Flash Player goes nuclear - takes down entire network

We have 10 Windows computers on a  small unmanaged gigabit network with a DD-WRT Linksys WRT-54GS router  and Dlink 2208 hubs, and were having problems with the network dieing,  and nobody able to reach the internet or other computers on the network.  It started happening suddenly.  There are additionally 3 VOIP lines on  this network too and they would be killed.
In  troubleshooting, I could see an enormous amount of activity coming from  one section of the network.  Disconnnecting this segment brought the  network back online and functioning correctly.  Further tracing based on  the flashing lights on the front of the hubs narrowed the problem to  one computer, a new Windows XP-64 bit computer.  When I brought up the  Local Area Connection Status in Windows, I could see an enormous number  of packets being sent.
Close to a million packets per second were being sent from this computer.
Adobe  Flash Player (ver 10,1,82,76) was taking a tremendous amount of CPU  time for an idle computer, and killing this in task manager resulted in  the network coming back alive immediately.
Is this a known problem with Adobe Flash going nuclear and killing an entire network?  I had this problem twice before and was never able to trace it to my satisfaction and now I wonder if this was what happened.
(was originally posted in Flash but I suppose I should have posted it here since it is a player problem)

Yes, sometimes Flash Player doesn't close down when Firefox is shut down.  I didn't find any gremlins on my computer during virus analysis, so can't comment on that.  I suppose I could find the problem site and SWF, but since I didn't develop it, my concern with Flash is that it can get into such a snit, that it can take down an entire network and not just a computer.
My concern is summarized this way.
1. Was there something else on my computer that caused this problem. (virus etc)
2. If it is Flash causing this problem, perhaps Steve Jobs concerns with Flash were legit??  (I see Apple has backed down)
3. Grandma certainly wouldn't have been able to resolve this issue, and most computer users would have blamed their ISP since their internet was down.
4. How is the average computer user to deal with the complexity that these new technologies sometimes dump on them?
5. Are we headed to systems that are so complicated that these type of isses become more and more common?

  • Server 2008 R2 SP1 with RRAS takes down entire network

    We have a Hyper-V server (2008 R2 SP1) that is running several DC's.  These DC's are for different domains and establish outbound VPN connections using RRAS to sync with remote DC's.  We have a few of this with 20-30 DC's running on each Hyper-V
    server.
    Application of SP1 to the host OS went without issue and everything remained normal.
    Upgraded a single Hyper-V VM from 2008 R2 to 2008 R2 SP1 and everything connected to the physical switch went down.  Ping times went through the roof and timeouts were happening on the local physical network.  All Hyper-V guests on all
    Hyper-V machines had CPU usage that went from about 0% up to averaging 5% to 7%.  The processing taking all the CPU was the LocalServiceNoNetwork one which is related to packet inspection.
    Using the process of elimination, we found that if we stopped RRAS on the Hyper-V guest running 2008 R2 SP1 then everything went back to normal.  We duplicated the same scenario with a different machine...and again, just stopping RRAS fixed everything.
     As soon as RRAS starts, the network crashes.
    Has anyone else seen anything like this?  I plan on opening a case with PSS tomorrow but thought I'd ask.

    PSS is useless.  They work on the ticket when convenient for their overseas hours and have no idea what is wrong.  They keep asking for the same information over and over.  We've decided to remove the RRAS component from our VM's.  Instead
    we've decided to set up a VPN configuration where we use IPSec tunnels for each VM.  This allows us to remove all the RRAS roles and the issue goes away with SP1 applied.
    There is definitely something wrong with SP1, RRAS and Hyper-V.  Maybe Microsoft can figure it out on their own time.  It is easier and simpler for us to just remove the component.
    For historical reference, the issue seems to be that RRAS with SP1 picks up packets that are not destined for the RRAS tunnel and attempts to retransmit them.  This, in turn, saturates the switches with retransmit packets and takes down the entire network.
    Microsoft has absolutely no clue on how to resolve the issue and the techs have so little knowledge in real networking troubleshooting that it is laughable.

