Memory leak in Safari 4 & 5

In 10.5 and 10.6, Safari has what I think is called a memory leak. It ties up memory that it is not actually using, so that its use balloons. I can quit and re-open all the same windows and gain half a gig of memory back.
Anybody know a way to stop this?

There is an on-going thread from Aug 2009 about "Snow Leopard" and "Memory Leak" or similarly "Memory Hog" etc and not releasing memory as well as how Safari is one of the worst offenders for many others.
Some have 4GB RAM and no trouble, some with same amount but do.
And of course clearing Previews, History, Cache, even the Bookmarks cache.
~/Library/Caches/
Flash and other plug-ins, (flash has its own cache) and using something to only load Flash if desired.
But most found 10.5 and Safari 4 "better behaved" and not the issue 5.0 and 10.6 are.

  • Inactive Memory leak in Safari 4.0.3

    There is a memory leak in Safari 4.0.3. I haven't isolated it to a particular page since I usually have 15-20 tabs open when I notice the spinning ball, caused by VM paging. When this happens, according to Activity Monitor, Safari.app uses between 500-2000mb of "Real Memory", yet when I close it almost all of the blue "Inactive Memory" is released. The last time this happened, it freed 5.4gb.
    This is getting annoying and is certainly bad for the SSD. Any idea if there's a fix?
    BTW I've got the new Pro with 8 gigs of DDR3 and an SSD, and 20mbit FIOS internet... There is no excuse whatsoever for the spinning ball!

    The way Safari accumulates memory is normal. The way it is trying to page the memory to disc and error-ing is not. I think the integrity of your disc volume / catalog and directories may be to blame.
    Try a bit of basic maintenance:
    Repairing permissions is important, and should always be carried out both before and after any software installation or update.
    Go to Disk Utility (this is in your Utilities Folder in your Application folder) and click on the icon of your hard disk (not the one with all the numbers).
    In First Aid, click on Repair Permissions.
    This only takes a minute or two in Tiger, but much longer in Leopard.

    If you were having any serious problems with your Mac you might as well complete the exercise by repairing your hard disk as well. You cannot do this from the same start-up disk. Reboot from your install disk (holding down the C key). Once it opens, select your language, and then go to Disk Utility from the Utilities menu. Select your hard disk as before and click Repair.
    Once that is complete reboot again from your usual start-up disk.

  • Serious memory leak in Safari 5.1.2 for Lion

    Safari keeps on using memory and frees up almost nothing even after I close the web page.

    You didn't REALLY believe they FINALLY fixed the leak, did you?
    Safari's been leaking for years, no reason to believe they'd fix it now, regardless of what the release notes say.
    You're unlikely to see any difference in memory usage by closing one or two pages.

  • Memory leak in Safari WebFeedParser

    Lately I've noticed that every so often a process com.apple.Safari.WebFeedParser is taking up more memory than it should be. Often times Has anyone seen this problem or know the cause of it?

