Memory leak in airport process on Core 2 Duo MBP?

Hello!
I'm having a problem with my MacBook Pro Core 2 Duo (15"). It was slowing down rather rapidly after boot, so I pulled up Activity Monitor and found that the process "airport" had consumed 1.3G of Real Memory and 2G of Virtual Memory, plus 100% of the % CPU. I killed the process and it goes back to normal (importantly, without any impact on the wireless networking).
If I shut the screen and start it up again, it relaunches the airport process and it eats up the memory and processor all over again.
Anyone have any ideas what might be wrong? I've already repaired the permissions.

Detecting a memory leak in a process running on Solaris 5.7

Hi,
Iam running my application on solaris 5.7 platform.
I can see clear memory leak in that process.
Is there any tool or in-built functionality on solaris 5.7 to detect/fix that leak.
Thanks in advance,
Avvaru

Thanks for the reply. I already turned it off in both Safari and Spotlight preferences. However the problem persists. The process still runs, and from time to time it decides to leak all the memory as well. I really can't understand what the reason might be.
To be clear, in Safari-->Preferences-->Search-->Smart search field-->"Include Spotlight Suggestions" is un-checked. In Spotlight preferences all three "Spotlight Suggestions", "Bookmarks & History" and "Bing Web Searches" are un-checked. Process still runs under Spotlight as can be seen here:
After the last post I let it run for a while when it happened again, and below is just before i terminated it. Look at the memory usage!

Apple updates Airport for All Core 2 Duo Laptops.

AirPort Update 2006-002 improves AirPort compatibility in the following computers:
• MacBook Pro (15-inch Core 2 Duo)
• MacBook Pro (17-inch Core 2 Duo)
• MacBook (13-inch Core 2 Duo)
You may download this update from the Software Update in your computer or here:
http://www.apple.com/support/downloads/airportupdate2006002.html
After applying this update myself, it did not resolve the wireless issue I'm having at my university campus.

I managed to get 100% connectivity with my Core 2 Duo MacBook working flawlessly with my Airport Extreme router, and I'll tell you how.
After installing the latest Airport update, I did the following:
1.) I reset my router to it's default settings. I am using an Airport Extreme.
2.) I connected to the default settings, and tested bandwidth. Perfect.
3.) I ran Airport Setup Assistant (Applications/Utilities/Airport Setup Assistant), and configured my network with the settings below:
-WEP 128 encryption, with a 13-character password (mine was all letters)
-I changed the network's name from what it was to a new one
-I added OpenDNS's IP: 208.67.222.222
I restarted it, and tested the bandwidth again, getting the same results as with the unencrypted test!
So far no issues, having the other computers connected doesn't appear to weaken the signal or cause a dropout. Still getting a much more stable result.
I am now going to attempt to add the port forwarding settings I previously had in there, as well as the access list.

MBP core 2 duo MBP outpunching dual Quad Xeon MacPro/ATI Radeon HD4870-why?

Specifically, on the Mac Pro, in a Pro Res 422 HQ timeline, FCP generated text requires rendering in safe mode with a red bar and in unlimited RT (dynamic frame rate/quality) is showing as an orange render. On my old MBP, text plays back fine in safe mode, with a light green preview bar. Any ideas?

Just a guess but it may be a buried preference setting somewhere.
Use a preference manager to save current configurations, (re)save the project, trash the preferences on both and open the same project on both machines.
Let us know what happens.

Anyone know a good place to get a 2GB chip for the new Core 2 duo MBP 2.16

I jst sold my MBP 17 ionch fro the core 2 duo so I can have three GBs Of ram for ma audio apps. I am trying to find a decent priced 2GB chip unless there is a typo crucial says 929.00 I almost passed out. I used to get all my ram there but that is just too high any other suggestions

I wouldn't expect a big drop too soon. That's a lot of RAM density on a small board. Unless there's a major increase in demand I wouldn't expect much of a drop in price.
No doubt there may be cheaper prices than Datamem's. Although their prices are usually competitive, they are not always the cheapest. But they do offer good service, fast delivery, have a good return policy, and experience with Macs. My recommendation is based on a 10 year history with them which has been 100 percent satisfactory.
But $500 for a marginal 1 GB of RAM is a lot. I'm not convinced it's enough to warrant going from 2 GBs to 3 GBs. I have 2 GBs in mine and it seems perfectly fine for my needs.