  • I downloaded a adobe flash update and my computer and after next logon got a blue screen.   could only start in safe mode and until uninstalling the flash player could i safe mode with networking.  i cannot open any microsoft products now. I get a message

    i downloaded an adobe flash update and my computer after next logon got a blue screen.  I could only start in safe mode and until uninstalling the flash player could i start in safe mode with networking.  i cannot open any microsoft products now. I get a message saying adobe acrobat 10 is not designed to run on windows or uninstall and reinstall it ....but it will not let me uninstall it.  What do i do?  is this all an adobe issue or a windows problem??  thanks   Tim

    Hate to suggest this, but you need to ask in the Flash forum. This forum is for Acrobat.

  • Flash player goes green and crackling

    For the last couple of months any time i use the flash player for anything after either a few mins or even a few seconds the video stops, the timer on the bottom starts fast forwarding and the screen goes green. All you can hear then is a crackling sound.
    I have then most up to date version of flash player the v 17, i'm using firefox - although i've tried to use internet explorer to see if there was a difference and the same thing has happened. I've tried to do all the steps in the adobe list (disabling hardware acc etc.) but it still happens and i've updated all my drivers. I'm currently using windows 8.1
    Any suggestions would be great as its getting very frustrating not being able to watch anything!

    This is most likely a bug in the GPU drivers.  You'll need to disable hardware acceleration to work around the issue until a patch becomes available from the GPU vendor.
    Please see the video troubleshooting guide for instructions on disabling hardware acceleration:

  • Adobe flash player 10.2 slows down then locks up Internet explorer 9

    I have new windows 7, IE9 (which is great), but when new adobe flash player 10.2 installed, slows IE9 a lot and after switching to a few different sites, locks up IE9 completely. This is on all 3 of our computers. Uninstall newest flash player, IE9 runs smooth and fast once again. I have tried all ways, to install player first, then update IE8 to 9, and vice versa, nothing changes the outcome is always the same. I love IE9 because it's so much faster loading than IE8, but this flash player issue is a real headache and can't figure out why. Is there a patch for this? What is the problem? Thanks for your help

    Okay, thanks for your advice, which gratefully turned out to be good advice!  I downloaded and installed Adobe Flash Player 10.2.152.32 assuming that Adobe Flash Player 10.2.152.32 would replace my previously existing Adobe Flash Player 10.1.102.64 installation in my Mozilla Firefox Web browser.  At a similar time that Web browser was updated from version 3.6.13 to version 3.6.14 of it.  In Firefox's "Tools" menu's "Add-ons" I could then see "Shockwave Flash 10.2.152.32" and "Shockwave 10.2r152" listed and assume that those are two designations of the same add-on.  In 32-bit Windows XP Home Edition I returned my Hewlett Packard notebook computer's S3 Graphics TwisterK HP card's video memory to 16 MegaBytes (MB) via "Start, Control Panel, Display, Settings, Advanced, S3Info Plus" and on the drop-down list box selecting 16 MB instead of 32 MB; after that I clicked on "Apply" and in the successful change clicked on "Yes" to a necessary restart of my computer to effect the change, and may or may not have clicked on one or two "OK"s.  I tested the new Flash Player by playing and watching a portion of the movie under "Adobe Flash-Video Test" on the Web page http://www.chemgapedia.de/vsengine/info/en/help/requirements/flash.html.  The video and audio signals of the movie there gratefully appeared to be fine, other than the not-surprising waiting periods for data to be received on my computer from the Internet using my slow, but cheap dial-up Internet service.  Thanks again for what proved to be good advice for me!

  • New iMac slowing down entire network's internet

    I recently purchased a new iMac (warning, I'm a PC user up until a few days ago), and have noticed that any time I have the iMac on (idle, having just started up) the internet for the other 2 computers on the networks drags terrible (long page load times, etc)
    It's as if the new machine is hogging up all the bandwidth, while doing nothing.
    I've experienced this problem in the past, when my younger brother was home from college & had his macbook. Any time he was on his macbook, the connection for the rest of the network would become unreliable. This was on a completely different network from the one I'm currently having a problem with.
    Has anyone else run into this problem?
    Being new to Macs, I'm not even sure where to start looking for the problem.
    Any help/feedback would be greatly appreciated.
    Thanks.