    Back up all data before proceeding.
    Quit Safari if it’s running. Then select
               ▹ Force Quit…
    from the menu bar. A small window will open with a list of running applications. Safari may appear in that list, even though you quit it. If so, select it and press return. Close the window.
    Step 1
    Hold down the option key and select
              Go ▹ Library
    from the Finder menu bar. Delete the following items from the Library folder (some may not exist):
              Caches/com.apple.Safari
              Caches/com.apple.Safari.SearchHelper
              Caches/com.apple.SafariServices
              Caches/com.apple.WebKit.PluginProcess
              Caches/com.apple.WebProcess
              Caches/Metadata/Safari
              Preferences/com.apple.WebKit.PluginHost.plist
              Preferences/com.apple.WebKit.PluginProcess.plist
              Saved Application State/com.apple.Safari.savedState
    Leave the Library folder open. Try Safari again. If the problem is solved, stop here. Close the Library folder. If you still have a problem, continue.
    Step 2
    Move the following items from the open Library folder to the Desktop (again, some may not exist):
              Cookies/Cookies.binarycookies
              Internet Plug-Ins
              Preferences/ByHost/com.apple.Safari.*.plist
              Preferences/com.apple.Safari.Extensions.plist
              Preferences/com.apple.Safari.LSSharedFileList.plist
              Preferences/com.apple.Safari.plist
              Preferences/com.apple.WebFoundation.plist
              PubSub/Database
              Safari
              SyncedPreferences/com.apple.Safari.plist
    Here, "*" stands for a long string of letters, numbers, and dashes.
    Note 1: You are not moving the Safari application. You’re moving a folder named “Safari.”
    Note 2: This step will remove your Safari extensions, if any, and their settings. If you choose to reinstall them, do so one at a time, testing each time to make sure you haven’t restored the problem.
    Try again. Your settings and bookmarks will be lost. The default set of bookmarks will be restored. Delete them all.
    If Safari is now working normally (apart from the lost settings), look inside the “Safari” folder on the Desktop for a file named “Bookmarks.plist”. Select
              File ▹ Import Bookmarks...
    from the Safari menu bar. Import from that file. Recreate the rest of your Safari settings. You can then delete the items you moved to the Desktop.
    If the issue is still not resolved, quit Safari again and put all the items you moved to the Desktop back where they were, overwriting the newer ones that may have been created in their place. You don’t need to replace the files you deleted in Step 1. Stop here and post again.
    If you don’t like the results of the last step, you can undo it completely by quitting Safari and restoring the items you moved or deleted in that step from your backup, overwriting any that were created in their place.

  • Safari Flash Player Memory Leak?

    I recently got a new macbook pro, 13" model (with the 2.2 GHz dual processor). Last night I noticed that it was running pretty slowly, something that I figured was weird considering the amount of power it has compared to my four year old desktop computer. I managed to isolate the problem: a memory leak with safari's flash player. I watch a lot of netflix and some TV episodes...and it turns out that the flash player accumulates up to 2 GB of RAM by itself. My pro has 4 GB of RAM and it never goes above 50% of that memory unless I watch videos. Only way to get around the problem is to force close the flash player application...but it's annoying to have to reload what I was watching. Any ideas on the fix for this?

    Far as I know, Netflix doesn't use Flash, it uses Silverlight.
    Your Flash likely got pwned.
    So check here and update both

  • Safari 4 memory leak?

    With Safari 4 open for only 12 hours, it's VSize has already grown to over 35GB while it's RSize stays around a couple hundred MB. Any other users experiencing this?

    Thanks -M@ for the post.
    I've been waiting for Chrome to come out of beta.
    When I first checked the VSize of Safari 4 on Dec 31 after it was open for about a week, it was close to 100GB! Before Safari 4's release, I could play any of my 1000 Logic Express 8 files without stopping because of insufficient system RAM, although it was close to the limit my 2GB provided. Logic Express 8's built-in CPU monitor would show one core peaking when the first notes were played but the music continued on to finish as both cores would then fairly equally share the processing load. After Safari 4's release and with the browser open for any appreciable length of time, I couldn't get past the first note on any of them the first time I tried to play them. They would play the second time I tried. System resource allocation was slow because of Safari 4?
    Also post-Safari 4: Every other day, I was losing 100-300MBs of hard drive space after waking up my Mac. A shut down would restore the space back. Something to do with routine maintenance tasks and Console logs? As long as I close Safari before sleeping my Mac, this has not happened.
    By the looks of other related topics in Safari for Mac discussions and the response here by Barry on Jan 1, there appears to be no performance issues related to any memory leaks in Safari 4, which makes me think my VSize problem is a Core Duo and/or Tiger specific one.

  • Memory leak issues persist in Safari 6.0.5 (it's about time that Apple actually fixed this)

    Safari has been notorious for its memory leaks for years, as I'm sure many of you know. I stopped using Safari as my main browser in 2010 or so, and I instead began to use Chrome. However, I recently had to use Safari to access some webpages, and I neglected to quit out of it. A few hours later, my computer slowed to a complete crawl. I was confused, because my computer never slows down to such a crawl, so I went into Activity Monitor to find the 'Safari Web Content' process using all of my available RAM, which was nearly 6 GB. Needless to say, Safari was force quit after that. I've heard that some plugins will cause this, but Flash was my only active plugin. Flash is, indeed, a heaping pile of crap that will readily eat resources as it sees fit- but this never happens to me in Chrome, and I use Flash all of the time n Chrome. This was after it had been sitting idle for quite some time, and I imagine that it would have used more RAM if it could.

