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.

Problem Report: Severe memory leak in Flash Player 9.0
Summary
Flash player 9.0 is prone to a severe memory leak when
playing SWF files produced by Captivate 1 containing full-motion
recordings.
Versions affected
The problem reproduces with Flash player 9.0 (Flash9.ocx,
Version 9.0.16.0) hosted in either Internet Explorer 6.0 or Mozilla
Firefox 1.5 on a Windows XP SP2 system.
The problem does not reproduce with Flash player 8.0
(Flash8.ocx, Version 8.0.22.0) in the same environment.
Description
After a few minutes playing a SWF file produced by Captivate
1 containing a full-motion recording recorded with Captivate 1, the
host browser ends up using more than a gigabyte of memory, and the
playback of the movie slows down to a halt, together with
responsiveness of the whole system.
Impact
Our organization develops E-learning content with Captivate 1
for various customers, mostly Fortune 100 companies.
This bug severely limits our ability to deliver content to
our customers.
Steps to reproduce
1. Using Captivate 1.01.1418, create a “blank
movie” with default settings.
2. Use the “Record” button and begin recording a
full-motion movie for about 2-4 minutes. For the purposes of this
bug, it is enough to record a user typing random text in a Notepad
window resized to fit in the default 800x600 window.
3. After recording the full-motion movie, publish the
Captivate movie as a “Flash (SWF)” movie, using default
settings (making sure that the “export HTML” checkbox
is selected).
4. Open the published movie’s HTML file with a host
browser, making sure that the browser is using the Flash 9.0
player.
5. While the movie is playing, watch the memory usage of the
browser process using Windows Task Manager, and you will see that
the values of the “Mem Usage” and “VM Size”
counters keep increasing until the system becomes unusable.Also see:

issues: page faulting
Flash is also generating around 300 page faults per second.
This can be observed by following the instructions in the link

Severe Memory Leak in 10.1.0.3
Hi,
There exists a severe leak of element names (QxName), when garbage collecting elements, which has been constructed as;
XMLDocument doc = new XMLDocument();
doc.createElement("AnyName");
After GC references in oracle.xml.util.QxNameHash$WeakValue still exists.
It's very easy to reproduce;
for (;;) {
XMLDocument doc = new XMLDocument();
doc.createElement("AnyName");
thanks,
-- peter
We are building products, which relies on Oracle XML technology, and this is a major issue (P1) in large 7/24 production systems. Would
appreciate any suggestion to work-around...Additional information;
First a minor correction, the actual leak is not direct references element names, but rather weak references (left after GC) to such names (each weak reference allocates 32 bytes).
In our system the leak is approx. 0.67 MB/hour, or 16MB during a 24h period, and it processes about 100 XML documents/second.
The problem seems to be very trivial (deep knowledge in Java and GC is not required, even though the semantics of weak references is a bit fuzzy), and I really hope you guys will take an appropriate action...
thanks,
-- peter
PS My previous example works fine in the OptimizeIT tool, due to the specific GC behavior. If you'll do the same in a plain JVM, then it's best to reduce the heap size, and allocate something large before creating the XML element. -
Severe Memory Leak in Mavericks When Downloading
I have a Macbook Pro running 10.9.3 with 10 gigs of RAM. The RAM works fine and checked out fine in AHT. Since updating to 10.9.3 when I download things from Steam, iTunes, Mac App Store, etc. the available memory goes significantly down when only running one of the programs at a time. It gets to dangerously low points around 7-8 MB available (monitored by memory clean and activity monitor.). The faster the internet connection, the faster the memory is depleted. It's like its downloading to ram and then writing to disk instead. When it gets too low I purge the memory through a terminal program I wrote as it clears up more memory than memory clean.
Even after cleaning the memory it still depletes fast if I'm downloading something. However If I'm not downloading anything on those apps they use little to no memory at all.1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off merely by the seeming complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the behest of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line

to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start Time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Severe memory leaks on certain sites
Followed FAQ advice and installed Leak Monitor add-on. Occasional leaks occur while surfing. On one site (Chase Bank online banking) leaks occur so often I can't keep up with closing the Leak Monitor alert windows. Why does this occur on particular sites? Is it a problem with the site or with Firefox (3.5.9)? What can be done about it? Thanks.