    Welcome to Apple Discussions.
    I'd start by going to System Preferences > Network click on Ethernet or Airport or both and be sure your setup is correct. There's an "Assist me" button in each.
    EDIT: I'd also suggest you take a look atSwitch 101. There's a wealth of info there.

  • Video on flash player goes slow from every site

    if i use chrome, the same video goes well. with firefox it goes too slow, and frequently stops, also if i disable hardware acceleration (i have a quad core, and an ati hd 6870)

    Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.
    *Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
    *Do NOT click the Reset button on the Safe Mode start window
    *https://support.mozilla.org/kb/Safe+Mode
    *https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes
    You can check for problems with current Shockwave Flash plugin versions and try this:
    *check for updates for your graphics drive drivers<br>https://support.mozilla.org/kb/upgrade-graphics-drivers-use-hardware-acceleration
    *disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)

  • Imac slowing down entire network internet

    just hooked up a 2009 imac 21.5 intel to my home net work. now evry computer in the house nas a super slow internet connection including the imac when i disconnect the imac evything is fine i have adsl connection  the app on my iphone is showing between 12-15 without imac and barely 1 with it (download speed)
    Even if i hard wire imac to modem same problem
    HELP!!!!

    No, OK lets check one more thing on the router. First routers have multiple channels, however most people NEVER change the channel their router is on. If you live in an area where there are lots of WI-FI networks that means you and neighbors could be competing for the same channel. You can download an app called iStumbler from macupdate.com and it will scan your neighborhood to see what channel you and your neighbors are on. If you find you are on the same channel as your neighbors (usually channels 5 or 6) then you can change the channel on your router. Again you'd have to call Verizon to get instructions.
    After that change and if you still have the problem the next thing to do is change the DNS settings. This is easy to do and causes no harm. For instructions click DNS Settings Update.

  • Adobe Flash Player stopped potentially unsafe operation - Experts, help!

    Greetings!  This message is posted in this section (and in Flash Player, too) because the primary program I am using for my webste is Dreamweaver.  So, if you can help me, I would really appreciate it....
    This message above made me very nervous.  Here's the rest of what the message said:
    In the Title Bar - It reads "Adobe Flash Player Security"
    Then in the message section:
    The following local application on your computer or network:
    C:\ (the address of my index page - using Dreamweaver & Flash CS3)\index.html
    is trying to communicate with this Internet-enabled location:
    s.ytimg.com
    To let this application communicate with the Internet, click Settings.
    You must restart the application after changing your settings.
    Then - buttons with the choices "OK" and "Settings..."
    So, in addition to this pop up message, now when I link to some (not all) of my newer pages, the nav bar no longer works when I'm on that linked page.
    I'm pretty worried that I've done something really wrong or that a virus is going to take down my site.
    Can anyone provide me with encouraging help that will resolve this problem?

    Thanks in advance.

    It's simply a reference to the YouTube video. When viewing pages locally and not live on the server, adding security exceptions may be required, so I don't think it is anything out of the ordinary...

