Incorrect memory usage display

as i was uploading songs onto my ipod mini from my windows computer, itunes suddenly felt like erasing my songs from my ipod, keeping in mind that i do not have auto-update turned on. Yet i could have easily re-uploaded my songs, so this was not a problem. What worried me is that my ipod is registering a 1.62 GB usage, the equivalent to the 500 songs i previously had, yet it is completely empty of songs. What happened?

If you were using the iPod in Disk Mode...
iTunes or Operating System says Disk is full, but Doesn’t Appear Full
Otherwise, try Restoring your iPod.

  • Activity Monitor Indicates 16+TB Memory Usage !

    Has anyone ever seen an application's memory usage displayed in the Activity Monitor as 'Terabytes?' I recently noticed that Photoshop CS3 was using [get this] '16,777,216.00TB' of Real Memory. I spoke with both Adobe & Apple, and neither has any reports of anything like this. Weird!

    Did restart, but haven't had a chance to run PS yet. I did repair permissions via Disk Utility and there were quite a few corrections. Whether that had anything to do with it remains to be seen. I did read once that incorrect permissions [set incorrectly by installers] can cause a host of application-related issues [such as app crashes and the inability to launch them]. Other app memory usage looks normal.

  • Display memory usage-help for parameters

    hi everyone ,
    i want to display the memory usage(shared memory+heap) while compiling the t code in foot path,
    plz help me for this issue

    Hey Arun,
    RZ20 SAP CCMS Monitor Templates->Performance Overview->Memory Management
    You can see all the information which you are looking for.
    But to make it web enabled you need to call some BAPI through java and store it DB. If you have any Java programmer let me know I will send you the list of BAPI.
    Use the DB data and draw a graph. Using that data you can study the performance over a period and start tuning your system.
    Thanks & Regards

  • IPad with retina displaying wrong memory usage amount

    I am using a 4th gen iPad, (iPad with retina and lighting port) and I have the 32gb with cellular version. Right now, my cellular is not active, but I'm with Telus, not sure if that matters. I'm running iOS 7.0.4. A few weeks ago, I realized I was running low on space, so I deleted a bunch of apps on my iPad, deleted tons of photos, etc. It said I had about 3gb of space available before I did that, but after, it only said I had about 6gb left. I have added up the memory usage of each app, and it only comes to about 13gb used, yet the usage says I have used up 21gb, and I only have about 6.5gb free. Even though I should have like 20gb free. I have turned my iPad on an off a few times with no change, I have restarted my iPad by holding down the home and power buttons, and still nothing. This is concerning me as to where this extra 8-9gb is being taken up. I should have a max capacity of 28gb, but my system says I am using up 21gb with 6gb free. Where as my math by adding up each apps usage only adds up to about 13gb or less. I have iTunes Match turned on, by my music app shows only 266mb used.
    Anybody else having this problem? Does anyone have a solution?

    Just a note: you may find the memory clock weird, but I have overclocked it to its nominal capacity (the memory chips are 4 ns).

  • Problem with JTree and memory usage

    I have problem with the JTree when memory usage is over the phisical memory( I have 512MB).
    I use JTree to display very large data about structure organization of big company. It is working fine until memory usage is over the phisical memory - then some of nodes are not visible.
    I hope somebody has an idea about this problem.

    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.

  • Tracking Memory usage on iOS using the Stats class

    I've been checking memory usage on an app I'm developing for iOS using the Stats class https://github.com/mrdoob/Hi-ReS-Stats ( http://help.adobe.com/en_US/as3/mobile/WS4bebcd66a74275c3-315cd077124319488fd-7fff.html#WS 948100b6829bd5a61637f0a412623fd0543-8000).
    I added the Stats class to my project and redeployed and, yikes, memory usage reported in Stats creeps up (pretty slowly) even when there's nothing happening in the app (just showing a loaded bitmap).
    To try and track down the issue I created a project with a test class that extends Sprite with just this single call in the constructor :-
    addChild( new Stats() );
    I deployed it to the device to check that it didn't gobble any memory.
    But I was Suprised to watch the memory usage creep up and up (to approx 5) before some garbage collection kicked in and takes memory back down. I left it running and then it crept up again to over 7.5 this time before being kicked back down to just below 3.
    So 2 related questions that I'd appreciate any feedback/observations/thoughts on :-
    1 - Is this normal (i.e. memory creeping up when there's nothing other than Stats in the project) ?
    2 - What is the best way to monitor memory usage within an app ? Is Stats good enough - is Stats itself causing the memory usage ?
    All the best guys !

