Extensive (very very very extensive) memory usage of host application with CS extension

Hi!
I tried this only under Photoshop CS5 and InDesign CS5 under Windows 7.
When you open and close CS extension panel, the memory taken by Photoshop (InDesign) increases by 6-30MB!
In case of the simple HelloPhotoshop (HelloInDesign) panel from the examples, compiled in release mode, when you open it and close, - it's about 6-10MB each time you do it. And in case of a more complex panel, which uses AIR, etc. it's about 30MB per one panel close/open.
When I use some panels in 5-10 minutes Photoshop (InDesign) increases its memory pool from 600MB up to 1,2 GB. And more. And this memory is never freed, only until Photoshop (InDesign) shutdown.
I tried freeing all my arrays, killing display objects, etc. - nothing helped. Even a simple HelloPhotoshop (HelloInDesign) that does nothing eats memory.
By the way, InDesign eats memory a lot faster .

James, thank you for the very fast answer! I did various tests on the weekend on my computer and computer of my friend.
And I can say, that Debug flag doesn't affect memory consumption. They still eat memory. My steps to reproduce are as follows:
(Windows 7 32 bit)
Photoshop CS5:
1) set HKEY_CURRENT_USER\Software\Adobe\CSXS2Preferences\PlayerDebugMode to 0
2*) check HKEY_LOCAL_MACHINE\SOFTWARE\Adobe\CSXS2Preferences (just in case)
3) Compile HelloPhotoshop example to ZXP and install via Extension manager
4) restart computer
5) Run Photoshop CS5 - Memory consumption: 100 096 KB
6) Open HelloPhotoshop and close it 10 times
7) Memory consumption: 155 840 - 5,574 MB per one close/open
Maybe a garbage collector is expected to run and free this memory, but it never happened in my case. The memory pool was increasing to 1 GB when I was working with one of my panels - with no documents open in Photoshop
In InDesign I tried the same thing with HelloInDesign ( I had to close the panel completely and then open with Window | Extensions | HelloInDesign)
Memory consumption on start: 118 516
Memory consumption after 10 open/close cycles: 197 516
It's 7,9 MB per one close/open
It's the simpliest panel test. When I'm using AIR libraries the memory usage is increasing a lot faster.

CPU/memory usage of AIR application under Mac 10.4.10

As my AIR application uses a lot of CPU/memory under Mac
(seems better in Windows), I decide to do some basic testing. I
create several applications with different level of complexities.
Below is a table of CPU/memory usage when the application is simply
sitting there. A brief description of the application can be found
in the end of each line.
Here are some results:
[1] Even for an empty application, CPU usage is not zero
(most non-AIR application has 0 CPU usage when doing nothing). Also
the memory usage is huge, comparable to Finder on my computer.
[2] Empty application has 7 threads running.
[3] Indetermined progress bar costs a lot of CPU; and I guess
any other animation costs a lot of CPU too. But if they are
invisible they are fine.
[4] running timer costs CPU.

As to my own application, it's much bigger than these simple
ones. The CPU usually stablizes to 20% and VSIZE is about 1G. There
is no timer running. When I leave the application open for a few
hours, the application will eventually freeze and I have to kill
it.
I am wondering if there are any articles or documents
explaining AIR's CPU/memory usage. And also if AIR is planning to
improve the performance in the next release.

How to capture memory usage for web application

In OATS openscripts, how to capture memory usage for web application? Does it have the exisitng java method that we can call to get the memory data (e.g. peak bytes, private bytes) consumed by web application?

JProbe

Uncontrolled Memory usage in webcenter application.

I have a webcenter application which I use as Consumer Application. This application contains 30 Portlets registered using portlet producers.
All these portlets are again webcenter applications portletized using the Portlet Faces Bridge.
I deploy this consumer application on one of the OC4J containers in application server.
Also, the 30 producers are deployed in another OC4J Container in the same application server.
When I start accessing my consumer application and the page containing any portlet, the heap size of that container starts increasing till it reaches maximum level and then finally hangs up. Also, this heap size does not come down and I am not able to fulfill any further requests.
The container and application logs suggest java.lang.OutOfMemory Error . Heap Space.
Also, the heap size of producer containers is under control. I am not able to understand how to control / release this heap memory.
When I run a minimized version of this consumer application ( having 5 - 10 portlet producers registered) It works pretty fine.
So I think when the number of portlet producer registrations increase, there is this memory leak.
Is there a limit to the number of portlet producers that can be registered in a webcenter consumer application? How can I find out where exactly is the memory leak? How do I bring down the heap size once processing is finished?

