[10.1.2] Protected Mode causing 100% CPU Usage/Extra Processes on Win XP 32-bit?

Hello,
I'm not 100% sure if the two are related, but I have a client who was seeing 100% CPU usage using Adobe Acrobat Reader X 10.1.2 on Windows XP 32-bit and Firefox 11. The acrord32.exe process would hang around after closing the main window and eventually leading to tons of processes and his CPU at 100% use. I believe disabling Protected Mode may have solved this issue. I didn't see it documented anywhere so I figure I'd post about it here and see if anyone else was seeing this resolved as well.

I noticed 'only' 50 % CPU usage. Not during Reader usage with ~ 20 %, but it started after closing main window.
Two instances of acrord32.exe were created - the moment pdf was opened - of which one was using zero CPU.
After opening another pdf, 2 more processes were created, so 4 in total. Have seen 2 of them using 100 %.
Issue is easily recreated.
This is all in 10.1.3, no fix from Adobe, only THE fix from you: turning of Protected Mode!
After which now only one proces is created, with 1 to 3 pdf documents opened at same time.
This instance is then nicely shutdown after the last pfd is closed.

  • Recently FireFox often has been causing 100% CPU usage and locks up until it finishes the process (various ones). Clearing cookies/cache didn't help. Any ideas?

    Windows 2000 SP4, 1g RAM, Firefox 9.0.1
    We keep IE6 and Firefox open simultaneously for 2 different mail accounts. Firefox was always much faster even with 3 or 4 tabs open, but for the past couple of weeks when trying to update a screen the CPU suddenly goes to 100% usage and of course nothing will move until the particular process is finished. Closing one or more tabs does not help. If I close Firefox completely with Task Manager CPU usage goes back down to nil. After restarting Firefox CPU usage may or may not go back up depending upon whether it tries to continue the previous task that was locking it up.
    It did not do this with Firefox 3.6 but then again it didn't happen immediately after updating to 9.0.1 either.

    100% CPU usage occurred most often toward the end of the working day when busy trying to print on-line postage. We don't have any memory-consuming plugins but according to the knowledge base articles Firefox memory usage can gradually increase during the day even if you do nothing. It seems that may be the problem so we close and restart Firefox more often now as that usually fixes the problem. However, if we get stuck on a particular website update that causes the CPU to to go 100%, we can always start Firefox without previous tabs so the update will stop, or simply use a different browser until we have time to let the computer play games with itself.
    So our workaround of restarting Firefox turns out to be the final solution (until we find something better - will post it if we do). Vic

  • Copying from USB NTFS device with Dolphin (KDE) causes 100% CPU usage

    I am copying +/- 30 GB of Music files (flac) from my external USB HDD which is formatted as NTFS.
    I have installed ntfs-3g and am experiencing near 100% CPU usage. What's wrong?
    Additional info: I am using KDE and initiated the copying through dolphin. KDE's system monitor only shows CPU usage near 100%, but no processes in the process view could be responsable.
    Thanks!

    What mount options are used for that ntfs drive?
    Edit: There are many similar threads but I couldn't find a solution other than trying out some kernel and cpufrequtils fun.

  • Spreadsheet functions causing 100% CPU usage

    Running ColdFusion Enterprise 9,0,0,251028 with JVM 1.6.0_14 on a Windows 2003 server.   I am finding that when using <cfspreadsheet> and the spreadsheet functions to build a spreadsheet the server CPU maxes out at 100% while the spreadsheet object is being built.   The spreadsheet is not overly large or complex:  10-15 columns and 400-500 rows.   This behavior is consistent - it happens every time, even when building a simple spreadsheet with 1 column and a few rows.  Is anyone else experiencing this?    Is it a known problem with a fix?  Thank you.

    I was able to root cause the excessive CPU usage to a single-CPU virtual machine.  When I ran the same code on dual-CPU virtual machines the CPU usage went to 50-60% but never reached 100% and stayed there as it does on the single-CPU virtual machine.   So there appears to be an issue with JRun and Apache POI on single-CPU machines.  I simply had my system administrator add another CPU to the virtual machine and the problem no longer occurs.