New Core 2 Duo iMac Memory specification confusion

I'm confused about the memory specification for the new iMac (late 2006). In the article 303084, it says that the new iMac models, other than 17 " model, accept DDR2 PC2 5300 667Mhz SO DIMM. But in the other article ( 304284 ), it says that the memory is DDR2 PC2 5400 667Mhz SO DIMM. So which one does it take? I'm just about to pick up the new iMac tomorrow and I already have 2 sticks of 1GB of DDR 5300 lying around. Can I use these 2 sticks in the new iMac? The brand of the memory is Samsung. Are they compatible with the new iMac? For all you guys out there who upgraded the memory in the new iMac, which brand do you use? I live in Australia, so brands like Crucial and OWC are hard to find. The popular local brands here Samsung, Corsiar, Twin Mos and Kingmax. I bought the Samsung from a friend who pulled them out from a Dell Laptop which he hated and sold it after a week of ownership. Now he's a proud owner a new Macbook Pro with 2GB of RAM installed from the factory. I would like to a make good use of these 2 Samsung RAMs. Thank you.

P'Boy,
No worries. The PC2-5400 that appears in the article you cite is a misprint. The iMac Core 2 Duo takes PC2-5300 memory. I have the new Core 2 Duo and verified this by looking at the memory modules. While PC2-5400 may well work in the iMac Core 2 Duo, PC2-5300 is the type of memory specified by Apple to work with this computer.
Samsung is a fine brand, and is one of the brands used by Apple, so it should function just fine. Cosair is another fine brand, though I have not had occasion to use Cosair memory in a Mac (I've used it in a number of PCs).
Bottom line. Your Samsung PC2-5300 modules should work just fine. Enjoy your new Core 2 Duo!

MBP 2.33GHz Core 2 Duo, CPU temp constant 90 degrees C at high load

I have a 2.33GHz Core 2 Duo MBP. Not sure which chipset, but not Santa Rosa. I'm still running 10.5.2 because I don't want to stop the process I'm running at the moment.
Anyhow, I'm running both CPUs at full load, and the program I'm running is very SSE-heavy. iStatPro reads the CPU as running at 90 degrees C with the fans running at about 3800RPM. It's been running like this for several days straight because this is the fastest compute hardware I own. I have three PC case fans pointing at the notebook, so the exterior is relatively cool, as are the other temp readings, but the CPU temp makes me nervous. Various things I've read suggest that about 85C isn't so healthy for the processor. Is that true?
I did try calling Apple Care, but they basically blew me off, suggesting I use external cooling. I could take it to the Genius bar, but that'll be a good 3 hours of my time, so I need to make sure it's worth it.
Comments?
Thanks.

http://docs.info.apple.com/article.html?artnum=304882
and use that technique to make sure that no other heavy applications are crashing the party. There will be a number of smaller system apps and processes running; you're looking for a big hitter that you did not want.
I hear that the MBP is good for 100°C/ 212°F. I'm a little surprised that you're getting only 3800 rpm at 90°. Fans should be able to turn up to 6000 rpm. You may wish to download smcFanControl.
I use that program to increase the resting rpm from 2000 to about 2500 to give a head-start on any heat issues. At 2500, the fans are not noticeable unless I put my ear an inch from the the computer. The program also has a quick-change setting that lets you quickly bump the fan speed to the max of 6000 if things get too hot too fast.

Will Intel Core Duo image work with Intel Core 2 Duo image

I soon need to start preparing an image for the next school year since we are soon going to start moving into a completely new campus which images will need to be ready for lab imaging over the summer and the sooner I can have a lab image ready to be tested the better, but my question is......
If I create an Intel image on a "Intel Core Duo Processor " which we have currently, to then create this image and then push out two two complete brand new labs of what will be "Intel Core 2 Duo Processors"
I know in the past I have created images on the highest PowerPC computer (G5) and had the image on G3's, G4's, G5's etc. an work. I'm not sure if the difference in the processor will require the image to be made on the very same computer or not. If so, we will need to purchase one.
Anyways..... just wondering if someone has already tested this or played around with it?
Thanks,
Carter

The build version on the Core Duo models is not the same as the build version on the Core 2 Duo models. These individual builds are customized for their respective hardware. The only version of OS X that will be common for all Intel models will be a public build version that supercedes both custom builds.
The extant builds are here: http://docs.info.apple.com/article.html?artnum=303315. However, the table does not include the latest Core 2 Duo MBP.
If you upgrade all Intel Macs to 10.4.8 then an image of that version of OS X should be common to all Intel Macs.