    Also see thread (http://forums.adobe.com/message/4280020#4280020)
    My conclusions are :-
    - If you run an app and leave it idle, memory usage gradually creeps up (presumably as memory is being used to perform calcs/refresh the display etc)
    - Periodically the garbage collection kicks in and memory is brought back down
    - This cycle could be in excess of 5 mins
    Run with your real app and memory will increase and be released much more rapidly/regularly.
    - It's probably worth performing initial checks by running on your desktop to iron out any initial problems

  • 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.

  • High disk usage/high memory usage.

    i keep getting high memory usage and high disk usage in ps cs6.
    its slow when i open a file. how can i solve this problem.
    thank you.
    philip.

    Not to put too fine a point on it, but more than what?  More RAM is almost always better, but you haven't answered most of the questions posed here.  The answer might be different if you have 2 GB of RAM or 32 GB of RAM already.  A 9 megapixel document could get rather large with a lot of layers, but again you've neglected to give any hard info about its size.
    Regarding your video card, that's a bit of a judgment call you need to make.  For Photoshop CS6 I currently advise people to try to get a video card that gets a score of 1000 or better on this benchmark:  http://www.videocardbenchmark.net/high_end_gpus.html
    Video card speed will matter when you're editing those 3D components and video card VRAM will also matter, but possibly even more importantly your GeForce 320 is a bit old, and nVidia may just not be doing their best driver work for it any more. 
    Everything in general will run more smoothly with a powerful modern video card.  I like to recommend a VisionTek ATI Radeon HD 7750 - or if the computer power supply and your budget allow, the even more powerful 7850.  VisionTek does a very good job with their hardware, IMO, and it comes with a lifetime guarantee. 
    Keep in mind that if you switch from nVidia to ATI or vice versa, you should carefully sweep your system to ensure all files from the old card are removed, then visit the web site of the new card's maker and download/install their latest display driver release.
    Best of luck.

  • Network stream fxp excess memory usage and poor performance

    I'm trying to stream some datas à highspeed rate (3 channels à 1Mbytes/s) from my 9030 to my windows host. Because i don't need to use data on the rt side, i choose to forward FXP <+-,24,5> to my host throug a network stream.
    To avoid data loose i choose to use a wide buffer of 6000000 with this buffer my memory usage grow from 441mo to 672Mo and my rio is unable to stream the data. 
    With sgl or double, memory usage is 441 to 491Mo and datas can be streamed continusly.
    Anyone have encoutered this problem?

    SQL Developer is java based and relies on the jvm's memory management.
    I'm not aware of any memory leaks as such, but memory tends not to be returned to the system.
    Queries which return large return sets tend to use a lot of memory (SQL Developer has to build a java table containing all the results for display).
    You can restrict the maximum memory allocated by modifying settings in in <sqldeveloper>\ide\bin\ide.conf
    The defaults are -
    AddVMOption -Xmx640M
    AddVMOption -Xms128M

    i've read i can disable the kernel modules that i don't need to improve the memory usage.
    which modules i can disable without "kill my system"?. i don't want SATA, DVD, bluray, infrared, floppys, bluetooth, usb3.0, 3d video card, dial-up-integrated modem, ntfs, 'cause mi old is so old. i want it only for the university.
    thanks in advantage for the tips, and sorry if someone can't understand very well that i wanna tell you, english isn't my "mother languaje".

    thanks for the answers. yes, i have a 1 gb of swap.
    i think i can reduce the memory usage of the system if i dissable the kernel modules that i don't use. but, the question is: what modules is safe to disable to get it?
    thanks in advantage

  • About the limitation of memory usage of Illustrator.