Hi vsharma2,
Thanks a lot for your reply.
we have tried all the things mentioned by you. We have also increased the physical memory to the extent we could.
But my main concern is that the memory does not get released. We cannot increase memory to very high levels. It has to stop somewhere.
If we could get a solution whereby we understand how to release the memory consumed by the portlet producers once they have been used, it could solve the problem. Unfortunately, we haven't got any solution in this direction. Also, we have done code optimization, closed everything (whatever we can) in finally block and increased the container Heap size also.
Hope we get something to release the memory consumed by portlets or portlet producers.
Anyway, thanks a lot for your directions.

Kunal

Application with native extension crashes onstart

I've created a flex mobile project with ios native extension(with ad frameworks such as facebook,chartboost ) and linked 3rd party frameworks.
when I start the application,it's crashes.I can't see any logs.is this a problem with linking 3rd party frameworks?
framework didn't work properly with it's directory structure so I followed below link. copied header files .a file to the top of the directory in the 3rd party framework and
removed other folders.

please help

I've been trying to make a Chartboost ANE as well, and I have the same problems as you.
First of all, it's easier to just use the headers and Chartboost static library directly in the Xcode project, instead of the Chartboost.framework. This way, your own .a file will include the Chartboost library, and you don't need to package it in the ANE. The resulting ANE will be smaller as well.
But whichever way you do it, the app will still crash. The error I get is the following:
<Error>: -[__NSCFString isEqualToNumber:]: unrecognized selector sent to instance 0x17802a4e0
This seems to be a problem with newer versions of the Chartboost SDK specifically. So for now I'm still using Chartboost 4.0 in my ANE. Unfortunately it doesn't contain some of the new features I'd like to use.
I've contacted Chartboost support about it. But they say they don't support AIR, and their SDK is working fine when used in a regular native app.
So somehow the combination of Chartboost and AIR is making it crash... If anyone has been able to get it working with the new Chartboost SDK, I would sure like to hear about it!

How to minimize memory usage with VM settings

Using JDK 1.4.2, I am trying to minimize the memory usage of my application.
Our GUI application consumes about ~20MB of heap space during normal operation, but it can easily grow to 50MB in some rare cases (Special feature accessed by user).
We have to be able to run multiple instances (separate process/VMs) of this application on low end Windows PCs.
The applications don't usually run for very long (less than 8 hours).
Here is my problem.
If I set the -Xms=20M -Xmx=64M, it works fine, but the GC is not very aggressive and soon, the application starts using a lot of memory, even if it is not really needed. And it never returns the memory to Windows OS.
So each VM take more memory than really needed, which causes significant swapping on these low end PC (little RAM available).
If I reduce the -Xmx flag, than I run out of memory in the rare cases where I need the full memory.
Ideally, I would like to configure the GC to be more aggressive, i.e. the GC should collect instead of getting additional memory from the OS when possible.
I read a few papers on Sun's web site about HotSpot tunning, but most of them are geared for large servers.
Thanks!
Francois

And you are using the task manager to determine how "much" memory is being used correct?
I suggest that you search out and read the numerous threads on this site that discuss that subject.

Is SL giving maximum priority on memory usage to disk cache???

Pretty much every time I need to work with large files - be it video files, archiving or unarchiving large files, or working with VMWare images - the system quickly runs out of memory and starts swapping profusely. The swap file grows to 2-4 gigabytes pretty quickly, the system becomes unresponsive etc...
I have the latest MacBook Pro 2009 with 4G of RAM, and right after system reboot it shows about 2.8G of free memory, and 0 in swap.
Then I start VMWare, for example, which only uses about 500-600 megabytes of RAM. After some time working with it, the amount of free memory in Mac OS X steadily decreases, and then it starts swapping, and the swap keeps growing... The system becomes slower and slower, but yet, Activity Monitor is still showing that VMWare is using about 500-600 megabytes of memory. At the same time it shows about 2 gigabytes of Active memory, and about 1G of inactive memory, and about 800 megabytes of "wired" memory...
Where the **** did all the memory go??? Did system use it all for disk cache, trying to keep all disk images that VMWare is working with, in it at the expense of physical RAM available to other processes? If it is so - that's VERY silly, and while it may give an appearance of "snappiness" with small amount of simple applications that don't do much, it becomes a MAJOR problem for applications that work with large files - iMovie, VMWare, any other media processing application, cause Mac OS X to start swapping and beachballing, and become unresponsive after certain time of work, while the swap file keeps growing, yet the amount of memory used by those applications shown by Activity Monitor staying around 100-500 megabytes.
I've been working with JES Deinterlacer the other day - trying to convert a 1080i/30fps video into a 720p/60fps one. The file was about 23 gigabytes in size. Besides that I've only had Mail and Safari open. Before I started the deinterlacing process, there was about 1.5G of free memory. After it started, the amount has been going down steadily, until the system started swapping and become unusable after awhile. The deinterlacing process also slowed down significantly (my guess is - again - the system tried to give memory needed by JES Deinterlacer to the disk cache for the file it's been processing). There's no point in caching that file at all - there's 0 chances the application will ever need to jump back to the parts of the file it's already processed! Or to read any parts of the new file it's created!
What's other people's experience working with large files in Snow Leopard? Any Final Cut users? Or iMovie? Does your system exhibit the same behavior? Have you tried monitoring memory usage while you work with any of the applications that work with large files?