  • Small Acrobat file causes 100% cpu usage with v. 7.09

    Using Acrobat professional 7.09
    I have a small acrobat file (94k) that causes my cpu to peg at 100% I used acrobat professional to convert an eps file to a pdf file. Is there a general known issue that could be causing this?

    > Looking at the plot, you might want to consider trying to use a vector graphic in the future. It looks like a plot that you may have created in MATLAB or such. In that case, why not just print to the PDF.
    I used matplotlib, which can generate png, eps, svg, or even pdf files. The pdf in question was converted by acrobat from eps, which has worked well for me in the past. I wish acrobat pro 7 could handle svg.

  • SQL query against ConfigMgr DB causing 100% cpu usage on SQL server throughout day

    Hi, I am hoping someone here may have an idea of what I can do to resolve this as I am not much of a SQL guy. Here is what I know. Throughout the day, monday-friday, my ConfigMgr SQL server sits at 98-100% processor usage.
    Using the following query I have narrowed down the culprit of the high cpu usage throughout the day:
    SELECT p.spid, p.status, p.hostname, p.loginame, p.cpu, r.start_time, r.command,
    p.program_name, text
    FROM sys.dm_exec_requests AS r,
    master.dbo.sysprocesses AS p
    CROSS APPLY sys.dm_exec_sql_text(p.sql_handle)
    WHERE p.status NOT IN ('sleeping', 'background')
    AND r.session_id = p.spid
    Even though my knowledge of SQL is light, I believe the following output clearly defines the thread responsible for the high cpu usage. This "program_name" is present throughout the day and as long as its there, cpu usage remains at or near 100%:
    The text output of the above culprit is as follows (sorry this is long):

    If anyone has any experience with this issue or anything similar and might be able to point me in the right direction, any responses would be greatly appreciated. Thanks for reading!

    Normally, this summary job every few mins which only summarize last few mins sending history. If the job was not running for long time, the first time, this sproc will summarize a lot more data than normal. So it could fail which will make things worse and
    worse over time.
    If sending summary data is not a big concern here, you can manually insert a dummy row with most recent time as Summarizationtime, so that, when summary job kicks in next time, it will only summary short interval data.
    DrsSendHistory is that the table records every sending on every group. This table is one of the key of replication logic. For your environment, on primary site, it could have up to 24(hrs) * 60 (mins) / 2 (sync interval) * 36(secondary sites) records per
    day for Secondary_Site_Replication_Configuration group and 24 * 60 / 5 * 22 records for Secondary Site Data.

    Hi Umair,
    Thank you for the reply. My plan was to go ahead with your suggestions but what I tried first was to get my VM guy to give the SQL server access to more CPU resources. We had already configured it with what would have seemed to be plenty, as per Microsoft's
    sizing requirements, but I figured it couldn't hurt to rule out - he gave the SQL server access to a huge portion of the host processing power and since then CPU usage on the server has NOT been an issue.
    It would appear that the large amounts of secondary sites we have just simply put a lot of stress on the SQL server with out of the box replication settings. Since the entire VM host is for System Center only, and our other System Center servers are using
    very little resources, this solution has ended up being valid.
    Thanks again for everyone's help with this.

  • Large-scale swf causes 100% CPU usage

    Hi,
    I've created an interactive map that loads data from XML. The
    map is made from several areas (MCs, currently 16) - all positioned
    in a "mega MC" that holds the map together. The JPG are loaded
    externally respectively to the area MC that it belongs to.
    The problem is that the Map MC (that contains all the area
    MCs) is too big (around 6000X6000 Pxs) and therefore slows down the
    computer significantly (The CPU reaches 100% usage). This happens
    also when there's no loading of the external JPGs - meaning, I
    think, that the problem is only with the "physical" size of the MC
    and not its actual MB size.
    I hope I was clear enough.. Would appreciate any help!
    Link to map

    Hi,
    I had a similar problem when I needed a really big area. I
    think the cpu usage wasn't that bad in Flash Player 7 and 8.5 (now
    9), but in Flash 8 it was really high. I decided to not move the
    big MC around, only the smaller parts that where needed. I guess
    the whole map is never shown completely, only parts of it, so you
    can write a scroll function that determines the active MCs and only
    moves those around instead of the big holder MC. To achieve this, I
    added a variable to each MC that holds the position of that part in
    the big MC. Then I kept track of the position of the display in the
    map, and used this to decide which parts are actually displayed.
    Only these MCs have to be moved when scrolling, reducing the cpu
    usage a lot. When a part moves out of the display, I set its real
    position to -5000, and when a new part comes into display, its
    position is set from -5000 to the proper _x value so it gets
    displayed.