    Using 6.0.5 here without any of those issues ...
    Regardless of whether Flash is being used, from your Safari menu bar click Help > Installed Plug-ins.
    Try troubleshooting extensions and third party plug-ins.
    From your Safari menu bar click Safari > Preferences then select the Extensions tab. Turn that off if there are any installed. Quit and relaunch Safari to test. If that helped, turn extensions back on then uninstall one a time to test.
    If it's not an extensions issue, try troubleshooting third party plug-ins.
    Back to Safari > Preferences. This time select the Security tab. Deselect:  Allow all other plug-ins. Quit and relaunch Safari to test.
    If that made a difference, instructions for troubleshooting plugins here.
    my computer slowed to a complete crawl.
    Checked to see exactly how much space is available ??
    Click your Apple menu icon top left in your screen. From the drop down menu click About This Mac > More Info > Storage
    Make sure there's at least 15% free disk space.
    Checked the startup disk lately?
    Launch Disk Utility located in HD > Applications > Utilities
    Select the startup disk on the left then select the First Aid tab.
    Click:  Verify Disk  (not Verify Disk Permissions)
    If the disk needs repairing, restart your Mac while holding down the Command + R keys. From there you can access the built in utilities in OS X Recovery to repair the startup disk.

  • Safari web process - memory leak?

    Mac Pro seemed to have slowed to a crawl.
    Safari 5.1.2 on SL 10.6.8
    Activity Monitor showed I was low on memory - over 7GB was being used by 'safari web process' - slowly close all open pages until only left with two - one was simply the 'bing' home page, the other a page that had failed to load.
    Anyone else had this kind of thing recently?

    Safari has a known memory leak. Open teh Activity Monitor, sort the list of apps by Real Memory column. You will find one called Safari Web Content. This is the cause. If you are running an safari extensions, they use SWafari Web Content to run, you can try turning off your extensions to see if that helps. About the only know fix now, is to close safari regularly. 5.1.2 was suppose to close some leaks but has not. There are reports you can run safari in 32bit mode but I haven't confirmed if this helps or not.

  • Memory Leak in latest Safari (5.0.4)?

    Since I updated to the latest Mac OS/X update Safari's memory usage seems to be increasing in a way that looks like a memory leak. I usually leave my mac running all of the time and find that after a few days Safari is using over a 1GB of real memory and 3-5GB of virtual memory. Sometimes it also seems to freeze — with the disk churning in the background when I try to switch to it.
    It may be related to viewing high-resolution images (it seems to happen more often if I view very high-resolution pictures, for example Nasa Picture of the Day).
    Anyone else seeing these issues? Occasionally it crashes when I try to kill it — I'll post the dump info next time.

    Hi,
    Delete the Safari cache and history more often, not to mention restarting your Mac.
    Disable plug-ins in Safari / Preferences - Security. See if that helps.
    Check Safari / Preferences - Extensions.
    Occasionally it crashes
    Post a crash log so we can try and help if emptying the cache and history trail / plugins / Extensions aren't the issue.
    If Safari has just crashed, press the Report button on the CrashReporter dialog box to view the crash information.
    Now copy/paste the entire contents of the Crash Reporter window into your reply here. If the crash report dialog does not appear or the crash is hard to reproduce, crash logs can be retrieved from the ~/Library/Logs/CrashReporter> folder.

  • Safari memory leak

    does anyone have any idea if this will EVER be resolved. If I leave my safari open it gradually eats up all my ram!
    Its been happening for tooooo long.
    I expect more from Apple.

