System resources

Recently ugraded to itunes 7.02 and now when i play itunes the music often sticks, (like a cd sticking). It does this randomly and when i look at the system, my processor is at 100% with itunes taking up all the loading - i am running no other software in the background. I have a 3Ghz system with 1Gig of RAM so i cannot believe my system is too slow. I have update all drivers etc to no avail. This never happened with previous Itunes. Anyone any ideas?

My solution: You should get X-plore to delete dirs without messing your phone. Note: Do not delete the dirs that entitled as system, n-gage, and other software name that entitled in the dirs

  • Interactive form takes 10-15 minutes to open and exhausts system resources.

    The version of Livecycle designer am using is 7.1
    The interactive form that I designed is taking like 10-15 minutes to open and while its opening, its taking all the system resources as I see a prompt on the task bar besides time/date  "Virtual Memory Minimum Too Low".
    The tutorial project works fine, the TravelRequest.pdf opens just fine: https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/user-interface-technology/wd%20java/wdjava%20archive/offline%20interactive%20pdf%20form%20using%20download.pdf
    Would installing version 8.0 solve this ?

  • Why the video playback stotter but audio is ok and all system resources are ok as well?

    Hi,
    I'm using Premiere Elements 12 and prepared a project using m2ts files of my sony camera. When I started the project, everything was find, editing easy. Now, some months later I wanted to finish the project on the same laptop ( Intel Cor i5-4200 2,50GHz, 8GB RAM, 64 bit Windwos 8.1, 1TB Hybrid HDD, dual graphic: Intel HD Graphics 4600 and NVIDIA GeForce GT740M). The system resources are not completly used during the playback, maybe 10 - 15% usage, RAM is between 20 and 50% usage, harddrive usage is between 10 and 40% usage. Video data are stored local on the harddrive (not on USB or network).
    When I open the original files in e.g. VLC or Media Player the playback is perfect, no interupts. The playback of rendered elements in Premiere Elements is without interupts as well. Only "native", untouched HD material stotters after a short time I'm working on the project. It's the same for other videos, when I start a new project. It's anoying me because it was the reason why I decided for the SW.
    I deinstalled Premiere Elements completly, used also CCleaner to remove unused registry entries... reinstalled it completly after some restarts... updated to 12.1.0.0 but after an afternoon of installation, the same issue is back.
    Who can help me to fix it? Thanks for your feedback.

    Player version 7.1.6 is a very old version but it should play H264 / AAC videos without issue.

    Hi Sara,
    First of all thank you very much for your prompt responses. Here are my comments to each of your suggestions below, and just to let you know I am using a Farm Admin account.  I
    was able to do this way after we upgraded from SP 2007 to SP 2010 as well.   I would like to mention I'm not a SP expert, just been given the responsibility due to another person handling it just left, so apologize with some of
    my novice questions below?
    1. When I change the Operators to "Contains" or "Not Contains" get generates this error below.
         Error generating in red towards top of the audience page..."One or more values typed on this page are not valid.  Check the text for the indicated fields."
         Error occurred where you enter your "Value"..."Could not resolve the user identity. Please re-enter the account name."
    2. We have a 3-server-tier topology (SPWeb, SPDB, and SPFarm).  Does the updates only apply to where the Central Admin is installed, which is the "SPFarm"?  I checked all
    3 servers, and NONE of the updates (KB2899494, KB2889845, and KB2883055) you'd mentioned are installed.
    3. I'm new to IISRET, I need to be extra cautious of what I run in production, is this safe to run with no problem?  What does it do?  And How do I run it?
    4. I'm also new to viewing the ULS log.  I'd just downloaded a viewer for it.  I'm assuming the only logs I need to be concern with viewing are within the SPAdmin (where Central
    Admin is installed)?  There's so many of them, what should I be looking for exactly?