Memory Leak and 100% CPU in slapd process when using Open Directory OS X 10.8.5
Has anyone seen the slapd (LDAP daemon from OpenLDAP which OS X Server uses) run away when running Open Directory? We've tried disabling replication but it doesn't seem to matter. The slapd process will start up and take up about 400MB and then at night will consume all the available memory and crashing the server.
Any thoughts? Any benefit in upgrading to Mavericks' Server app?
Thanks,
John@Strontium90

The deadlock from what I can tell is a more of a warning from OpenLDAP, but it is a common pattern and occurring every few minutes.
Not much useful in slapconfig.log.
Any insights? Thanks so much.

Observed Memory Leak When Invoking Controls in Workshop 8.1 sp3
Hello,
We have developed a website using Bea Portal 8.1 sp3. In testing we have observed severe memory leaking problems which occur also in the production environment where WebLogic is not being run in debug mode. The troubleshooting was started by profiling the testing environment (running in debug mode) using JProfiler. The leak was isolated to occur especially in control method invocation via InvocationHandler call. The object being leaked was character array. After further study we noticed that the method call which this framework InvocationHandler was delegating had especially large return value. Namely a map consisting of ~5Mb of content. After reviewing our own code for possible leak source and coming up with nothing obviously wrong we started to suspect that something was leaking memory in the WebLogic framework code. As the leaked object was character array we suspected that the framework was calling toString() method of the return value and the string was never released. To prove this we constructed a small test program which just demonstrated passing large object as arguments and return values in invocations to WebLogic Workshop control from page flow. The memory consumption in WebLogic monitor and console output proved that indeed the toString() method was invoked 1 times in invocation per argument and 2 times per return value. Furthermore by returning empty string in one test and string of several megabytes in other from toString() one could observe exactly matching memory leaking. Manual running of the garbage collector did not release the memory.
To resolve this problem we have tried to alter the Workshop logging configuration in WorkshopLogCfg.xml. Lowering the log level to debug in categories caused much more invocations to the toString() of the arguments. We did not monitor the memory leaking in this test. Raising all the category levels to fatal did not have effect compared to the original settings. Also removing all categories did not have effect on toString() calls.
We have established quite reliably that this leak occurs with our configuration both in development environment (Windows XP) and testing environment (Redhat Linux) both running WebLogic in debug mode. Both of these environments have out of the box log configuration. We have also observed memory leaking in production environment but it has not yet been profiled to see whether the leak is 100% surely due to this same problem.
We have not yet tested this in sp5 nor sp6. Switching service packs is not solution for as in the moment as we are not able to switch the service pack in production environment due to reasons which are out of our control.
We would appreciate confirmation whether this issue is real and any solutions available like configuration modification, patching or switching service pack. Also links to existing articles about this issue would be nice to have.
We can provide the testing code and some screenshots of memory usage via email. You can request it from tommi.laukkanen at xiiris.com.

PS. This is the console out from the test page flow invoking the control:
We have manually thrown and catched exceptions in toString() method to get the stack trace printed to console out.

tlaukkanHi
I did not find any known issues on this. But since you can replicate the issue, could you please contact BEA Support and open a case and have this followed?
Since we may have to do some testing/profiling etc with different service packs with your sample, it would be better to follow up via a support case.
Thanks

