Memory Leak in edited images?
I am using Captivate 4.0.1 Build 1658 (this means that the patch from May 2009 is applied) on Windows Vista.
The following has happened to myself and at least 2 other developers.
We edit a slide background image in Photoshop...when the movie plays, a flash of the previously unedited background shows. I have tried re-editing the background and it does not fix the problem. I have tried eliminating transistions and it does not fix the problem. I have noticed that this happens when background images are edited in Photoshop as well as within Captivate when bitmaps are pasted onto a slide background and then merged into the background.
I don't know if the correct term for this is a memory leak, but the closest mention of this problem I could find was here: http://blogs.adobe.com/captivate/2009/05/captvate_4_patch_update.html
I appreciate any help resolving this.
Thank you,
Beth

Memory leak in explict\images\content\used
Since about a week ago my girlfriend's Firefox 19.0.2 started to crash with low memory message. She's using a laptop with 3 gig of memory and Windows 7 32. Her add-ons are adblock, WeatherBug and some spellcheckers.
I reinstalled her browser and also installed Memory Fox plugin. It didn't help. Crashes occur once in one or two days after several hours of browsing.
I asked her to save the "about:memory" page when the low memory message appears. These are the first lines:
1,347.68 MB (100.0%) -- explicit
├──1,007.93 MB (74.79%) -- images
│ ├──1,007.71 MB (74.77%) -- content
│ │ ├──1,007.65 MB (74.77%) -- used
│ │ │ ├────601.40 MB (44.62%) ── raw

│ │ └──────0.06 MB (00.00%) ++ unused
│ └──────0.22 MB (00.02%) ++ chrome
She also sent me the page just after she started Firefox (with her pinned tabs) and there are no such memory figures.
Unfortunately I can't be more specific. She can't say if she changed something recently and she's also unable to cause it to happen when I am there.The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.

There seems to be a memory leak in the Image.getScaledInstance(...) method when used in the following code:
if(scanImage.getWidth(this) > scanImage.getHeight(this))
scanImage = scanImage.getScaledInstance(300, -1, Image.SCALE_DEFAULT);
else
scanImage = scanImage.getScaledInstance(-1, 300, Image.SCALE_DEFAULT);
}Any ideas why its leaking, or another way of doing scaling?hi
memory problems with this method seem to be common. here is another way of scaling images:
Iterator readers = ImageIO.getImageReadersByFormatName("gif");
ImageReader reader = (ImageReader)readers.next();
ImageInputStream iis = ImageIO.createImageInputStream(new File(path));
reader.setInput(iis, true);
ImageReadParam param = reader.getDefaultReadParam();
param.setSourceRenderSize(new Dimension(width, height));
BufferedImage thumbnail = reader.read(0, param);
this does not work for jpeg images and you need the sdk 1.4.2 in order to use ImageIO. previous versions do not have this framework. -
Severe memory leak in LR5 (CC release v5.0) when cropping (rotating) images
I have a Quadcore i7 iMac with 12GB of memory. When I start LR5, there is 8GB remaining. With nothing else being done, as a edit some images, and especially when I am rotating images in the crop tool to level the horizon, fI sometimes get the "OSX beachball" and the memory immediately drops from 8GB to 10-20MB!!! The disk goes crazy and LR5 and the entire machine slows to a crawl. The only way to bring it back is to Force Quit LR5. But this has happened with the same picture twice already and am getting ready to try #3.
Please fix this .... this is definitely a bug as there is no reason it should eat 8GB of memory for doing an image rotate.There are a number of bugs that have been logged against crop/roate in Lr5. The engineering team are currently working to fix these.

Memory leak in image rings on Linux
Hello all,
I have a very serious problem I didn't have in previous version of my soft and one of the only addition I've made recently is to use image rings. The soft uses 6Mb more every minute. If I remove the rings, it stops. It could be a wrong lead, so I'm trying to write a test case, but is there a list of identified memory leaks somewhere ?
THanks.
Solved!
Go to Solution.OK guys, there's a very serious leak on Linux, confirmed by the code below. Every time you change the value of a picture ring, either by clicking on the arrow of the picture ring or right-click on it (callback to SetCtrlVal), it uses 1 extra Mb of mem for a 512x512 pixel image !!!
Here's a sample code:
// Right-click the ring to cause memory leak
#include <stdio.h>
#include <stdlib.h>
#include <cvirte.h>

There are other issues as well:

- The anti-aliasing on a canvas doesn't compile.