    Hi Laura
    Yes, the memory leak is a definite problem that people in the open-source community along with Apple are attempting to resolve. To some extent, the same problem occurs with Firefox. Best remedy at the moment is to "quit Safari", then restart, which resets the memory requirement to a more manageable level.
    I have noticed certain web sites tick up the memory usage, called "World Leaks". Some of these are Java driven sites, others Flash driven. Even some of Apple's web site pages seem to contribute. The web is evolving rapidly. It's quite a can of worms to contain, monitor and coordinate.
    Hope that helps clarify this issue.

  • Safari 3 / Flash memory leak

    I recently upgraded to Safari 3.0.4 and am noticing a huge memory leak problem if I leave a Flash-enabled page open for any length of time. I monitor the Virtual Memory usage of Safari using Activity Monitor. Usage goes from around 280MB to as high as 2.65GB before I have to shut down Safari for my 1GB machine to be usable.
    See additional discussion here:
    http://forums.macrumors.com/showthread.php?p=4610322
    Does anyone know if this is a webkit issue, Apple/Safari issue, or a Flash issue?

    Hi
    Welcome to Apple Discussions
    On my machines, Safari has had challenges with World Leaks since the beginning (right now it is using 750 mb of RAM with 38 tabs open on one window). A bit excessive, however, it's not a red flag given the amount of RAM and processor speed of the iMac. Nonetheless, it ought to be a lot more efficient with RAM usage. I would use the latest WebKit build, however, some of my Safari add-ons would be incompatible.
    BTW, I too see jumps in usage, especially when accessing Flash content. The "only" way out is to quit/restart. Important to send feedback to Apple via the Safari Menu>Report Bugs to Apple.

  • Safari + Javascript = Slowdown and Memory Leak?

    I've pinned down what I think is some problem with Safari and Javascript.
    If I leave Safari open for over 24 hours, with several pages open in tabs, in Activity Monitor Safari shows about 1.38Gig of VM and Safari is molasses slow.
    Turning off Javascript immediately restores the speed in Safari but the HUGE VM usage remains.
    So, I turned off Javascript, relaunched Safari, opened the exact same sites in tabs and left Safari sitting there for 24+ hours. It's now using only 203MBs of VM and it's still swishy fast as it should be.
    It seems like a problem between Safari and Javascript. Can anyone else confirm this phenomena before I send an official report to Apple?
    Thanks:)

    Confirmed. Running Safari with the Debug option on will tell you that there are some memory leaks with JavaScript objects.

  • Memory leaks continuing in Safari and Web Kit

    Will Apple ever fix the Safari memory leak?
    As many of you know lots of reports over the years of Safari & Webkit having problems with memory leaks, and haven't seen a fix to it yet. This is a very important factor for usability of Safari.
    A memory leak is when, after a period of time, your browser, which is the online field that's designed to function like a page and is used to access web pages and surf the World Wide Web, consumes more and more of your computer's memory until it reaches a point where it literally becomes impossible to use your computer. It's like your computer's stuck in cyber mud. You have to close any open software program or restart the entire computer.
    Safari starts about 426.9 MB of real memory and 412.6 MB of virtual memormy and can go up to 1Gb of memory.
    Has anyone come up with a fix to this problem ? If anyone has a workaround for this, please share it.
    Meanwhile, Apple really should eliminate this problem once and for all.
    FYI, I'm using Safari version 5.0.3 and the latest WebKit r72487 which was built on 21 November 2010.

    My experience is that the same thing happens with Firefox and Chrome. The only difference with Chrome is that since the tabs are separate threads, they consume memory separately. The nice thing about that is that once the tab is closed memory is instantly freed. However, the helper thread always gets larger. Whether this is a memory leak or a consequence of having an application open over a long period of time is -I believe- open to discussion. I have experienced similar results with Eclipse (a memory intensive application). Daily shutdown/reboot and a few "Quit"s per a few hours fixes this issue. I don't know whether you would like to do this, though.