  • Insufficient system resources exist to complete the requested service

    [I did intend to start this post with a screenshot of the above error when I initiate the transfer from Windows Explorer, but apparently 'Body text cannot contain images or links until we are able to verify your account.' so I will just have to do some typing,
    viz the error dialog says:
     'An unexpected error is keeping you from copying the file. If you continue to receive this error, you can use the error code to search for help with this problem.
    Error 0x800705AA: Insufficient system resources exist to complete the requested service.'
    I get this error pretty much 100% of the time from one particular PC when trying to copy a folder of 10 2GB files to a server with both mirror and parity storage spaces.
    I recently purchased a Thecus W5000 running Windows Storage Server 2012 R2 Essentials. Absent any guidance either way I decided to set up a storage pool across the three 3TB WD Red drives that I have installed in it and to allocate 1.5TB of that space to a
    mirror storage space and the remainder to a parity storage space. Having read some faily dire things about storage spaces, but wanting the resilience provided by those two types of storage space, I decided to run some benchmarking tests before finalising anything.
    To that end I only went as far through the Essentials setup as creating a handful of user accounts before setting up the storage spaces and sharing both of them, with all authenticated users permitted full control. My benchmarking consists of a Take Command
    batch file timing three large directory copies - one with 10 2GB files, one with 10240 10K files and another with a multi-level directory with a variety of files of differing sizes. The first two are completely artificial and the latter is a real world example
    but all are roughly 20GB total size.
    To test various aspects of this I copied the three structures to and then from a partition created on the internal disk (the W5000 has a 500GB SSHD) and to the two storage space partitions. I also created a version of the batch file for use internally which
    did something similar between the internal disk and the two storage space partitions, and another as a control that tested the same process between the two Windows PCs. The internal test ran to successful completion, as did the PC to PC copy and the external
    one from my Windows 8.1 64-bit system (i5 3570K, 16GB RAM, 1TB HD) but when I ran it from my Windows 7 Pro 64-bit gaming rig (i7 2600K, 8GB RAM, 1TB HD) I got a number of failures with this error from Take Command:
    TCC: (Sys) C:\Program Files\bat\thecus_test_pass.btm [31] Insufficient system resources exist to complete the requested service.
    (where line 31 of that batch file is a copy command from local D: to the parity space on the Thecus).
    The error occurs only when copying large files (the 2GB ones already mentioned but some of those in the real world structure that are about 750MB in size) from the Win7 system to the Thecus and only when doing so to the storage space volumes - ie. copying to
    the internal disk works fine, copying from all volumes works fine, copying internally within the Thecus works fine, copying between the Win8 and Win7 machines works fine and initiating the copy as a pull from the server between the same two disks also works
    fine. One aspect of this that surprised me somewhat was just how quickly the copy fails when initiated from Windows Explorer - checking out the details section of the copy dialog I see roughly ten seconds of setting up and then within five seconds after the
    first file transfer is shown as starting the error dialog pops up (as per the image no longer at the top of this post).
    There are no entries in the event log on either machine related to this error and I've had the System Information window of the Sysinternals Process Explorer up and running on both machines whilst testing this, and it shows nothing surprising on either side.
    I've also run with an xperf base active and I can't see anything pertinent in the output from either system.
    Frankly, I am at a loss and have no idea what other troubleshooting steps I should try. The vast majority of the existing advice for this error message seems to relate to Windows 2003 and memory pools - which both the fact that this works from one PC but not
    the other and the SysInfo/xperf output seems to suggest is not the issue. The other thing I've seen mentioned is IRPStackSize, but again if that was the problem I would expect the failure to occur where ever I initiated the large file transfer from.