We are implementing an AIR application that loads thumbnails
from the hard drive and uploads them to a remote server.
When bringing in large images, for example, when importing
five 2MB files into Image objects:
Flex reports that it is using 55MB
Windows reports using 220 Meg (viewing memory usage of
adl.exe in task manager)
After deletion of these image objects, the memory stays
allocated!! It is released when the application is closed.
Two issues I see:
1. Huge memory usage for image objects (I understand that JPG
files are exploded into BMPs). It limits our ability to load 10's
or 100's of images.
2. Bad Memory leak
OTHER THINGS WE TRIED:
1. Displaying images as inline html IMG tags.. Same memory
usage!
2. Taking a snapshot of the image and displaying that.
Problem, used way to much CPU
I hope these issues will be fixed before release time or we
are hosed.
PLATFORM: Windows XP Professional, service pack 2Hi
Have you tried the FB3 profiler to investigate why memory is
not getting deallocated?
You can use the loitering objects panel to track the back
references for the objects in memory. If you find that image object
is not being referenced by anything else. Can you file a bug at
http://bugs.adobe.com/flex
with a small test case.
Also as you know that jpg will be translated into bitmap. The
amount of memory required will be determined by the pixels in the
image. Each pixel will be 4K

Editing in aperture is doing crazy things. I've read that it is memory leaks. Whats the cure?
Aperture is doing crazy things while editing like leaving spots on faces when using skin smoothing tool among other things. Closing and reopening fixes it but how annoying. I've read that it is caused from memory leaks. What do I do to fix this?
What is your Aperture version?
And your MacOS X version?
With Aperture 3 make sure you have the latest versions, Aperture 3.5.1 and OS 10.9.3.
The memory leaks you are referring to occurred with MacOS 10.9.1 and onscreen proofing enabled.
If yor versions are current, check your plug-ins for compatibility. -
Applescript Image Events appears to have memory leak (or I don't know what I am doing)
Using Image Events to create images and thumbnails for a website. The following code results in very large memory leaks in Image Event process. I have documented results of test runs in the comments.
The leak (or poor coding on my part) results in a total system halt if I attempt to process more than about 400 images at a time. Basically, I run out ot physical memory. I am running a new model 13" MBP with 8GM RAM. I have to manually stop Image Events to reclaim the memory (or reboot of course).
Any help/suggestions would be appreciated.
(* test memory leak in Image Events *)
tests with 58 photos selected in iPhoto
5.7 MB left in Image Events after run with only open and close
22.0 MB left in Image Events after run with open, save and close
45.9 MB left in Image Events after run with open, scale, save and close
A run with 382 photos selected used OVER 3.8 GB (gigabytes) and the
mac ran out of physical memory so I had to stop the test.
tell application "Finder"
set imageFolder to folder "test" of home as alias
end tell
tell application "iPhoto"
set currPhotoList to the selection
repeat with currPhoto in currPhotoList
log name of currPhoto as string
set theImagePath to image path of currPhoto
tell application "Image Events"
launch
set theImage to open theImagePath
scale theImage to size 128
save theImage in imageFolder as JPEG with icon
close theImage
end tell
end repeat
end tell
--- end of code exampleDoes the following code do any difference? Most likely no I guess… but better try than nothing.
tell application "Finder"
set imageFolder to folder "test" of home as text -- instead of “as alias” (see theTargetPath below)
end tell
set theImagePaths to {}
set theImagePathsRef to a reference to theImagePaths -- faster with big lists
tell application "iPhoto"
set currPhotoList to the selection
repeat with currPhoto in currPhotoList
log name of currPhoto as string
get POSIX file (image path of currPhoto) as alias -- faster ?
copy result to the end of theImagePathsRef
end repeat
end tell