  • Memory Leaks   Unresponsive Mouse

    2009 8 core Mac Pro w/ 24 GB of RAM, ATI Radeon 4870, and a SeriTek PCIe eSATA card (card only has drives connected when running a manual drive clone).  When running Toast 10 or Parallels 9, my RAM will fill up (I use a program called Menu Meters to monitor stuff).  This machine worked just fine under OS 10.9 and earlier - no issues like this at all.  ClamXAV will also completely fill the RAM up (the meter will be full green, instead of part green, then mostly grey when Toast or Parallels fills it up).  I have to use Terminal to purge it so that the machine is usable.
    The other thing that happens is that sometimes when the computer wakes up or I am in the middle of doing something, the mouse will still move, but the dock will not pop open and the left button the mouse doesn't respond.  The right button will open the right click menu, but will not respond normally at all.  I have tried a different Magic Mouse, but the problem is the same.
    I thought that it may be a problem with the factory RAM and the Kingston RAM not playing nicely together.  So I ran it with just the factory 8 GB and then ran it with the Kingston 16 GB - the problem persists no matter which RAM is installed.  All of the RAM also passes the memory tests in Rember and TechTool.
    So, I need to find out if someone thinks that maybe the bluetooth module may be going bad causing the mouse issues.  I also need to find out what is causing the memory leaks.  I followed the steps that someone gave on this site to boot into safe mode, repair permissions, reset PRAM, then reset SMC (or the other way around - I did it like they said to).  It did nothing to fix the problem.
    I need some guidance here.  As I stated early on, the machine worked perfectly with OS 10.9.  I have WAY too much software that I use, so doing a completely fresh install is out of the question - I don't have time to reload everything.  This problem is annoying and I know that I am not the only one having these issues.  Any input will be greatly appreciated.  Thanks in advance.

    Here is the EtreCheck report:
    Problem description:
    Memory leaks when using Toast 10 or Parallels 9.  Mouse also become unresponsive (it will move, but left button does not work and dock will not pop open - mouse problem happens independent of the RAM being filled up - different mouse was tried with same result).

  • APEX 4.1.1 Memory Leak in IE7

    Hi,
    We busy upgrading our apex and db from 3.0/10G to 4.1.1/11.2G and notice that there appears to be a memory leak when using APEX. At one stage we have had IE7 using over a gig of memory.
    When you load or refresh your page IE7 seems to grab on average 2-5MB of memory for each page load. At first we thought it may have been our apps or setup but this also happens when we go to app 4550 page 1 on apex.oracle.com.
    How to replicate:
    Open task manager to view the Memory Usage.
    Using IE7
    1. Go to http://apex.oracle.com/pls/apex/f?p=4550:1
    2. Go back to Task Manager and note the readings once the CPU Usage for iexplore.exe has stablised to 0.
    3. go back to IE7 and press F5
    4. Repeat steps 2-3 and you will see the Memory usage increases.
    We think this maybe due to a few jQuery UI memory leaks within IE7 and thought this bug ticket maybe of interest http://bugs.jqueryui.com/ticket/7666 (Slightly different versions but similiar experiences)
    Could someone else confirm that they also experience the increasing or have had similiar problems and managed to resolve it?
    TBH, it wouldn't be an issue to use another browser like Firefox to access the builder but this also affects the applications if they include APEX standard Javascript and CSS.
    Thanking you in advance.

Don't have exact steps for replication or precise numbers, but I have noticed this in passing. On the junk that my client considers a PC suitable for web development the typical IE7 memory footprint with the APEX 3.0 builder and several other tabs running is about 52MB. Add APEX 4.1.1 and it climbs constantly until I have to pull the plug when it gets north of 150MB as the PC can't take it.
    As well that I also have Firefox and 4.1.1 is still experimental at that site...
    At the moment I don't have to resolve it and if I did the only option I'd propose is the replacement of IE7.

    I saw that eariler this week. I do agree with the concept though.So take appropriate action: charge extra for IE7 support.
    The amount of work and effort involved in making our website look normal on IE7 equalled the combined time of designing for Chrome, Safari and Firefox.Is entirely accurate. If it's stated as a requirement, itemise it as an extra on the quote.
    Educate management and bean counters: show them the one line of standards-compliant CSS that's all that is necessary in Safari, Chrome, Firefox and Opera (and just possibly in IE8/9/10), how it isn't supported in IE7, and the tortuous hacks and workarounds that are required to get something equivalent working there.
