Activity Monitor Freezes Intermittently

Starting in 10.5.1 and just lately in 10.5.6, Activity Monitor intermittently freezes even when there is no indication of heavy usage.
Strange things happen eg. the scroll bar may still go up but not down, the program menu appears then disappears. I usually have to Force Quit even though there is no indication of Not Responding. (Sometimes I can quit from my Dragthing Process Dock.)
I am not sure if this is related to the presence of "crawlers" eg. VirusBarrier Real Time Scanner. There is no indication that they have excessive usage.
What can I use to monitor the Monitor?

HI,
Delete the VirusBarrier RealTime Scanner. You do not need anti-virus software on a Mac. A/V software on a Mac will manifest itself if all the symptoms you are having.
This utility can remove the application and all associated files;

Activity Monitor Freezes

Since installing Leopard I have been getting Activity Monitor freezes. I have to quit the application and relaunch to get it going again. Happens every 30 minutes or so.
Anyone else have the lockup? Any clues to fixing the problem?

Welcome to the Mac world. Basic Mac user rule: don't move Apple apps or utilities from where Apple installs them. Basic problem isn't what you ran into, but future updates won't occur because the installer ignores anything not in the correct location.

Activity monitor freezes and shows no processes

I've been having a recurring problem lately. I have two large Numbers files with lots of cell references. When working with these files, my MacBook's brain seems to be melting: operations as simple as changing worksheets can take a few minutes, editing cell contents can take several minutes more. Copying and pasting is a "set it up, make some lunch, come back and check" kind of operation.
The performance was so remarkably bad that I thought I should open up the Activity monitor and see how much of the CPU Numbers was using. However, I found that whenever I try to open the Activity Monitor, no processes are listed and the monitor hangs indefinitely with the swirling "waiting" pointer. No processes ever show up, no matter how long I wait, and the monitor is frozen with the "waiting" pointer. If I try to force quit the process, it is listed as "Not Responding".
Any suggestions for what might be going on here and how to fix it? Could the Activity Monitor and Numbers issue be related? I'd like to troubleshoot the Activity Monitor first and then move over to the Numbers forum if necessary to figure out the problem there.
Thanks very much,
Adrian

Had to do a disk repair from the Mac OS X install disk.

Activity Monitor, Memory and Freezes

I've had a few Logic freezes recently so I open Activity Monitor to try and find some info. Firstly if the CPU use and threads next to Logic Pro keep changing is there a chance that Logic will unfreeze if it's been stuck for say over 5 minutes?
Also I'm trying to see how near I am to the memory ceiling. I've got 32 GB in my MacPro so it's not a shortage of RAM more hitting the single app limit. I don't understand the relationship between "Real Memory" and "Virtual Memory" as regards the single app limit. Logic has just crashed and the associated readings are Logic Real 2.13GB Virtual 3.88GB, VSL Daemon Real 7.02MB Virtual 867MB, VSL Server 2.35GB Real 3.31 GB Virtual. ousiad (is this East West Play plug-in?) 816kb Real 2.57 GB Virtual, Vienna Ensemble 882MB Real 2.5GB Virtual. Total free memory is 20.11GB.
If someone can help my understanding this would most be welcome!
Thanks
Julian

"Virtual 3.88GB" - That's the one that kills your Logic app.
You can read a lot on the forums that Logic has this limit of around 3.5GB of memory that it can allocate. I want to point out two things from my experience.
1) This limit is about the "Virtual Memory" not the "Real Memory".
2) When you get close to that limit, Logic just crashes. You would figure that it might give you just an alert box with a memory warning, no - poof - Logic is gone.
A few more things.
* Keep your Activity Monitor open and be very careful when you go across the 3GB "Virtual Memory" line. Every additional Plugin could push you over the edge.
* Besides loading additional instruments, there are other factors that you should be aware of. i.e. Apple Loop Browser. If you have a big Apple Loop library and you make a search on all loops, you can see in the Activity Monitor that such a search could require a few hundred MB of additional Virtual Memory. That's enough to cross the line and crash Logic. Believe me, it took me a while (and a lot of frustration and restarts) until I figured that out.
So why the difference between the "Real Memory" and "Virtual Memory" number. I seems that this leads into hardcore programming voodoo,aka "I have no idea". One observation I made is the impact of the graphic cards. Usually the Virtual Memory number is about 300-500MB bigger thatn the Real Memory number. When I changed my 2 graphic cards to new ones with more VRAM the difference between the Real and Virtual Memory number grew to 1GB . Don't asked me how long it took me to figure out that relation. All I saw was that I couldn't load big Logic Projects that I worked on before with no problem.
Bottom line:
The more stuff you load into Logic, the closer you have to monitor Activity Monitor and save more frequently.
Think about how often you read forum posts that Logic is completely unstable and crashes all the time. I bet that a high percentage is related to user hitting that Virtual Memory limitation.