  • Tab selection property causing 100% CPU usage

    Hi,
    I've having some trouble with using property nodes to tab selection. After 1-2 hours the CPU usage is 100%. The VI is attached. I'm using LV 6.0.2 on win2000. Does anyone have a clue of what's happening?
    Attachments:
    tab_selector_property.vi ‏22 KB

    Every time the while loop executes, you open *new* pages reference array. Whitout closing them, you quickly fill the memory and hog the computer usage. As in the modified VI attached, get the references only once outside the while loop and reuse them. Close any reference after use. As much as possible, you shoud use the control terminal to read its value instead of reading the value property.

  • Upgrade to iTunes to 10.4.0.80 caused 100% CPU usage when I start iTunes. Task manager shows iTunes 50% mobile 50%. I am running Windows XP Professional sp3. iPhone 3 ios 4.3.5

    I upgrade to iTunes 10.4.0.80. Since then iTunes uses 50% of the CPU and Mobile uses 50% CPU. I let it run for hours and the CPU usage stayed at 100%. The phone will partially sync but takes a very long time. This was not a problem before the iTunes upgrade. I am running iTunes on Windows XP professional SP3. It does not matter if the phone is connected to the USB port of the PC. When iTunes starts it runs the CPU at 100%.

    Yes!  I am not the only one with this problem.  Ever since the latest iTunes update, the CPU runs up to 100% using both the mobiledevice and itunes itself.  The store won't work either!  I'm also on Windows XP.  I too have tried everything I can think of but nothing has helped.  I really hope they get an update out with fixes soon.  This is really annoying!!

  • Why Xcode 4 causes 100% cpu usage?

    Dear all,
    I have been annoyed by the high cpu usage of Xcode 4.0.2 when editing code. It is burning my MacBook! I think this may be related to the dynamic code checking. Any idea?
    Cheers,
    Li

    dynamic checking?
    Do you mean Instruments...?
    AFAIK, it's always hungry, hungry hippo - the best defense right now is to use Xcode 3.2.6.
    Xcode 4 isn't 'required' just yet, but it might happen later in the year with the next OS, which may help tame it a bit.

  • Power cord causing 100% CPU usage on HP Pavilion dm4t

    Bumping this topic because the problem seems to still be puzzling the HP engineers. I'm using a 2011 HP Pavilion dm4t and the problem has occurred numerous times and seemingly at random with any power outlet I use. Almost desperate for a solution. Almost.
    Task Manager only shows Google Chrome, SVCHost, MsMpEng, and itself as the heavy users (>20% each).  Task Manager should not even be using more than 1% CPU as it's meant to be a minimum influence observer process.

    Symptoms for all HP 3 wires AC power unit: Works awfully slowly, even unusable on AC but works fine on battery. Battery does not charge or very slowly (25% after one night) on AC.
    This is the solution:
    First check the power plug, outside is the ground, 0V, innerside on the edge + 19V and on the middle pin + 5.75V (This last I read on a forum) but personnaly I had 19V on the middle pin and my Compaq 8510w slowed awfully down on AC.
    Whatever you have on the plug it means that the wiring is ok. Unplug the power unit and cut the wire (not too close to the plug). This cable is coaxial, on the first coat is the ground, the second the +19V and the tiny blue one on the center (Feedback?) is the one supposed  to have +6V more or less. From the PU side check for the +19V and cut the blue one you won’t need it anymore.
    Connect this two wires to the wires’ plug (+ and +, - and -). Between 0V and +19V make a bridge with 2 resistors in serial: 820 Ohms from +19V side and 330 Ohms to ground (Tested with 10K+4K7 but no way). Connect plug’s blue wire to the middle (+6V, but sometimes raises over 7V) of that bridge and that’s it. Be aware that your cable could be broken inside, generally nearby the plug. Could also be a problem with the power jack.
    Now you got the keys to make your own Power Unit using an universal AC power or car adapter.