Reliability on the MBP (Core 2 Duo) -- freeze wise

I'm currently using the last generation PB, but already sick and tired of the constant freeze issue, and seems like there's no solution to fix and there're more and more users experiencing the problem (check PB AL forum postings)
I think it's about time for an upgrade...
I would like to ask anyone who's using the Core 2 DUO MBP, did this problem go away when the book switched to Intel? Any freeze during idle, or from wake up etc? How would you rate it in terms of reliability?
Thanks for your comment

I don't care if the thread is 100 pages long. You won't find me on such a thread. The only way you can really get a solution is if someone is able to focus on your situation individually. You start getting 100 people trying to solve 200 problems together, and nothing ever gets done, and you just have a rant fest filled with threadjacking. See what Terms of Use says about threadjacking, rants, and trolling. It is more a problem to try to sort out the mess of that, than try to isolate the problems people are actually solving on the thread. Tell everyone on that thread to start a new topic that has a less obvious cause for others to threadjack, and more obvious cause to isolate their problem alone if they really want a solution.
CHUD's documentation is rather sparse as to how to get a common mortal to use it, and therefore I don't touch it. There are some features of it, I wouldn't run myself because they sound like they could cause more damage than good unless you know exactly what you are doing.
If you feel you have a power management or processor issue based on Apple's hardware test CD/Restore disk Startup Manager boot that came with your machine, take it in to AppleCare to have the machine repaired.
If you have an undetectable issue that appears even after an erase and install, it probably is the RAM that is improperly seated or has gone bad, or a logicboard issue that the test does not find.
Hardware test is documented here and how to run it for a MacBook Pro:
http://docs.info.apple.com/article.html?artnum=303081
And for most Powerbook G4s is here:
http://docs.info.apple.com/article.html?artnum=86287
An Archive and Install of an older system on a newer system does not necessarily work, and you may find that causes more freezes. That's because it attempts to install older versions of applications on top of newer ones, and may not always succeed, and you could be left with applications meant for a newer system mixed in with your older system that simply don't work.
Cache programs like Onyx, Macaroni, Applejack, Tiger Cache Cleaner, etc... can cause freezes if they attempt to clear caches when the machine is writing them because the cache files get corrupted. An Archive and Install won't clean up that mess.
So is your data backed up at least twice and do you want to try to isolate your issue? Or have I given you enough information for you to get started on your own?

"airport" process uses all of the memory an cpu

After I reinstalled my MacBook and updated to the latest version of Tiger (10.4.8) my airport network behaves very strange. When I boot my MacBook or disconnect/connect my Airport network a process called "airport" is consuming all the CPU and memory. It uses one core exclusivly and gows to 1,2 GByte of RAM (even more virtual Memory). This slows down the macbook to almost still and heats up the CPU.
The only thing I can do is to kill the process. Then everything works fine. But this is annoying.
It seems to make no difference if I use a wireless LAN or not. When airport is enabled then this bug occurs.

On this thread,
http://discussions.apple.com/thread.jspa?messageID=349
2852, people that have Check Point Software's
SecureClient are reporting the airport process using
~95% of CPU time.
I had SecureClient installed and I can confirm that
if you uninstall SecureClient, the airport process
works normally again. I don't know if this is the
only source of this problem, but if you happen to
have SecureClient, then you might want to uninstall
and confirm if this solves your problem.
Also I would be curious if anyone is having this
problem that has never had SecureClient, or any 3rd
party VPN software.
I can confirm that at least some of my problem with the "airport" process was related to VPN software. After uninstalling the Cisco VPN client, problems dramatically reduced. Interestingly, I still have the Checkpoint client installed, but only rarely see problems with "airport".

Process memory leak issue solaris 10

I have a process which has a memory leak issue. I ran this process on solaris 9 as well as solaris 10. When i run prstat command i get a different output for two. Funny thing is that memory leak noted in solaris 10 is much more than that in solaris 9 e.g if it is 1 MB in solaris 9 then its 4 MB in solaris 10.
What can be possibly causing this ? Is this related to kernel implementation on diff solaris ?