Hi,
we're load testing an application using Coherence. It uses a distributed cache, with an web application as the client, and separate cache servers implementing a Cache Store.
We're getting several memory leaks and one area that was reported was a great number of instances for the com.tangosol.coherence.component.util.daemon.queueProcessor.service.DistributedCache$GetRequest class.
Does anybody know what could cause these instances to be left hanging around? I think the Coherence classes ar a symptom of another problem rather than an issue with Coherence itself but it would be useful to know what could cause these objects to be left in the heap.
Thanks
MikeAfter further load testing, our application definitely seems to be leaking Coherence objects.
The classes seem to be com.tangosol.util.Binary &
com.tangosol.coherence.component.util.daemon.queueProcessor.service.DistributedCache$GetRequest.
During testing, the number of Binary objects rose 0 to about 9000 and the number of GetRequest objects rose from 0 to about 3600 in two hours.
The application stores objects in the cache and updates them, the main operation being to add to a very long log string required by the client to these objects, which represent sessions.
Our test keeps a constant number of these objects in the cache during the run, removing the same number it creates after it has ramped up to full load testing.
The application is stateless, it recieves frequent requests to get an object from the cache, work on it and put it back in the cache. The cache also has a cache store to persist the data to a database.
Are there any references to the cache objects that would stop them being garbage collected?
Our whole application is based in a simple stateless reqest/response operation and I cannot see where the huge number of objects is coming from.

Adobe AIR memory leak loading SWFs
I was plagued by a memory leak that would crash my application after a few hours. The application had worked fine in the past but now was having issues and I thought it might have to do with using newer SDK's.
In the end I discovered that if I loaded external swf that had been compiled in debug mode, they would not clear completely on unload and cause a memory leak.
Compiling in release mode fixed the issue. Spent 3 days trying to figure it out.Any chance you can check that out with the latest AIR?
Either way, it sounds like a bug, please report it at http://bugbase.adobe.com/ and then report the bug number here.
If you're able to provide a reproducable case that would really increase the chance that we can do something about it.
Thanks,

Hi All,
OS: Windows Embedded Compact 7 with updates till Feb 2015.
Hardware: AM335x based
Applications running: one serial port application and one tcpclient and tcpserver apps. all are managed (C#) applications
I am facing memory leak issue with our headless device.
When I connect the device to LAN network, memory usage keep increases and after few hour (some times <1 hour, some times 4-5 hour) devices go to hang state due to low memory.
I also tried to run the resource leak detector and found
1. NK.exe heap is increasing
2. on startup : API Handle Count = 4118, DuplicatedHandle - Count : 4,082, Size : 4,082 bytes
After few minutes: APIHandle - Count : 49,172, Size : 49,172 bytes, DuplicatedHandle - Count : 48,810, Size : 48,810 bytes
NK.exe heap increases as available RAM decreases.
our application heap is constant only. please find below memory snapshots taken by devhealth.
1. On device start up after all apps started
2. After 1 hour of device running. - refer attachment
where exactly might be this leak, any Guess?
Thank you...
rakeshHi tomleijen,
Thanks for your suggestions.
Even we tried without any user apps, then also we found ~1 MB increase in NK.exe heap every 30-40 min.
we have 2 images 1. with all WEC7 updates (Till feb 2015) and 2. without any of the WEC7 updates
almost same problem we are facing with both images.

Suspected memory leak in numbers
Dear All!
I am facing a problem in Numbers, which seems to me a memory leak issue.
The original problem occurred when I tried to process a data set consisting of 6 tables of 6 columns by 600-800 rows. A scatterplot with 6 series has been created using 2 selected columns of each table. The "your startup disk is almost full" was first symptom when I realiser that something is going wrong. I traced back using activity monitor that when I edit the spreadsheet the memory fills up rapidly. Once the memory is full the program starts to use up the swap area. I my case I have about 20 GB empty SSD space. After a few hours of work on this table the entire memory and the SSD was filled up.
To check whether the file is corrupted or something else issuing on I made a mock file to test the behaviour. I could produce the same response with a single table of 2 columns and 3000 rows of random numbers and a scatter plot of the this pairs of numbers.
Originally I have faced the problem on a mid 2014 MBP running OS 10.10.3 (i5, 8GB, 128GB SSD) but I have carried out the mock data experiment also on a 2014 MBA OS10.10.2 (i5, 8GB, 128GB SSD) and I have experienced that the memory usage keeps on increasing as I roll up and down in the table, just like on my MBP and in case of the original file. During the few minutes of the test on the MBA the memory usage of the Numbers application indicated in Activity Monitor shoot up from 70Mb to over 1GB and kept on increasing with every operation carried out in numbers, regardless the type of the operation. In this sense there was no difference whether it was rolling the sheet or saving the file.
The extra applications that are installed on both computers: Latex, and Parallels (but non of them were running during the tests)
On my MBP I ran a leak command in terminal for the Numbers and got the following result.