  • 100% CPU Usage caused by HMI

    Hi everybody:
    I'm working with LabVIEW DSC 8.2.1 in a system that monitors many variables of a plant, such a typical SCADA system. For this reason, the use of the graphic tools is highly used on the development of this system. Everything works fine, but I have only one problem.... the usage of the CPU.
    When I am working on the development system I (not the executable) I start the application and after the variables are initialized and every process has started and are running , the CPU usage is raised around 90 - 100%. After a few days investigating the reason of this, I realized thay when I change the view on the screen to another view, for example the block diagram of the application, while the application is still running, the CPU usage goes around 15 - 25%. I've tried these many times changing the view from Front panel to Block Diagram and viceversa and the result is always the same: Front Panel= around 100%; Block diagram or another view (other applications MMIs, or Block Diagrams, etc.)= around 20%.
    Another thing that I realized is that the other view (different to front panel) has to fill the entire screen to work the way I'm telling before.
    When I build and run the executable, the usage of the CPU is the same... (around 100%), but I can't see any other application, because the application built is the shell of the OS, so no other views are available.
    I don't know if there's some other consideration to take into account about the HMI when creating an application, and I'll appreciate very much your help.
    Thanks in advance!

    100 Percent CPU Usage when you run programs after you install Windows XP Service Pack 2
    CPU Usage 100% Symptoms
    When you run some programs, the CPU Usage meter in Task Manager may indicate CPU Usage 100%. When CPU utilization reaches 100 percent, programs will run very slowly or stop responding (hang) and your computer is freezing or crashing.
    Noteress CTRL+ALT+DEL to view CPU utilization, click Task Manager, and then click the Performance tab.
    These symptoms occur after you install Microsoft Windows XP Service Pack 2 (SP2).
    CPU Usage 100% Cause
    These problem occurs because of the user interface code that is included in Windows XP SP2. The high CPU utilization is caused by the additional overhead that occurs when the IsWindow function is called by the user interface code.

  • Some web pages causing 100% CPU use of iexplore.exe since Flash update

    I'm having a problem with certain Amazon.com pages hanging my
    Internet Explorer 6 using Flash Player 10,0,12,36, causing 100% CPU
    use for iexplore.exe and requiring me to End Task to quit. All the
    pages effected have an interactive mouseover Size and Color chart
    that intially says "Loading" but then says "Select Size and Color"
    once loaded. One mouseovers the various color patches and size
    options, each time giving item availability in that option. When
    the pages hang the IE browser with 100% CPU use that chart never
    gets to the "Select Size and Color" point, instead stuck at the
    "Loading" status. This happens most times, but not every time.
    Sometimes the pages load correctly, after a brief lag as it loads
    the chart.
    Amazon pages without this chart load fine.
    The start of this problem coincides with updating Flash.
    I can prevent the problem from happening almost every time if
    I can quickly get my cursor into that chart area while the page
    begins loading. If I allow the pages to load fully with no
    interaction they will hang almost every time.
    I have not noticed any problems on those same web pages using
    Firefox using Flash Player 9,0,124,0
    I also have not noticed any issues with other sites using
    Internet Explorer either. (YouTube, QVC, CNN...etc, all OK.)
    I had posted for assistance on the Experts Exchange site and
    there was some debate on whether the chart was a Java or
    Flash-based chart, so initially it was being approached as a
    possible Java issue, so I removed all Java versions on the system
    and installed various versions, but the same problem persists.
    I've downloaded but not run the Flash Uninstaller, as I'm
    reluctant to uninstall the Firefox Flash version without knowing
    for sure I could install 9,0,124,0 again.
    I've downloaded an archived fp9_archive.zip, which seems to
    indicate the contained files flashplayer9r124_winax.exe (Internet
    Explorer) and flashplayer9r124_win.exe (Netscape) would be versions
    9,0,124,0 to install after running the uninstaller.
    Can anyone check a few of the links below and see if the
    "Select Size and Color" chart is Flash based? If so, would
    executing the files listed above install 9,0,124,0 into my
    respective browsers again?

    Thank you-

    I'm attempting to troubleshoot an issue with Amazon web pages
    since I've updated my Flash player. I would appreciate if someone
    could take a look at my initial post and advise if the issue seems
    to be Flash related.
    Thank you.