    Ff it works from the win 8 box, it must be in the win 7 box?
    I'm going to answer this one first because much of the rest of this is not going to be pertinent to the problem at hand. I've been over and over this aspect whilst trying to think this issue through and you are right, except that it only happens when copying
    files to the Thecus and only then when the target is a ReFS partition on a mirror or parity storage space. So the best I can come up with is that it is most likely an issue on the Win7 box that is triggered by something that is happening on the server side,
    but even that is a bit of a stretch. This is why the lack of information from the error message bugs me so much - in order to debug a problem like this you need to know what resource has been exhausted and in which part of the software stack.
    Now that may not be easy to do in a generic way, and since programmers are inherently lazy it is tempting just to return a simple error value and be done with it. However, I've been in the position of doing just that in a commercial product and ended up
    having to go back and improve the error information when that particular message/code was tripped and I was expected to debug the problem! Obviously there is a significant difference between a Microsoft consumer product and a mainframe product that costs many
    times as much and comes with a built in maintenance fee, but the underlying requirement is the same - somebody needs to be able to solve the problem using the information returned. In this case that simply isn't possible.
    You spend your time testing file copies, where I devote most of my time to backup and restore
    I don't really want to be testing file copies - the initial intention was to benchmark the different storage space and file system combinations that I was intending to use but the error whilst doing so has spiralled into a cycle of testing and tweaking that
    really isn't achieving anything. My primary reason for having a NAS at all has always been backup. My current strategy for the two boxes participating in this testing involves having a local drive/partition to hold backups, running a daily incremental file
    copy to that partition which is then immediately copied to a NAS and backing that up with a regular (needs to be at least once per month to be totally secure) full image copy of the local disks that is also copied to the NAS afterwards (hence my fascination
    with copying large files).
    There is a weakness in that strategy because I've never been very good at performing that full image backup regularly enough, so one of the reasons for buying the W5000 was the possibility of making those backups automatic and driven from the server end.
    However, that takes the local backup drives out of the equation and leaves me with the need to backup the NAS, which I don't do with my existing unit because there are (nearly) always copies held elsewhere.
    The other reasons for going with the Thecus were a desire to backup the other machines in the household - I've always dreaded a hard drive failure on my wife's laptop but getting her to perform any kind of housekeeping is nigh on impossible and also to provide
    a file server capability protected by a single set of userids (the existing NAS data is open to all household members). So my goal is backup and restore too ;)
    I meant a different nic on the beast (win 7)
    I should have realised that but obviously wasn't thinking straight. I don't have a spare gigabit NIC to hand (although perhaps even a megabit one might provide an interesting data point) although there is such a card in one of my other (less used) PCs that
    I could cannibalise for testing purposes. Another project for the coming weekend methinks.
    put some limits on it to keep the lawyers happy. 2gb ram, OS loaded on a drive, limit the # of Hard Drives
    That statement got me thinking, because I've never been able to find a definition anywhere of what the restrictions are with WSS 2012 R2 Essential - if I bring up the software license terms on the box itself they are for 2012 Standard!?- and wonder whether
    they'd stop me doing things like adding RAM or changing the processor.
    Even my buddies at wegotserved do not seem to have done any hands on reviews and they get "everything."
    The cynic in me wonders whether that is because Thecus know that they've just shovelled this onto a handful of existing boxes that barely meet the spec. and which simply aren't up to snuff as anything other than a box full of disks.  The Thecus boxes
    look like good value because they include the server OS (the unit cost me roughly 50% more than I could buy Windows Server 2012 R2 Essentials for) but if you can't realise that value then they are just an expensive NAS. 
    if perhaps the algorithms in the Seagate SSHD do not know ReFS?
    I haven't put a ReFS partition on the SSHD, only on the three 3TB WD Reds.
    I will ask my contacts at MS to take a look at this thread, but they stay so busy with v.next I don't know if they will spend many cycles on it
    Perhaps you could ask them if the next version of the OS could do a better job of identifying which resources have been exhausted, by what part of the stack and where in the maze of connectivity that makes up a modern computing environment?? {gd&r}
    Cheers, Steve

  • Firfox uses too much system resource. When idle it uses around 20% CPU and more than 500 mb each of real and virtual memory. Safarai uses 0% CPU and less than 100mb real and less than 200 mb virtual memory.

    It causes my macbook pro 15" to get hot.

    the very problematic plugin-cointainer is the cause of all this! i assume you may be open web page that contain flash right? high system resource slowing your browsing capabilities (click,tab,openpage, slowresponse,etc)
    it is very common problem in windows. you can read it in here under Known Issues->http://www.mozilla.com/en-US/firefox/3.6.15/releasenotes/
    +Some slower machines may see degraded mouse responsiveness when viewing certain Flash videos
    This PROBABLY can happen in your macosx too. Im not sure for that.
    I also try firefox in Ubuntu, and suprisely it smoothly open flash video and playing FB Poker at the same time wo performance degradation .
    i cant give any solution for this unless they came out with better and enhanced performance of firefox for all systems.