I have searched similar issues on the net and on the community sites but unfortunately could not find any relevant information.
Any help or suggestion would be highly appreciated.Dear Wayne,
Thanks for your suggestions, I will definitely make a bug report. In fact I have already tried it through apples homepage, and I wanted to make a more specific one but to do so you have to become a developer... which would be a really bad joke.
However I did the mock experiment with 700 lines of random data in 2 columns and a scatter plot of the 700 points. The same happens. The memory usage of Numbers went up to 1.63GB... even higher since I have checked.
To answer your questions I have MBP 128 GB SSD of which 20 GB is free, RAM: 8GB
You see... my original problematic dataset consisting of 6 times 500-800 points has been plotted in a fraction of a second, handled as easy as in Excel, LibreOffice or Gnumeric (which are not intended for handling a lot of data; for that purpose I use Matlab or Python). So without any complains or extra effort my data points are plotted beautifully (as lines with no markers to keep the plot clear), but the memory is gradually filled up...
I am not sure it is the right approach to reduce the use of Numbers for very tiny datasets. This would mean that you were unable to make a chart for two years of data of precipitation or temperature or stock value or anything... sounds very unlikely. It sounds like you have a nice car that can go 280 km/h and reach 100 km/h in 4s, with the only the restriction that wheels are designed to fall off at 30 km/h without warning! I don't think that is the case. Would be very unbalanced performance.
Many thanks again. I'll go and make my bug report to get the wheels reinforced .

New Memory Leak Detector released
This week we released an updated version of the Memory Leak Detector. It now features a much improved graphical user interface as well as more powerful ways to track down memory leaks.
The tool is designed to help you find memory leaks in production type environments without causing much overhead. It allows you to attach to a running JRockit process, analyze the heap, and detach, leaving the process running at full speed again.
There is an article on dev2dev which describes the tool in more detail: http://dev2dev.bea.com/pub/a/2005/06/memory_leaks.html
Download the free tool today at: http://dev2dev.bea.com/wljrockit/tools.html
Comments are always welcome here in the forum.
Regards,
/Staffan LarsenFYI, the console ist providing this stack trace in the details window:
java.io.IOException: Unsupported JVM on host 'localhost' at port 7090.
Make sure you are running the correct version of JRockit.