    Please tell us about the behavior of the illustrator CS5/CS6 when memory usage of illustrator is too many.
    The memory usage of Illustrator is increased, I think the application operates as follow.
    - Warning display (e.g.:Illustrator can not preview)
    - Illustrator stalls
    1.Such as case, Is there memory usage limit?
    2.In the case of memory usage of Illustrator exceed maximum size, how Illustrator works?
      Is there a specification?
    3.Is there the function of the memory auto-release in Illustrator?When the function work?

    Thanks.  Finally found where it is and turned off all alerts.  Verizon doesn't make it easy to find where it is located.  Appreciate the help.

  • Itunes 11.1.5.5 memory usage windows 7

    I have a very large iTunes library.  Lots of music, movies, tv shows, etc.  It links to the AppleTV in the media room.
    Lately, around two updates ago, memory usage of iTunes went all wonky.  When first started it uses around 100k. Within a few hours it's over 1.5gb and stops working.  It happens faster if we're using AppleTV.
    It's becoming really, really frustrating, to the point where my wife has just quit using it because when iTunes locks up AppleTV stops working.
    I've seen this issue crop up elsewhere on the forums, but have yet to see a real solution.
    Turning off album view or poster view makes no different.  This happenes no matter what screen iTunes is displaying.
    MH

    Thanks for your help. Started itunes in safe mode and it still closed down after approx an hour. There are no add-ons or plug-ins installed. I had previously checked the safe mode and also uninstalled all apple software in the order that one of the help pages indicated. Then redownloaded and installed itunes - made no difference.
    After opening itunes it works fine with no problems - what baffles me is that it then stops working even if the software is not active at the time.

  • SQL Memory Usage

    Hello
    I am updating some items with the DTW. i am updating 9000 items. I have made 9 files of 1000 records, i am just updating the picturname field. When i start to upload the files the SQL Memory usage starts to grow more and more. When i try to upload the third file the memory has grown too much, and the DTW says the file update ok but it doesnt update the database. So i need to restart the SQL service (mssqlserver) and do it again. Some times it doesnt work so i need to restart the server.
    Any ideas??

    hi,
    Check this information abt DI API Memory Consumption in WIKI SDK FAQ's.
    https://www.sdn.sap.com/irj/scn/wiki?path=/display/b1/faq_sdk
    DI API
    Memory consumption
    New connection mechanism in 2007 vs. classical
    1. In the old method the DI API was loaded into the same process with the Add-On and was an "actual part" of it, so calls to the DI-API were very quick and direct
    2. In the new method there is one common DI-API which is part of the Core B1. All the Add-Ons will use the same DI-API IF (!!!) they work in the new method. The calls to the DI-API have now to "go between" two processes. This means that they go through more processing and although it's all in the same machine and no actual communication (i.e., network traffic) is actually happening, the system's CPU and memory are "working harder".
    The impact is extremely small on an individual call level, but for an Add-On that makes a large amount of calls this difference accumulates...
    There is no huge additional CPU or Memory consumption. Most of the impact is on the Response Time level. Some of it is CPU consumption and some of it is Context Switch waiting.
    3. This trade-off between Memory consumption and Response Time is actually another reason why R&D thought it's a good idea to leave the new method to be optional based on a decision from the developer.

  • 0.5 MB program has 832 MB memory usage even before it is run

    I just uninstalled and re-installed LabVIEW 2011. I was hoping this would do something to lower the memory footprint. Alas, it did not make any difference. This is what I see:
    - When I launch LabVIEW, it uses 94 MB even before I have opened a single VI, i.e. only the front end uses this much memory.
    - When I open the VI (the size of the .vi file is 549 KB), memory usage goes up to 836.4 MB. This is before I have even run the program.
    - Finally, when I run the program, memory usage jumps to 1.17 GB.
    I find this memory usage grotesquely high. Can anyone please shed some light on what can be done? I have uploaded the VI. It's a rather simple VI.
    Thanks,
    Neil

    1) If I understand correctly, what you are saying is that when I open the VI, the data structures associated with the intensity charts and waveform graphs are initialized to default values (e.g. 0), so there is memory usage even before the program is run and anything displayed, right?
    Yes, a huge array still takes a lot of memory, even though it compresses well for storage inside the VI. Once the VI is ready to run, these arrays need to be allocated in memory.