  • Verity vspider.exe process never stops and sucks system resources

    I'm running a scheduled task to index a site on a Win2k3 server running CF8. I'm having a problem where the vspider.exe process never stops and sucks up system resources, slowing my whole server down. It actually is doing quite a bit of work... I'm directing the output into a log file, and I'm getting 300 K of information and it seems to be walking the site just fine. But it ends up not finishing the job and running forever. I have to open the task manager to terminate the process and then the server runs better.
    Any ideas?

    I have not found an answer to this problem, though it hasn't been a problem lately. I now send the output of the vspider.exe process to a log file and can check the status of the index job. I index nightly, so if the process is running at anytime, I can look at the results of the index job in my log file. This might give some clues. I have a feeling I had a corrupt index and vspider was choking. Try rebuilding your index from scratch.

  • External Monitor- Does it use substantial system resources?

    Quick question I hope and I apologize if it is answered in another post - I did not find it by searching...
    I use a MacBook Pro with an external cinema display. My Mac is now 3 years old and I can use all the power I can get out of it - for example for video encoding.
    Does having an external monitor connected use system resources that could be used to run my video programs? In other words, would my Mac perform better for these tasks if I disconnect the external monitor?
    Thanks for any feedback.
    Matthew

    No. The MBP will be affected much more by how many applications are running than by whether the external screen is attached or not. Occasional rebooting should help flush out old stubs from inactive programs and other processes. Activity Monitor gives a good view of most everything that is running or idle but maintaining a memory footprint. Generally after a restart you will see the list of things fall to half, depending on how much was running previously and how long since the last restart, etc.

  • [823] [HY000] [Microsoft][ODBC SQL Server Driver][SQL Server]The operating system returned error 1450(Insufficient system resources exist to complete the requested service.) to SQL Server.

    Hi,
    I am facing an issue while loading fresh data into SQL server database.
    we are able to load data into staging area, but while processing stored procedures system face bellow error message :
    [823] [HY000] [Microsoft][ODBC SQL Server Driver][SQL Server]The operating system returned error 1450(Insufficient system resources exist to complete the requested service.) to SQL Server during a write at offset 0x00000243bd0000 in file 'E:\SQLDB\DBName.mdf'.
    Additional messages in the SQL Server error log and system event log may provide more detail. This is a severe system-level error condition that threatens database integrity and must be corrected immediately. Complete a full database consistency check (DBCC
    CHECKDB). This error can be caused by many factors; for more information, see SQL Server Books Online.
    we use windows 2008 R2 with SQL server managment studio 2008.
    Appreciate your suggestion.
    Thanks in advance.
    Best Regards,

    Manorath

    Hi Manorath,
    Based on my research, this issue can be occurred in the following scenarios:
    You are running a DBCC command on a large database. For example, you are running the DBCC CHECKDB statement on the database. At the same time, you run many DML statements on the database.
    You create a database snapshot for a large database. At the same time, you are running many DML statements on the database.
    In these scenarios, the SQL Server service stops responding. The DBCC CHECK statement is never completed, and you receive the error message repeatedly.
    This issue occurs because the sparse file for a database snapshot file has exceeded the file size limitation in NTFS file system. When the operating system error 1450 occurs, SQL Server enters an infinite retry loop.
    To fix this issue, please download and install Cumulative update package 1 for SQL Server 2008 Service Pack 1. Besides, because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous
    SQL Server 2008 fix release. We recommend that you consider applying the most recent fix release that contains this hotfix.