Mail slows to a trickle and then freezes - Activity Monitor shows all OK

I've been having this issue recently where I will be typing an email and I notice I begin to outpace Mail's ability to display the letters I am typing until finally it stops altogether.
At this point Mail becomes almost completely unresponsive. I can still click on the email modal window in question and move it around, but I can't access the Mail main window or click buttons and the menu bar doesn't come up.
The weird thing is that Activity Monitor appears to think that everything is kosher. No CPU spikes, no memory issues, no excessive writing, and no network log jams. So it actually never displays the message "Application Unresponsive" as one would normally expect from an unresponsive app.
The console messages that appear at this time are:

I thought F4M was Flip 4 Mac, but I have no idea why that would be tied to a Mail process.
Any thoughts or ideas would be welcome on troubleshooting this!
Thanks in advance,
Richard

Hello Richard:
I have never experienced what you describe so I am fishing a bit.
Try rebuilding the mailbox(s).
If that does not help, trash the preference file (com.apple.mail.plist) and restart.
One other thought - I have read that Mail will have strange behavior if the mailboxes are too full. However, I have no clue how +"too full"+ is defined.

MacPro Quad Core 32g Ram running slow Logic using only 9g in Activity Monitor

Well its taken a while, but this is my first foray into the world of forums! I'm so hacked off with this regular problem and havent been able to find anything anywhere to solve it i thought i'd see if anyone has any similiar issues and maybe even a solve to it.
So.... im an orchestrator and producer and after my mid 2008 Macbook Pro with 8g ram started freezing up i invested in this 3 years ago -
Mac Pro 2x 2.4ghz Quad Core intel Xeon and stuck in 32gb of lovely Crucial RAM and 3 seperate internal 1TB drives with one for operating system (10.6.8), one for Audio recording/saving and one for all my sample libraries.
32gb ram - should be enough i thought!
So i regularly run at least 30 VI's - Ni The giant, Spitfire Orchestral librabies (say 12 string instruments up to 0.69g per load) LASS strings, plus perc STYLUS, ABBEY road drums, Trillian basses (acoustic/electric), ominisphere etc etc. So pretty hefty sample instruments. But theyre sooo nice!!
In addition, the 32 bit server will come alive (NOT! So unstable i find) with my Waves plugs etc.
Looking at ACTIVITY MONITOR however i might be not touching 9 gig (and sometimes even less) of usage for Logic, and only say 800MB for 32 bit server and have NOTHING else open - and what do i find .....
- Mouse lag and cant really do anything with the mouse whilst playing the track - cant adjust volume - too slow, zooming problems
- Takes a good 2-3 seconds for track to stop playing
Dont get System OVERLOADS so much, its just that the system goes REALLLLLY slow.
What ive tried- - -
- Running Mountain Lion off another drive (havent had time to install it and wanted to be sure everything worked etc)
- Tried all audio prefs - large/small buffers/threads etc and yes i am on 1024.
in a nutshell how come with 32g RAM everything is so slow when barely using 10g of that???????
I dread getting to the end of a project cos i know im gonna be freezing so much, but with so much editing all the time for the orchestral parts i need everything unfrozen and working.
Sorry if this is long winded but wanted to describe what im experiencing.
Any feedback most welcome! Thankyou in advance.

The 32bit server is a pita: Waves v9 are 64bit compatible (they run fine). 32 bit VI's can be run outside Logic using Vienna Ensemble Pro (see later)

Some of these VI's are extremely CPU hungry: Abbey Rd drums for example, really do hammer the CPU. What does Logic's Performance meter show in the way of CPU load. What does Activity Monitor show regarding CPU load?
With 32G of RAM, this should not be the issue, but you might have general CPU problems (see above), and you may also have Sample disk streaming limitations if all the Loibraries you mention are on the same drive. How does Activity Monitor look regarding disk access? You might find it helpful to add a second drive and split the sample libraries across 2 for faster disk access.
I presume that you have plenty of free space on the System drive?
Logic can get sluggish if the Undo info gets way too big, and also if there are loads of regions in the Arrange: check Options:Project Information.
Many are finding some benefits (me included) by running the VI's in Vienna Ensemble Pro:
Better CPU load distribution than directly in Logic
"Persistant Samples": they can remain loaded whilst you switch Logic Projects
Logic is effectively running much less itself, so generally flies.
32bit Plugs hosted separately in VEP so no 32bit Bridge issues in Logic
Something to consider,though perhaps not yet, would be setting up a Slave computer using VEP.