Having exactly the same issue. However, I cannot even get VMware to start. It gives me a "could not open paging file" message and never opens. I have also had strange random crashes recently where it seems to run out of memory and then the force quick dialogue opens and usually Safari, Entourage, or Aperture are frozen or paused. Really getting to be a big issue.
I contacted VMware and they looked at all the logs, had me try one change to an internal VM file, but without success. They now are suggesting that based on the logs, it is an OSX paging issue and that I need to do an archive and install!!! No way do I want to do that after just migrating to this new machine and getting everything set up so well!
Need some alternative ideas. Actually hoping 10.6.2 comes out and solves it!

CallManager Report with all Extensions and CSS

I would like to run a report that shows all of my Extensions configured in CallManager and the CSS they belong to. I have yet to find a spot to have that data together. I am working on CallManager8.6 Thank you!

People that don't move much for their jobs have a set phone with a set extension. People who move around a lot have phones with base extensions, and then they log in using extension mobility. We use the CSS to allow them access to outside calling. If they're in a restricted CSS they can't make outside calls. What I'm trying to do is run a report with all of the extensions, the ones on the phones and the ones for extension mobility, and the CSS that those extensions are tied to.

Calcualte Oracle applications memory usage

Is there a way or does anyone have a script for oracle applications memory usage of a period of 30 days??

Hi
By implementing the statspack you can get most of the statistics information including memory usage of apps instance with time intervals. Since there is no GUI performance analysis is complicated with statspack. If you are on 10g a new feature called AWR(automatic workload repository) which gives you statistics and metrics with html format report.
There are some tools to monitor the Oracle applications services like cpu , memory consumption... I prefer to go with your own customization scripts to monitor the instance.
You can get plenty of scripts in the net.
http://www.orafaq.com/scripts/
I have little experience with bmcsoftware which monitors oracle Applicatons. But I am not sure whether it gives statistics for the timeperiod. See the below whitepaper of bmc.

Very high memory usage since upgrading to 3.6.4

Since upgrading 3 days ago FF pretty much runs up to 500mb as a floor and can get up to 800mb of memory. I had this issue with 3.5 but it vanished with 3.6 and was living in bliss as it rarely broke 250 mb.
I haven't added any extensions nor made any other changes. Is anyone else experiencing this?
== This happened ==
Every time Firefox opened
== Upgraded to 3.6.4