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.

OBVIOUS MEMORY LEAK iTunes about:10.6.3.25 (upgraded from 32 to 64) but iTunes*32 process is in memory. clicking on a song to play or right clicking it adds 5MB. Did 32 have this problem and didn't uninstall correctly or is 64 broken too.

OBVIOUS MEMORY LEAK
iTunes about:10.6.3.25
windows 64 bit Home on AMD64 HP G60 laptop
downloaded and installed "iTunes32Setup.exe"
saw the problem and uninstalled it
downloaded and installed "iTunes64Setup.exe"
iTunes about:10.6.3.25
now i see process "iTunes.exe*32
it is ok when it play song list
but ***** UP MEMORY when i click on another song to play. apparently it doesn't release previous player thread
OR,
if you right click on a song, the memory will blow up antother 6MB and won't release it...can do it all day long
-- until run out of memory and iTunes freezes...without any of my changes.
sooooo.. is it the uninstaller or is iTunes64Setup.exe mispackaged or do both have memory problems on AMD 64 ?

Unfortunately I was able to repeat the memory leak even with turning the Toolbar off. To replicate the problem, I was able to watch the memory leak each time I actively selected a new song with the iTunes open. I was able to repeat the leak with and without both Spotify and TuneUp Companion running and not running. The only thing I noticed is when both Spotify and iTunes were open, the memory leak from iTunes added insult to injure with Spotify which kept trying to sync up with iTunes local library which would crash Spotify as well. But I can confirm the memory leak is in iTunes 10.6.3.25 (looking forward to 10.6.4 fixing the problem).

Finding Process Memory Leak?

I have been tracking down memory leaks in a Java server-based application. I recently ran the application for several hours, and monitored memory usage with both JConsole and the Unix �top� command. I encountered some behaviors that I don�t understand.
With JConsole, I observed that the heap memory usage was fairly constant over time. The Code Cache space, however, gradually increased in size over the life of the test. I expected some increase as additional methods in the application were executed, but it seems that eventually the rate of increase would level out. It did not. Any ideas why that might happen?
The resident memory (as reported by top) increased significantly over the life of the test. Using pmap and jmap, I was able to determine that the heap space was increasing (even though JConsole reported that the heap was constant.) So, it seems as though the heap usage of the application is constant, but the heap usage of the process is still growing? I am using Java HotSpot VM for Solaris (1.6.0-b105).
Any suggestions or insight would be appreciated.

I'm not sure exactly what you're saying, but it sounds like this:
A tool that's monitoring the VM says the memory used by your objects is not increasing, but other tools say the memory the VM has taken from the OS is increasing.
Is that the case? If not, nevermind--I've misunderstood.
If that is the case, then it's totally expected. The VM doesn't usually give memory back to the OS. If it hasn't used up the amount specified by -Xmx (or the default if you didn't specify -Xmx), it's free to just keep grabbing memory from the OS, rather than running a full GC to reclaim memory that it has used for objects but that is no longer reachable.

Secd Process Memory Leak

Finding the secd process using 13GB of RAM was a bit of a shock. Watching its RAM consumption continue to increase, indicates a memory leak. Is this something anyone else has noticed? And any possible solutions?

Thanks - I think this helped, but will give it a day or two to see what happens.
My secd was over 32 GB the other day and the iMac wasn't quite its usual self. After restarting, secd's memory usage dropped away, but has been steadily creeping up over the last couple of days and was over 5GB this morning. So I tried dragging the Keychains folder to the trash and restarting.
The thing about dragging your keychain to the trash and restarting is, on logging back in you may be asked for a pile of passwords to all your mail accounts and your keychain will be empty!
I filled out all the requests for icloud passwords, but for the keychain to update properly, this took a while. I think what saved me from panicking about losing all my passwords, was going into System Preferences and signing into iCloud there. I was also requested to verify my iCloud login from another device (e.g., iPAD). I think this is what restored my keychain from the cloud.
Once the keychain had updated itself, I restarted the iMac again, and Mail returned to normal (no more requests for mail account passwords).
The only thing that wasn't restored after restarting was automatic keychain access to my time machine. I had to enter the password and save it to the keychain.