  • Flash Player 10.3 and Internet Explorer 9 update and workarounds

    Hello Flash Player community,
    We are tracking the issues being reported on Flash Player 10.3.181.14 and Internet Explorer 9 and actively investigating them.  Users are reporting that Flash content is being displayed in the upper left corner of the screen.  We want to give those who are encountering these issues an update.
    First, we apologize to everyone affected.  We know you count on Flash Player as an integral component of the web and we strive for high quality and performance in each release.  We are actively looking into the root cause of this issue.  Thanks to many of you submitting information via email and our online bug database, we now have some solid leads we are pursuing.
    Flash Player 10 and later can use your system’s graphics hardware to accelerate video decoding, and can also accelerate video presentation on some sites. Starting with Flash Player 10.2, Flash Player will also take advantage of hardware accelerated graphics in Internet Explorer 9, utilizing hardware rendering surfaces to improve graphics performance.
    With Flash Player 10.3.181.14, reports indicate that systems with Intel HD Graphics adapters running Internet Explorer 9 are the only systems impacted by this particular bug.  If you are encountering this issue and have a different configuration we'd love to hear from you.  Please review the instructions on this page for details on generating the information we'll need for further investigation.
    Solution #1
    Adobe has officially released Flash Player 10.3.181.16 for Internet Explorer to address the graphical issues introduced in 10.3.181.14.  You can get this release by visiting our official download page, directly downloading and running the installer file, or using the Flash Player auto update mechanism.
    After installing, we recommend you re-enable hardware acceleration if you had it previously disabled.  We also recommend you clear your browser cache and restart your system.
    If you continue to encounter issues, please create a new thread and we'll do our best to investigate further.
    Solution #2
    On some systems, you may be able to resolve this issue by updating the Intel HD Graphics drivers. It has been reported that driver versions 8.15.10.2361 and above do not exhibit this bug. Unfortunately, some systems might require updates directly from your system manufacturer. We’re working with system manufacturers to make sure they include the latest drivers in future releases.
    Solution #3
    You can disable hardware acceleration in Internet Explorer 9 using the instructions on this page. Please note that you should re-enable hardware acceleration once this problem has been resolved to enjoy the full benefits of hardware acceleration.
    Thank you,
    The Flash Player team
    Update 5/20/11 - We've temporarily disabled the automatic update notification for Flash Player 10.3 and Internet Explorer.  We're making progress on a fix and hope to have a new version available next week.
    Update 5/24/11 - Added link to the 10.3.181.15 test update
    Update 5/27/11 - Added instructions for post install of 10.3.181.15
    Update 5/31/11 - Updated thread with the official 10.3.181.16 announcement

    FOR THOSE RUNNING IE9 ON WINDOWS 7 AND HAVE INSTALLED THE AUTOMATIC UPDATE FOR ADOBE FLASH PLAYER 10.3 - TAKE THE FOLLOWING STEPS:
    Open IE9 Browser window > Click on "Tools" > Click on "Internet Options" > Selct the "Advanced" Tab > Turn on/Click the "Use software rendering instead of GPU rendering" > Click "Apply" > Click "OK" > Shut down and then restart your IE9 browser.
    THIS WILL BE A TEMPORARY FIX FOR ANY ISSUES YOU MAY HAVE WITH THE CONSTANT FLOOD OF FLASHING ADS AND THE LIKE UNTIL A PATCH IS MADE AVAILABLE FOR THIS UPDATE.
    OTHER QUICK FIXES WOULD INCLUDE:
    1) UN-INSTALLING 10.3 AND RE-DOWNLOADING AND INSTALLING 10.2 FOR THE TIME BEING. **BE SURE TO AVOID RE-INSTALLING THE AUTOMATIC UPDATE OF 10.3 AGAIN**
    2) DOWNLOADING AND INSTALLING "MOZILLA FIREFOX" AND USING IT AS YOUR WEB BROWSER!!

  • Adobe Flash Player 10.3 upgrade is essentially a computer virus...

    Adobe Flash Player 10.3 upgrade is a worldwide disaster -- I am losing money every second because Flash screens now appears in the upper left-hand corner of the browser screen -- the user experience is ruined until Adobe finds the time to properly test a new upgrade release -- leave it to the "rookies" at Adobe to release a software upgrade that automatically loads, but then does not work -- Adobe Flash Player 10.3 is essentially a computer virus that is being installed globally...

    FOR THOSE RUNNING IE9 ON WINDOWS 7 AND HAVE INSTALLED THE AUTOMATIC UPDATE FOR ADOBE FLASH PLAYER 10.3 - TAKE THE FOLLOWING STEPS:
    Open IE9 Browser window > Click on "Tools" > Click on "Internet Options" > Selct the "Advanced" Tab > Turn on/Click the "Use software rendering instead of GPU rendering" > Click "Apply" > Click "OK" > Shut down and then restart your IE9 browser.
