mySender.onHTTPStatus = function(httpStatus) {
this.httpStatus = httpStatus;
myReceiver.onLoad = function(success:Boolean){
doneLoading = true;
//trace("Data loaded: " + success);
function loadData(){
if(doneLoading){
doneLoading = false;
mySender.upperLimit = 100;
mySender.lowerLimit = 0;
mySender.sendAndLoad("
http://server/RealTime/ISv3.asp",
myReceiver);
var int:Number = setInterval(loadData, 2000);
stop();

Memory Leak Issue With Win7 64 bit and Youtube.
I have a Win7 64 bit using IE9 with version 11.4.402.265 installed. 4 MB installed.
Whenever I go to Youtube or Liveleak, and watch videos, over time it uses up to 4gigs of my memory! Even if I close the window, it does not free up the memory until I Ctrl/Alt/Delete and shut down the window(s).
I normally only keep open 1-2 windows. Google toolbar is about the only thing installed. I can open 5 and more tabs, but as long as the site does not use flash, I don't have issues and each window usually uses under 200k memory watching them in task manager.
When I go to open and watch a youtube video, it slowly climbs to 200k and within an hour, I can be at 2 gigs or more memory and up to 4 gigs within 2 hours (or sometimes much sooner). Closing the window does not release the memory until I end task on it and then after a minute or so, the memory seems to clear and everything is back to normal.
I searched the forums and seems lots of users, report memory leaks, some using yahoo toolbar installed, which is not my case. I do use yahoo as my e-mail address, no idea if that is related or not. I had the same issue when I had the prior Flash version installed, this has been going on for months. Right now having only this window open, using 129, 192 memory. If I open one more window (using the 64 or 32 bit browser) and start youtube, the memory in that window keeps climbing about 50-100kb a second, so it adds up quickly. I have kaspersky running in the background and that is about it other then my nvida driver setup.
Really frustrating that so many people here and across the internet have reported this. I did have IE8 a few weeks ago and still had the same issue, upgraded to IE9 to see if that helped.
Interesting side note, if I pause a video, it slows way down on the memory leak, but still rises at a slower pace. I don't know if this is an IE thing or Flash. I have had this setup since 2009 and don't recall having issues with IE7. I use Youtube so much as a teaching instrument as a music teacher, so constantly have lessons going on it.
Thanks and hope someone has come up with something. I also build computers and have done some programming, so I could modify a file if needed with clear instructions.This could be similar to bug https://bugbase.adobe.com/index.cfm?event=bug&id=3334814

We seem to be having a memory leak problem with our first BC4J application. Using the memory profiler in JDev(9.0.2.1) I have noticed that every time I check out an application module using Configuration.createRootApplicationModule() an oracle.jbo.common.ampool.SessionCookieImpl object is created. Once the application module is checked back in using Configuration.releaseApplicationModule(am,false) the SessionCookieImpl object is still allocated. This happens on almost every page in my application, so the number of SessionCookieImpl object grows very quickly, and they never seem to get deallocated, even after several hours. Under heavy usage this is causing a huge problems.
I am using the "Stateless" release mode in the configuration, and module pooling seems to be working flawlessly. It seems to me that there should be someway to deallocate these objects once a module is checked in.
Am I doing something obviously wrong? Does anyone know how to fix this? Please help!
Here are the config options I am using
<AppModuleConfig name="MasterModuleLocal">
<jbo.project>WBS</jbo.project>
<AppModuleJndiName>###.###.wbs.bc.MasterModule</AppModuleJndiName>
<DeployPlatform>LOCAL</DeployPlatform>
<JDBCName>prod</JDBCName>
<RELEASE_MODE>Stateless</RELEASE_MODE>
<jbo.ampool.dynamicjdbccredentials>false</jbo.ampool.dynamicjdbccredentials>
<ApplicationName>###.###.wbs.bc.MasterModule</ApplicationName>
<jbo.poolminavailablesize>0</jbo.poolminavailablesize>
<DBconnection>jdbc:oracle:thin:@***.***.***.***:1521:prod</DBconnection> <jbo.doconnectionpooling>true</jbo.doconnectionpooling> <jbo.ampool.minavailablesize>0</jbo.ampool.minavailablesize>
</AppModuleConfig>This made complete sense to me, so I rushed into work this morning. I haven't looked at that parameter since i first started doing some experiments with bc4j more than a year ago. At the time i assumed that using true would not put the module back into the pool, so I never tried using it.
When I got to work this morning, i changed this param and unfortunately I could not see any difference at all in the behavior of the application.
This is still a huge problem because we have several objects getting created every time a request for a module is made, and these are never deallocated. After just a few hours of normal use, these objects have consumed huge chunks of memory on the server. -
SQL Server 2008R2 SP2 Query optimizer memory leak ?
It looks like we are facing a SQL Server 2008R2 queery optimizer memory leak.
We have below version of SQL Server
Microsoft SQL Server 2008 R2 (SP2) - 10.50.4000.0 (X64)
Jun 28 2012 08:36:30
Copyright (c) Microsoft Corporation
Standard Edition (64-bit) on Windows NT 6.1 <X64> (Build 7601: Service Pack 1)
The instance is set MAximum memory tro 20 GB.
After executing a huge query (2277 kB generated by IBM SPSS Clementine) with tons of CASE and a lot of AND/OR statements in the WHERE and CASE statements and muliple subqueries the server stops responding on Out of memory in the internal pool
and the query optimizer has allocated all the memory.
From Management Data Warehouse we can find that the query was executed at