Hello everyone.
If you are having problems with RAM/CPU usage, do this:
#run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe-mode] to disable all extensions, themes and plugins. If this fixes your issues, be them with RAM or CPU usage, then you know it's a problem with plugins, themes or extensions. Proceed to number 2. If safe-mode doesn't fix the issues, then read bellow, after this list;
#update all extensions, themes and [https://www.mozilla.com/en-US/plugincheck/ plugins] in your Firefox. If this doesn't solve the issues, proceed to the following number;
#disable all extensions, themes and plugins in your Firefox (not running safe-mode). Being certain that, as in safe-mode, the problems you're having have gone away, enable one plugin at a time. You should be certain that you WANT that plugin to be enabled, so keep your overall number of plugins as low as possible. When you encounter the problems, you know you've found a problematic plugin, so disable it for good. Keep enabling all plugins (except problematic ones) until you've gone through them all.
#enable one extension at a time. Again, be certain that you WANT that extension to be enabled, so keep your overall number of extensions as low as possible. Also, try the theme you want to have installed so see if that is what's causing the problem. When you encounter the problems, you know you've found a problematic extension/theme, so disable it for good. Keep enabling all your extensions (except problematic ones) until you've gone through them all;
#you're done! You've fixed your problems with problematic add-ons. If you want to keep using those problematic add-ons, please contant their author for support.
Ok, if disabling all extensions and plugins through safe-mode didn't work to bring Firefox's CPU and RAM usage to good levels, then you have different issue. The most likely scenario is that you have a third party software running on your computer that is messing with Firefox. Do as follows:
#try reinstalling Firefox. No data will be lost. You can get the latest version for free at [http://www.getfirefox.com/ getfirefox.com]. If that doesn't fix the problem, proceed;
#do a virus/malware check on your computer. If this doesn't fix it, proceed;
#disable all software running in the background that you don't want to have running in the background (in windows, this is done by pressing WINDOWS+R in your keyboard, typing "msconfig" (without the commas) and pressing enter. Now, under the "Startup" tab, you can uncheck the software you don't want, and reboot your system for changes to take effect. If you're unsure of what software you want running, ask someone with more experience). If this doesn't fix your issues with Firefox, proceed;
#check your firewall/antivirus/security suite for enabled functions/features that you don't want and/or may be conflicting with Firefox. You'll find that these features are most likely tied to Internet Security features, such as link scanners or URL checkers and the like. If you're not sure they are conflicting with Firefox, simply try to disable them to see whether or not that's true. As long as you don't browse the web with your antivirus completely off and your firewall completely turned off, there should be no problems. If this doesn't solve the issues, proceed to the following number;
#check your operating system security options, mainly advanced options that are not configured by default. While it's very unlikely that this may be the cause of the problem (after all, it's the last item on the list), it's remotely possible. If this doesn't work, proceed to the following point;
#update your modem/router software. There have been some reports that some modem/router software may cause Firefox and other browsers to loose performance and/or stability. If updating doesn't fix your issue, try other versions of the software, if possible. If you need support with this, contact your modem/router manufacturer. If this doesn't help, proceed;
#clean up your OS registry, using appropriate software. Make sure you've followed my instructions correctly, but if this all doesn't work, [http://support.mozilla.com/en-US/kb/Managing+profiles create a new Firefox profile] (this can be temporary, of course) and see if the issues persist. Report here the results, so we can help you further.

Very high memory usage with Yahoo Mail

After using Yahoo Mail for an hour or so my memory usage increases to a very high level.
Just now, after reading and deleting about 50 e-mails (newsletters etc.) I noticed Firefox 17 running slowly and checked the memory usage in Windows Task Manager (I am using XP) and it was 1.2 Gb. My older laptop only has 2 Gb of RAM. Yahoo Mail was the only thing open at the time.
I never notice this problem with Gmail which I mainly use. However I use Yahoo Mail for quite a few newsletters etc. that are less important and which I only check once a week or so.
I found the following bug report about 3 years old which almost exactly describes my problem.
https://bugzilla.mozilla.org/show_bug.cgi?id=506771
But this report involves a much earlier Firefox version, and at the end it seems to say that the problem was fixed. However it well describes my current issue with Firefox 17, especially the continual increase in memory while using the up/down arrow keys to scroll through Yahoo e-mails.
Is this normal to have to shut down and reopen Firefox every hour or so to clean out the memory? For some reason I only notice this when using Yahoo Mail. After using many other sites and having multiple tabs open for several hours I rarely reach that kind of memory usage. About the highest I've seen with other sites after a couple of hours is 600 Kb which is roughly when I start notice slower response times.

Very High Memory Usage

It never happened before and today it overloaded my PC so i had to force restart.
I use 2 keyword research applications. They start to shoot up to almost 600MB of RAM when i am researching keywords. When i minimize program after research, the memory usage drops to 32MB. When i restore window back, these 32MBs turn back into 600MB.
I tried downgrading Adobe Air to version 2.0.4 and that didn't help. Upgrading to the newest version didn't help.
What is the problem?

Hi Boris,
The memory usage is very dependent on the application and how it handles it's resources. Have you contacted the developers of the two applications to see if your findings are consistent with their testing? You mentioned that the memory footprint is the same between 2.0.2 and 2.5, do you know if it increased after 1.5.3?
Having the memory usage drop to a fraction of it's normal size when minimized is consistent with normal Windows behavior.
Thanks,
Chris

Very high memory usage..possible memory leak? Solaris 10 8/07 x64

Hi,
I noticed yesterday that my machine was becoming increasingly slow, where once it was pretty snappy. It's a Compaq SR5250NX with 1GB of RAM. Upon checking vmstat, I noticed that the "Free" column was ~191MB. Now, the only applications I had open were FireFox 2.0.11, GAIM, and StarOffice. I closed all of them, and the number reported in the "Free" column became approximately 195MB. "Pagefile" was about 5.5x that size. There were no other applications running and it's a single user machine, so I was the only one logged in. System uptime: 9 days.
I logged out, logged back in, to see if that had an affect. It did not. Rebooted and obviously, that fixed it. Now with only FireFox, GAIM, and a terminal open, vmstat reports "Free" as ~450MB. I've noticed if I run vmstat every few seconds, the "Free" total keeps going down. Example:

Any tips, tricks, advice, on which way to go with this?
Thanks!