    2) Is there an alternative to using the value property node that doesn't duplicate the memory content? (e.g. something like pointer or reference in C++?)
    One possiblity are data value references. You can open a DVR and fill it inside the subVI, then extract slices later as needed. If done properly, you can also keep the 2D data in a shift register (yes, please learn about them!).

    4) Regarding the clearing of the indicators, could you please tell me how to do that, without removing the color ramp settings?
    The color ramps can be set programmatically using property nodes based on array min&max and you can assign colors for the ramp values at will.

    5) You are correct that I am displaying 4000x2000 array data in an intensity graph with 400x200 pixels. But then I change the min/max of the charts/graphs to zoom into the region of interest; I can identify the region of interest only after displaying the full 4000x2000 array of data. I don't know if there is a way around this.
    Do you really need to show the 2D data in three different transforms? Maybe one intensity graph is sufficient. You can apply the other transforms on the extracted slices with <<1% of the computing effort. What is the range and resolution of your data? Do you really need DBL or is a smaller representation sufficient (SGL, I16, etc). From looking at the subVI, the raw data is U16. The subVI also involves a coercion to DBL, requireing another data copy in memory. When running, make absolutely sure that the subVI front panel is closed, else additional memory is used for the huge array indicator there. For better performance, you might want to flatten the subVI to the main diagram or at least inline it.

    6) Yes, I use the continuous run mode instead of a toplevel while loop. Is there a disadvantage to doing that?
    As Samuel Goldwyn ("A hospital is no place to be sick") might have said: "Run continuously is no way to run a VI"
    Run continuously is a debugging tool and has no place in typical use. What it basically does is restart the VI automatically whenever it completes, and as fast as the CPU allows. It is mostly useful to quickly test subVIs that don't have a toplevel loop and play with inputs to verify results. Any toplevel VI needs a while loop surrounding the core code. Period!
    So, my suggested plan of action would be:
    Use a while loop around your toplevel code
    Decide on the minimal representation needed to faithfully show the data.
    Keep a single copy of the 2D array in a DVR
    You optionally might want to undersample the data for display according to the pixel resolution and use other means of zooming and panning. For zooming, you could extract a differently sampled small array subset and adjust x0 and dx of the axes accordingly.
    Use a single 2D graph (if you need to see the various transforms, add a ring selector and transform the 2D array in place. Never show more than one intensity graph.
    See how far you get.

  • Flash player memory usage Safari 5.1.7;  OS X 10.7.4

    I've heard quite a bit about the relationship between Apple and Flash but since getting my laptop I've noticed that the two aren't getting along. While browsing the web (±4 tabs, 2 with music playing on youtube) I realised that my brand spanking new MBP was freezing up on me. I checked the activity monitor and noticed that I only had 18mb of RAM free, after checking the processes I found flash player was the culprit.
    It was using a whopping 900+mb of RAM which is almost a fourth of the available memory. I closed the rest of my applications and freed up another 300mb but within about 5 minutes flash player had eaten up all of that as well. I'm not sure if this is considered a memory leak but I am pretty sure that this is not normal.
    Any suggestions? My friend who uses Firefox also said he was facing the same problem, so I don't know if switching browser will help.

    I am having difficulty reproducing my trader desktop result using the blazeds sample application.  So either I was mistaken, or perhaps I have a newer version than what I tested with originally.
    I can reproduce the issue with our Flex application on the latest release of the flash player.  Using chrome and 11.3.300.262 there is a noted increase in memory utilization of between 50-100MB/hour.  This is a real time messaging dashboard application that constantly updates prices displayed in charts and tickers using Adobe messaging.
    On 11.2.2.144 on the same installation of chrome this application reaches an initial memory utilization and then stays at or close to that memory level indefinitely - though memory usage will increase slightly as more and more data points are added to the charts displayed - nothing like 50-100MB/hour.
    I would need to give your people access to our application as it's not publicly accessible.  So again, please contact me - flashbug at vanderberg.fastmail.fm to arrange those details.