We have encountered this issue already two times (every time the critical query is executed).Hi,
This does seems to me kind of memory Leak and actually it is from SQL Optimizer which leaked memory from buffer pool so much that it did not had any memory to be allocated for new page.

Can you post complete DBCC MEMORYSTATUS output which was generated in errorlog. Is this the only message in errorlog or there are some more messages before and after it.
select (SUM(single_pages_kb)*1024)/8192 as total_stolen_pages, type
from sys.dm_os_memory_clerks
group by typeorder by total_stolen_pages desc
and
select sum(pages_allocated_count * page_size_in_bytes)/1024,type from sys.dm_os_memory_objects
group by type
If you can post the output of above two queries with dbcc memorystaus output on some shared drive and share location with us here. I would try to find out what is leaking memory.
You can very well apply SQL Server 2008 r2 SP3 and see if this issue subsides but I am not sure whether this is fixed or actually it is a bug.

Firefox 4.0 RC has huge memory leak + slow down problem
Firefox 4.0 RC Seems to have a huge memory leak issue. After leaving the program open for around half an hour the RAM usage climbs to over 1 gb.
However, I have 12 gb of physical ram, so firefox staking 1 gb for itself is not too big of a problem (and is probably a blessing as it means it's caching more data), but the problem is that the UI begins to slow down and become clunky after about 30 minutes.
Browsing, switching tabs, even typing becomes jittery and not very responsive.
This happens regardless of how many tabs I have open.
Now it's also crashing every once in a while.Even with Firefox 4.0 (Release) running in Safe Mode, with all add-ons and themes disabled, I'm still inclined to think there's something screwy going on here.
I was watching Page Faults/sec, Page File Bytes and Working Set in Performance Monitor and tailing the Privoxy log for requests. Even with Firefox minimized and "doing nothing" (making no requests, anyway), over the space of a 10 minute period the Working Set grew from 244,375,552 bytes to 274,939,004 bytes (averaging 50,939 bytes/second). This behaviour doesn't seem consistent though - sometimes it doesn't seem to grow at all.
Additionally the Page Faults/Sec went nuts, accompanied by a step in Page File Bytes and Working Set, whenever a request got made to http://safebrowsing.clients.google.com/safebrowsing/downloads which seems to happens on a regular basis (approximately every 30 minutes). -
Oracle JDBC Thin Driver Memory leak in scrollable result set
Hi,
I am using oracle 8.1.7 with oracle thin jdbc driver (classes12.zip) with jre 1.2.2. When I try to use the scrollable resultset and fetch records with the default fetch size, I run into memory leaks. When the records fetched are large(10000 records) over a period of access I get "outofmemory" error because of the leak. There is no use increasing the heap size as the leak is anyhow there.
I tried using optimizeit and found there is a huge amout of memory leak for each execution of scrollable resultsets and this memory leak is propotional to the no of records fetched. This memory leak is not released even when i set the resultset,statement objects to null. Also when i use methods like scrollabelresultset.last() this memory leak increases.
So is this a problem with the driver or i am doing some wrong.
If some of you can help me with a solution to solve this it would be of help. If needed i can provide some statistics of these memory leaks using optimize it and share the code.
Thanks
RajeshThis thread is ancient and the original was about the 8.1.7 drivers. Please start a new thread. Be sure to include driver and database versions, stack traces, sample code and why you think there is a memory leak.

