There seems to be a serious memory leak with Safari running on Lion.  The Safari web content - is running crazy and essentially closing down by macbook pro......

 

I have reverted to using Firefox for now (everything works fine there even with Flash) - help????


MacBook Pro, Mac OS X (10.7)

    Huge CPU-hogging, memory-filling leak here, too on Lion.  +1 !!

     

    Safari Web Content always around 98% of CPU and 650MB of Real Mem.  This is even with click-to-flash keeping flash off my Safari and fewer than 6 tabs open

    Same here. Safari is unusable after about 5 minutes of browsing. I also have a flash blocker & only 2-3 tabs open at one time.

    Same problem as everyone else. Really high memory usage. Hoping for a fix soon, it's ridiculous as it is right now

    There seem to be two problems.

     

    1.  Every tab takes memory, but closing them does not return it.

     

    2.  Some content causes the memory usage to rise over time. 

     

    It's surprisngly bad.

    Same here in 10.6 running Safari 5.1 even with just three tabs open.

     

    Safari Web Content memory usage goes over 1GB and the whole Mac slooowwws down.

    On the flip side of this coin, running Safari 5.0.5 on Lion has me still seeing memory gobbling at four times what it needs on Snow Leopard.

     

    My wife's MBP just sitting with one page open grabs about 83MB of memory, while my iMac running Lion and 5.0.5 is currently at 415MB.

     

    It's obvious that Safari 5.1 is a memory hog, but Lion itself has a leakage problem all its own.  I'm about ready to take my iMac back to SL and wait until Apple issues a few more updates.  The delay since Lion's availability is completely unacceptable.

    Me too.

     

    I have Gmail open on one page, a Google chat window and this Apple Support Communities page open. RAM used 230MB and rising.

     

    I had one extension installed: ClickToFlash.

    Disabling it and restarting Safari made no difference.

    Uninstalling it, and turning Extensions "Off" made no difference.

     

    I wondered if it might be Sophos AV - disabled "On Access Scanning": no joy.

     

    I see this problem with Safari Version 5.1 (6534.50) on Lion 10.7.1 and Snow Leopard 10.6.8; different hardware (1 x 17" MBP, 1 x Mac Pro and 1 x Mac Mini).

     

    I hope this gets fixed soon!

    I'm done, and am making preparations to go back to SL until a few more updates happen.  I can't put up with the two or three daily re-boots to clear memory consumption doing basic functions.

     

    Even running Safari 5.0.5 eventually eats up all available memory, with subsequent spinning beach balls, which is ridiculous.

     

    Over a month with nothing from Apple addressing this fiasco.  It appears that they are ignoring the issue, hoping it goes away on its own.

    I'm back on SL as of Saturday night.  Original install disc with a restore from Time Machine.  About three hours total, and everything works as before, with no memory leaks and Safari 5.0.5.  The near back-to-back comparison is amazing, and my 27" iMac is happy.

     

    No more delays opening applications or utilities.  I wondered why Software Update took three to four seconds to open under Lion, but SL's opens immediately.  This and even the simple Textedit are just two examples of software that opens faster under SL.

     

    Apple, you've got some work to do.

    Lol, and I have done the extreame!! I have switched back to Windows!!! I must say its been great so far. No complains as YET!

    Back to WinBlows?  Not a chance.  I value my time far too much to be babysitting a kludge.

    It's been a loooong time since my original post. I think the Safari memory leak was fixed.

     

    I toughed it out - was closing/re-opening Safari throughout the day (and *never* left it running over night!). But that seems to have been fixed months ago.

     

    I definitely wouldn't unswitch to M$FT...