  • Hibernate - Insufficient system resources exist to complete the API (Tecra M4 )

    I just thought that I would pass on my experience with this problem.
    I recently upgraded the memory of my Tecra M4 to 2GB of RAM. Everything was fine except everyonce in a while it would not hibernate. It would suspend to RAM (standby) however. It seemed to happen after the antivirus software kicked in (which I had changed around the same time). I investigated that route but it also happened if I had a lot of programs running. So, a quick google search revealed why almost all laptops ship with only 512MB of RAM.
    There is a problem with Windows releasing the memory in a way which allows it to be written to the hard drive, preventing hibernation and creating the very vague error message "Insufficient system resources exist to complete the API".
    The solution is to contact Microsoft by telephone and ask them for the hotfix from Knowledge Base article #909095. The hotfix is free although the MS website makes it look as though you will have to pay 200 for contacting MS support.
    This seems to have solved my problem!
    Hurray!
    Here is the Knowledge Base article:
    http://support.microsoft.com/?kbid=909095
    Here is the Blog that I first found the solution on:
    http://www.ntwizards.net/2004/10/13/hibernate
    Of course, the one problem with contacting MS support is that I have recieved LOTS of phone calls asking me what I thought of their support... it was pretty good so I don't really mind but I do find it funny that I keep getting called and asked the same questions!

    Hi Kelly

  • Insufficient system resources

    I have a LenovoEMC px4-400r firmware: 4.1.108.32627 running in a domain environment.
    Randomly I'm getting:    Insufficient system resources exist to complete the requested service  
    on clients trying to connect to shares on the NAS.
    After rebooting the NAS everyone is able to access the shares fine until it happens again.
    Anyone have any suggestions?

    Hello robinp1
    Could I have you create a local user(s) via the px4-400r's web interface.  Then try accessing the shares from the same workstations using the local NAS user(s).  This should allow you to test if the issue is being affected by the domain controller(s) or not.
    If the error persists I recommend that you contact support to start a support incident and diagnose the issue further.

    I've investigated this problem in other places, and most of the answers seem to not apply to my case.
    I've looked a this: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4938442
    But I am not using file channels (I don't think...), and I am copying data in chunks of <32MB.
    Here's the relevant code (I realize I don't need to be re-allocating the buffer, that's a legacy from an older version, but I don't think that's the cause.)
    There are usually four threads, 1-4 reports, and 1 scenario, so this loop shouldn't be executing thousands and thousands of times.
    for (int scenario = 0; scenario < scenarios.size(); scenario++)
                        for (int report = 0; report < reportPages.size(); report++)
                             for (LoanThread ln : loanThreads)
                                  BufferedReader br = new BufferedReader(new FileReader(new File(ln.reportPtr.get(
                                            (scenario * reportPages.size()) + report).getFileName())));
                                  br.readLine();//header, throw away
                                  BufferedWriter bw = new BufferedWriter(new FileWriter(formReport.get((scenario * reportPages.size()) + report)
                                            .getFileName(), true));//append
                                  char[] bu = new char[1024 * 1024 * 16];
                                  int charsRead = 0;
                                  while ((charsRead = br.read(bu)) != -1)
                                       bw.write(bu, 0, charsRead);
                                  bw.flush();
                                  bw.close();
                                  br.close();
                                  File f = new File(ln.reportPtr.get((scenario * reportPages.size()) + report).getFileName());
                                  f.delete();
    Any thoughts?Edited by: LizardSF on Jul 29, 2011 8:11 AM

    Added [ code] tags to make the code (more) readable

    1) You can allocate the buffer at the start of the outer loop to save the GC working overtime. You might even be able to move it out of the loops all together but I would need to see more code to be sure of that.+1. Exactly. This is the most important change you must do.
    The other change I would make is to reduce the buffer size. The disk only works in units of 4-16k at a time anyway. You will be surprised how much you can reduce it without affecting performance at all. I would cut it down to no more than a megabyte.
    You could also speed it up probably by a factor of at least two by using InputStreams and OutputStreams and a byte[] buffer, instead of Readers and Writers and char[], as you're only copying the file anyway. Also, those BufferedReaders and Writers are contributing nothing much, in fact nothing after the readLine(), as you are already using a huge buffer. Finally, you should also investigate FileChannel.transferTo() to get even more performance, and no heap memory usage whatsoever. Note that like your copy loop above, you have to check the result it returns and loop until the copy is complete. There are also upper limits on the transferCount that are imposed by the operating system and will cause exceptions, so again don't try to set it too big. A megabyte is again sufficient.