Sun Application Server Platform Edition 8.2 Memory Leak!!
Hi there,
I've been testing a benchmark tool and been used App Server with Adventure Builder deployed as my SUT.
What happens is that I've found that the server crashes within few minutes with a memory leak problem. I was testing a version that has already set a timeout to the file descriptors and it stayed up and running for some hours, but we can observe the memory decreasing too.
I've used the netbeans profiling with a "no-alterations" App Server and it crashes after 20 minutes or so.
I've associated the increase of memory (about minute 4) with the creation of threads called iMQReadChannel that kept running until the server crashes.
Can you help me with that?
Is there a bug fix for this?
By the way, can anybody tell me some applications based in web services that I could use as a SUT? it could be some BPEL examples..
Thanks in advance
Francisco VeigaWhat exactly are the symptoms of the crash? If it's actually a crash and a core dump, then if you can provide more details on that (hs_err_pid file and any associated messages), we can file a bug against the JVM. If you get memory exceptions, what specifically do they say?
Also, which JVM are you actually using? There are some known bugs with JDK 1.5.0_06 and earlier around memory and file descriptor usage; we recommend that you use JDK 1.5.0_09 or a JDK 6.0 beta. For that matter, you will see better performance in general with version 9.0 of the appserver

Bug:4705928 PLSQL: Memory leak using small varrays
We have Oracle version 10.2.0.1.0
We have a problem with a procedure.
In our scenario we make use of VARRAY in the procedure to pass some filter parameters to a select distinct querying a view made on three tables.
Unfotunately not always execution it is successful.
Sometimes it returns wrong value (0 for the count parameter), sometimes (rarely) the server stops working.
We suspect that this is caused by a bug fixed in versione 10.2.0.3.0
Bug:4705928 PLSQL: Memory leak using small varrays when trimming the whole collection and inserting into it in a loop
We suspect this becasue we made two procedure the first (spProductCount) uses a function (fnProductFilter) to calculate the values of a varray and passes them into the select,
while in the second procedure (spProductCount2) parameters are passed directly into the statement without varray
and there are failures only in the first procedure.
On the other hand on another server 10.2.0.1.0 we never have this problem.
The instance manifesting the bug runs under shared mode, while the other is under dedicated mode.
Turning the first one to dedicated mode makes the bugs disapear.
Unfortunately this is not a solution.
In the sample there are the three table with all constraints, the view, tha varray custom type, the function and the two procedures.
Is there someone that may examine our sample and tell us if the pl/sql code corresponds to the bug desciption.
We also want to know if it's possibile that the same server running under different mode (SHARED/DEDICATED) doesn't behave the same way.

Using VARRAY was the only way I found to transform comma seprated text values (e.g. "'abc', 'def', '123'") in a collection of strings.A varray is just a functionally crippled version of a nested table collection type, with a defined limit you probably don't need. (Why 100 specifically?) Instead of
CREATE OR REPLACE TYPE varray_params AS VARRAY(100) OF NVARCHAR2(1000);try
CREATE OR REPLACE TYPE array_params AS TABLE OF NVARCHAR2(1000);I don't know whether that will solve the problem but at least it'll be a slightly more useful type.
What makes you think it's a memory leak specifically? Do you observe session PGA memory use going up more than it should?
btw good luck with all those quoted column names. I wouldn't like to have to work with those, although they do make the forum more colourful.

Hello,
I just found a memory leak in my code caused by the SystemTray, but I don't know if that is me that misused SystemTray (I add a trayIcon, then remove it, then add an another one, and so on). I know how to get around that problem, but I don't know the origin of it (my code, java bug ?). So I made the following code reproducing that leak. If someone can give me idea or advice :-)
class MyThread extends Thread {

public MyThread(ReferenceQueue<?> referenceQueue) {
this.referenceQueue = referenceQueue;
@Override
public void run() {
System.out.println("Starting ...");

System.out.println("We release a TrayIcon");
} catch (InterruptedException ex) {

}------------------------------------------- ADDED -----------------------------------
P.S. :
- the toto array in MyPopup is there in order to obtain quicker a OutOfMemory (OOM)
- you may change your java parameter by fixing the allowed memory size in order to have a OOM quicker (-Xms30m -Xmx30m)
- you must have an image in order to test this code (and set the path where <AN IMAGE HERE> is)
- if you remove the following lines there is no OOM :
tray.add(trayIcon);
tray.remove(trayIcon);
so it seems to me that TrayIcon is the origin of the OOM
- the weak reference is there in order to see when a trayIcon can be garbage collected
Edited by: lemmel on May 5, 2009 7:22 AM - added commentsSo I did the test and:
- you were right about the vector, but this one was added only for debugging purpose (find the OOM cause)
- your code sample get a OOM with my computer as well as mine (with the vector removed obviously); I made some alteration to your code see below
could you try changing your java memory settings (see below) ?
P.S. :
- I first tried with your code as it was, got the OOM, then decided to give some time to the garbage collector (and later to force a call to it) by adding the lines with the tag ADDED
import java.awt.*;
import java.awt.image.BufferedImage;
static class MyPopup extends PopupMenu {
public static void main(String[] args) throws Exception{
SystemTray tray = SystemTray.getSystemTray();
BufferedImage image = new BufferedImage(16, 16, BufferedImage.TYPE_INT_RGB);
int i = 0; //ADDED
while (true) {
PopupMenu popup = new MyPopup();
TrayIcon newTrayIcon = new TrayIcon(image, "Frame Title", popup);
tray.add(newTrayIcon);
tray.remove(newTrayIcon);
if((i%10)==0) { //ADDED
System.gc(); //ADDED
System.runFinalization(); //ADDED
Thread.sleep(100); //ADDED
} //ADDED
i ++; //ADDED
}I removed the array trick in the MyPopup class in order to be able to do at least one loop (see my settings below)