Memory Leak in QTPlugin ? (QT7, and QT 6.5+)
Trying to track this down, there is a problem with a memory leak when doing a endless loop quicktime sequence of images. To get the loop, I've created a SMIL file with the images, then have a HTML page that uses the EMBED tag to reference these SMIL files via QTNEXTxx, with a final GOTO0 to get back to the start.
It works, but if you watch the process with Activity Monitor (or top) you can see that memory consumption grows over time and will eventually crash whatever browser you are using. This happens if I open the HTML file with Safari, iCab, Opera, Firefox, RealPlayer, etc...
Very simple example with even one image will leak memory, albeit at a slower pace:
HTML: (replaced brackets with curly braces)
{html}
{head}
{title}radarLoops.html{/title}
{/head}
{body bgcolor="#000000"}
{center}
{embed src="file1.smil BGCOLOR="#000000" autoplay="true" controller="false" width="800" height="620" pluginspage="http://www.apple.com/quicktime/download/" QTNEXT1="GOTO0"}
{/center}
{/body}
{/html}
file1.smil:
SMILtext{smil xmlns:qt="http://www.apple.com/quicktime/resources/smilextensions" qt:autoplay="true" qt:time-slider="false"}
{head}
{layout}
{root-layout width="800" height="620" background-color="black" /}
{region id="region_1" left="0" top="0" width="800" height="620" fit="fill" /}
{/layout}
{/head}
{body}
{seq}
{img src="TEST.JPG" region="region_1" dur="1s" /}
{/seq}
{/body}
{/smil}
To workaround this issue, we had to revert to a 10.3.x system with QT6.4.x on it, reverting a 10.3.9 to QT6.5.x didn't work. A Tiger installation with 7.0.3 doesn't work either, it leaks like a sieve.
How can I debug this?Write a main() that does the polling in a tight loop 1000 times. Then System.gc(); Thread.sleep(1000); System.exit(). Run the thing with -Xrunhprof. Observe the "live bytes" and "live objs" columns in the generated java.hprof.txt file. Anything that strikes as suspicious? If every polling round leaks one object, there's likely to be 1000 (or N*1000) of something live. Make sure the leak is in the polling routine by running it 1,000,000 rounds and getting an OutOfMemory.

How to track Memory Leaks in 3.6.8?
I've been noticing for several updates now that I seem to be getting major memory leaks. Firefox starts off around 1-200,000 K memory usage in task manager, but within a few hours it will be past 800,000 K. Now, the things I've seen so far talk about disabling plugins and all to find the problem, but this doesn't happen immediately, so disabling things one by one isn't very feasible. How can i track the memory leak to a specific plugin, or else make it leak much, much faster so I can do the one by one thing?
== This happened ==
Every time Firefox opened
== A few updates agoWell, It just has taken a turn for the worse... In the attached screenshot you can see firefox took 1.123.112kb out of my memory at which point the GUI became unresponsive. This has actually happened before, but not as soon...
I had 18 tabs open (but at the moment I have all of them opened again after a restart of firefox and it takes 143.988 kb at this very moment, which still is a lot actually). My computer has 4gb RAM-memory of which 46% is in use at the moment according to windows task manager.
It would be great if the whole tabstructure and maybe the garbage collector for the TraceMonkey javascript engine was reviewed... This might point out where the memory leaks are located. -
Looking at the release notes for firmware v1.1.21 I noticed that one of the known issues with this product line is a memory leak issue with UPnP.
I am looking to purchase new devices for my network and this product line is one that I'm looking into.
However, I plan to use UPnP extensivley on my network and will not purchase a device that has problems with it.
Is there a time frame for this memory leak to be fixed?
Something like a memory leak that can cause a device to lock up or reboot should be high priority to be fixed.The UPnP leak was found late in testing. I don't have too much info on it, but I know they are looking to fix it soon. I don't have a time frame and I believe the leak was small, but if you are using UPnP extensively, I would wait to avoid down time.

Since the last update today, Firefox seems to got a huge memory leak. After one hour idle on some pages it was up to 750MB memory usage, and constant 100% load of one CPU core.
Looks like something is not going well with the garbage collection, if I visit http://www.robertsspaceindustries.com/forums/forum/forum-category-2/ for example.
Had to disable the graphic hardware acceleration, because of the newly introduced "clear type" font bug.
Edit: May also be related to mail.google.com, which I have running in an app tab.For what it's worth, I had exactly the same problem (except that it's on Linux) since the upgrade to 17.0. When I disabled greasemonkey, the problem instantly disappeared, so it looks like the compatibility with greasemonkey got broken.
Likewise, I'm very disappointed with the frequent bugs/annoyances that come with the rolling upgrade system; I find myself more and more using Chromium because of it. Mozilla really needs to give people the option to run a stable branch that receives security updates only.