Memory leak while debugging but not in release version
I have an Adobe AIR application that must load and unload multiple external swfs, and it must run for hours.
I had an issue where there was a memory leak. I tried all kinds of fixes, including rolling back SDKs and Adobe Runtime,
but every time I tested in Flashbuilder, the memory would climb, and with each unload a FlexLoader would stay in memory.
Finally I tried creating a release build, and low and behold the memory did not climb. It stayed the same even under stress testing.
So evidently, the memory leak had to do with debug version, and once it was a release version, the leak disappeared.UPDATE: The problem was with the external swfs being loaded into the main application.
If I compiled them in debug, they leaked. In release version they did not. -
After 5 Releases, Why Doesn't Mozilla Care About Memory Leaks?
I'm baffled as to why this is still a problem. After a few hours of use, my memory usage while using Firefox 5.0 is at 1.5GB. I've followed every FAQ, disabled every extension, done everything to stop the memory leaks when using this browser and I'm growing very tired.
I have a Core i7 MacBook Pro with 4GB RAM and Firefox still manages to bring it to it knees. I've been a devoted Firefox user since 2002-3 and I've just about lost my faith in this browser.
Chrome is a featureless, ugly, dinky browser that I hate to use, but it leaves Firefox in its dust performance-wise. Where is the happy medium? I don't get it.
My favorite answer is always, "disable your extensions." Here are the problems with that:
1. Without extensions, Firefox is nothing. I might as well use Chrome.
2. It never seems to help, and when it does a little, it is difficult to figure out which extensions are doing the most damage. Why doesn't Firefox provide a way to look at which extensions are using the most memory?
3. Firefox should lay that smack down on extensions that could potentially leak memory, and yet, nothing. It should at least steal memory back when it gets out of control, regardless of what extension is using it.
4. Mozilla recommends some extensions that are supposed to help reduce memory usage, but none of them work on OS X.
I'm exhausted. I shouldn't have to restart my browser a million times day to get anything done. Where are the real solutions? How do years go by with problems like this still getting worse? Firefox 5 was supposed to be better at handling memory, but it's only gotten worse for me.
When will the madness end? We don't want new features, we want performance! I've always loved this browser, but is it really a surprise that Chrome is taking over?
To sum it up, if your browser is slower than Internet Explorer, you need to hurry up and fix the problem or pack it up and go home.My sentiments exactly!! I have all the exact same complaints and concerns, and I've also tried the solutions provided at no avail.
This the only beef I have with FireFox, but it's a bad one and I've been shopping around for a better browser. Chrome is the best alternative I've found, but it still isn't quite at parity yet.
Please fix this issue or at least make an attempt at it to let your users know it's somewhat of a future priority.
Attached a screen shot of memory usage after 1 hour, and this is the new FF 5 update. -
Pro*c multithreaded application has memory leak
Hi there,
I posted this message a week ago in OCI section, nobody answer me.
I am really curious if my application has a bug or the pro*c has a bug.
Anyone can compile the sample code and test it easily.
I made multithreaded application which queries dynamic SQL, it works.
But the memory leaks when i query the SQL statement.
The more memory leaks, the more i query the SQL statement, even same SQL
statement.
I check it with top, shell command.
My machine is SUN E450, Solaris 8. Oracle 9.2.0.1
Compiler : gcc (GCC) 3.2.2
I changed source code which is from
$(ORACLE_HOME)/precomp/demo/proc/sample10.pc
the sample10 doesn't need to be multithreaded. But i think it has to work
correctly if i changed it to multithreaded application.
the make file and source code will be placed below.
I have to figure out the problem.
Please help

Sample Program 10: Dynamic SQL Method 4
This program connects you to ORACLE using your username and
password, then prompts you for a SQL statement. You can enter
any legal SQL statement. Use regular SQL syntax, not embedded SQL.
Your statement will be processed. If it is a query, the rows
fetched are displayed.
You can enter multi-line statements. The limit is 1023 characters.
This sample program only processes up to MAX_ITEMS bind variables and
MAX_ITEMS select-list items. MAX_ITEMS is #defined to be 40.

sqlprc() is used to extract precision and scale
from the length (select_dp->L).
sqlnul() is used to reset the high-order bit of
the datatype and to check whether the column
is NOT NULL.
CHAR datatypes have length, but zero precision and
scale. The length is defined at CREATE time.
NUMBER datatypes have precision and scale only if
defined at CREATE time. If the column
definition was just NUMBER, the precision
and scale are zero, and you must allocate
the required maximum length.
DATE datatypes return a length of 7 if the default
format is used. This should be increased to
9 to store the actual date character string.
If you use the TO_CHAR function, the maximum
length could be 75, but will probably be less
(you can see the effects of this in SQL*Plus).
ROWID datatype always returns a fixed length of 18 if
coerced to CHAR.
LONG and
LONG RAW datatypes return a length of 0 (zero),
so you need to set a maximum. In this example,
it is 240 characters.

What version of Berkeley DB XML are you using?
What is your operating system and your hardware platform?
For how long have been the application running?
What is your current container size?
What's set for EnvironmentConfig.setThreaded?
Do you know if containers have previously not been closed correctly?
Can you please post the entire error output?
What's the JDK version, 1.4 or 1.5?
Thanks,
Bogdan