PGA memory Leak issue along with TNS: listener could not hand off client connection
Hi,
We have two Oracle Database instances in a 32 bit Standard Edition Windows OS machine with 3 GB RAM : 1) 1525 MB (SGA+PGA) 2) 515 MB (SGA+PGA)
Recently we upgraded the RAM from 3 GB to 4 GB. Subsequently we upgraded the SGA + PGA of the 2nd instance to 771 MB.
This has resulted into PGA memory leak issue reported in the alert log file and trace file.
Reverting back the SGA+PGA size to 515 MB solved the issue.
Is this issue related to Address Windowing Extension (AWE)?
Is the reason related to Total memory for all the cumulative Oracle instance should be < 2GB.
How to solve this?

EXTENT 3 addr=70A50008There may be something fixed in the patch that gives the error rather than mysterious hangs. I would prefer that, myself. There may be something in the patch that changes how Oracle allocates user, system and program areas.
At some point you spend more trying to limp things along in a growing environment than simply upgrading. 32 bit environments these days is an indicator that management is figuring some false economies. But that's their prerogative.
The PGA can be affected by many things, not least of which is how the application uses it. Much has been written about it, my own experience has been more is used than most people say. But that is probably just my app. Note there are different ways to set it, and a parameter with "target" in it might not be a hard limit. Different execution plans for the same code may use different amounts of memory - there can even be situations where forcing some code to use a sort area instead, or even forcing more operations to disk, can free up more pga for everyone else. It depends. But that's why I look at multi-pass operations in dbconsole. -
Memory Leak in latest Safari (5.0.4)?
Since I updated to the latest Mac OS/X update Safari's memory usage seems to be increasing in a way that looks like a memory leak. I usually leave my mac running all of the time and find that after a few days Safari is using over a 1GB of real memory and 3-5GB of virtual memory. Sometimes it also seems to freeze — with the disk churning in the background when I try to switch to it.
It may be related to viewing high-resolution images (it seems to happen more often if I view very high-resolution pictures, for example Nasa Picture of the Day).
Anyone else seeing these issues? Occasionally it crashes when I try to kill it — I'll post the dump info next time.Hi,
Delete the Safari cache and history more often, not to mention restarting your Mac.
Disable plug-ins in Safari / Preferences - Security. See if that helps.
Check Safari / Preferences - Extensions.
Occasionally it crashes
Post a crash log so we can try and help if emptying the cache and history trail / plugins / Extensions aren't the issue.
If Safari has just crashed, press the Report button on the CrashReporter dialog box to view the crash information.
Now copy/paste the entire contents of the Crash Reporter window into your reply here. If the crash report dialog does not appear or the crash is hard to reproduce, crash logs can be retrieved from the ~/Library/Logs/CrashReporter> folder.

Has Lr 5 fixed the Export memory leak?
Has anyone confirmed that the memory leak in Lr 5 Beta when exporting images has been fixed in the Lr 5 release? In the Beta all 16Gb of my machine's RAM could be quickly consumed if I exported a large number of images. I could release the memory by simply clicking an image in Grid view but it would be nice to have the export behave properly.
No, still nothing. This is about halway in, and for good measure I threw in a second export on top.
You can see the CPU getting a lot busier (confirming that breaking an export into two speeds it up) - but memory usage is still rock solid. Incidentally, this last one is exporting to TIFF, which seems to use a little less memory than exporting to PSD. No idea why that should be.
Do you have any plugins that could cause leaks?
Edit: OK, so that's cleared up then. I never tried the beta.
Maybe you are looking for