In any event, we can see that FireFox is sucking up 145MB (??!?!!? crazy...) XSun, 200MB, and java 190MB. I'm running Java Desktop System (Release 3) so I assume that is what accounts for the the high memory usage RE: java process. But, XSun, 200MB?
Is this normal and I just need to toss another gig in, or what?
Thanks

Problem with Firefox and very heavy memory usage

For several releases now, Firefox has been particularly heavy on memory usage. With its most recent version, with a single browser instance and only one tab, Firefox consumes more memory that any other application running on my Windows PC. The memory footprint grows significantly as I open additional tabs, getting to almost 1GB when there are 7 or 8 tabs open. This is as true with no extensions or pluggins, and with the usual set, (firebug, fire cookie, fireshot, XMarks). Right now, with 2 tabs, the memory is at 217,128K and climbing, CPU is between 0.2 and 1.5%.
I have read dozens of threads providing "helpful" suggestions, and tried any that seem reasonable. But like most others who experience Firebug's memory problems, none address the issue.
Firefox is an excellent tool for web developers, and I rely on it heavily, but have now resorted to using Chrome as the default and only open Firefox when I must, in order to test or debug a page.
Is there no hope of resolving this problem? So far, from responses to other similar threads, the response has been to deny any responsibility and blame extensions and/or pluggins. This is not helpful and not accurate. Will Firefox accept ownership for this problem and try to address it properly, or must we continue to suffer for your failings?

55%, it's still 1.6Gb....there shouldn't be a problem scanning something that it says will take up 300Mb, then actually only takes up 70Mb.
And not wrong, it obviously isn't releasing the memory when other applications need it because it doesn't, I have to close PS before it will release it. Yes, it probably is supposed to release it, but it isn't.
Thank you for your answer (even if it did appear to me to be a bit rude/shouty, perhaps something more polite than "Wrong!" next time) but I'm sitting at my computer, and I can see what is using how much memory and when, you can't.

Very low on system memory warning with plenty of memory left

Hi,
I am using Premiere Elements 7 on Windows XP, AMD 3GHz dual core with 4GB memory. I create DVDs based on AVCHD files from a Canon HF100, almost no editing, 1 hour of DVD content (8 GB worth of AVCHD files) . I have done this with the same configuration in the past without problems, but lately Premiere has been very unstable, either crashing outright or giving me the following warning:
Adobe Premiere Elements is running very low on system memory. Please save your project and proceed with caution.
When I try to burn a DVD, this warning is always shows within minutes, followed by a transcoding error. I tried everything to free up more space, nothing else significant is running on my machine, and I have exited most other background processes. When the above warning is shown, physical memory consumption is is reported as following:
Commit Charge: 1.8 GB
Premiere Elements process: 1.1 GB
Free memory: 1.5 GB
I also have virtual memory set to 8GB. Premiere scratch directories are on a disk with 500GB free space. I uninstalled and reinstalled Premiere, but no improvement.
Other relevant software on my machine, some of it installed after I had my last successful DVD burn:
Norton 360 2010 (Disabled Firewall and Autoprotect)
Adobe Web Premium CS3
Adobe Lightroom 2.5
Copernic Desktop Search (Disabled)
A number of free video tools, like HandBrake, AutoGK, AVISynth, VobSub, DVD Decrypter, Xvid
Tivo Desktop (Disabled)
iTunes (Disabled)
Could there be any side effect from the other software? Any potential hardware problems I should investigate? Everything else works perfectly, including the other Adobe products.
I very much appreciate your help, Premiere is unusable at the moment and I have some DVDs I desperately want to create.
Thanks,
Alex

Have you rendered your timeline?
If you're sceneline mode, switch to timeline mode. Is there a red line above your clips? If so, press Enter and let the program render your timeline (the red line will turn green).
This should greatly improve your program's stability and performance.
Also, ensure that the disc where you are storing your video files is formatted NTFS and not FAT32 (as they are when they come from the factory). FAT32 drives have a file size limit that can choke video work.
And, if this 500 gig drive is not your C drive, ensure that your C drive also has at least 30-50 gigs of free space, freshly defragmented and with its temp files regularly cleared.