Tips on managing Activity Monitor?

I'm getting a new MacBook Pro next week. Until then, I'm running my current machine off an external hard drive. However, it's very hard keeping it going. It sometimes works fine for a while, but it always freezes eventually, apparently a victim of insufficient memory.
I just wondered if anyone has any tips on key processes I can close in Activity Monitor to keep it going? I've freed up some memory by using Safari and TextWrangler instead of Chrome and Dreamweaver. In fact, the only programs I have open at the moment are Safari, TextWrangler, MAMP PRO, Activity Monitor and Finder.
Surprisingly, Finder appears to be another major memory hog; it freezes all the time (though not at the moment).
Thanks.

Activity monitor keeps hanging and hanging..

Hi all there!
I've the problem that this application just wont work, whatever I'm doing if I start the Activity monitor the application opens nothing happens and a few seconds later the bleachball of death appears and the application just freezes and becomes unresponsive, I've to force the exit to close the app
any idea on how to get rid of the problem?
here's the report of the console

@dovn
I red the page, the fact is that I'm not able to figure out what's causing the problem
the application freezes in any occasion, even when the mac was just turned on..
could it be that it's somehow in conflict with an other process running in background?!
Sometime conflict occur, but I doubt with Activity Monitor.
I was thinking of maybe I could just insert the OSX application disk that came with the macbook and trying that way reinstalling the app?!
Did your machine come with Snow? Anyway, I would do a repair install of Sno by installing Sno over Sno as in an upgrade install. Such an install, while usually very safe, still is an install so be appropriated backed up if you proceed. You will need to reinstall 10.6.1 and 10.6.2 after the repair install. Do so using only the [10.6.2 combo updater|http://support.apple.com/kb/DL959].This approach might fix any corruption leading to your problem.

Active monitoring logs randomly clearing after CU5

After performing the Exchange 2013 update to CU5, we have been noticing that some of the active monitoring logs are randomly clearing. Specifically the Throttling Config, Responder Definition, Monitor Definition, Probe Definition, and Maintenance
Definition logs. The only correlation I can find is in the Startup Notification logs I see an event every time the logs are cleared starting the Local endpoint manager. I looked back prior to CU5 and this event occurred infrequently, and accompanied by a handful
of other startup events, now it seems to be running by itself intermittently. It isn't happening at any consistent time or date range. Sometimes we will have 2 in one day, other times it will wait 2 or 3 days to clear. Default behavior even if the log
is full would be to overwrite old logs rather than perform a log clear, but I'm looking at the log and even after a full days worth there's barely 100 events in any given log. I reviewed the logs and there's no indication of trouble, no
errors or warnings. Is anyone else seeing this behavior on exchange?

Hi Theantioch,
From the release notification of Exchange Server 2013 CU5, CU5 includes a Managed Availability probe configuration that is frequently restarting the Microsoft Exchange Shared Cache Service in some environments. The service is being added to provide
future performance improvements and is not used in Cumulative Update 5. More information is available in
KB2971467. As of Exchange Server 2013 Cumulative Update 5, this notice and the frequent restarts of the managed availability process are
considered not to be a concern. Our issue could be related to the frequent restart. And we can safely ignore the problem. Thanks for your understanding.
Regards, Eric Zou

Notification Centre Freezing Intermittently

Hello All.
I have been having a problem with notifications on 10.8, where the notication window freezes (mouse turns to beachball when over window) and the notication menu item does not work.
Apart from restarting, how would I force the notification system to restart.
Most recently, An App Store update notificationappeared, and now that corner of my screen is unsuable.

I, too, am having this problem. I'm running a 2010 Macbook Pro (15") and just to be sure, did a complete backup of my stuff, reformatted the computer, installed Mountain Lion fresh, and manually replaced my apps (reinstalling them and copying over their preference files) and personal data. I have a system lacking any corrupt preferences, cruft, or anything else that I can tell might impact this. I've run OnyX to deep clean all the caches and repaired permissions. The disk is reported as healthy with no problems by Disk Utility.
Notification Center will (99% of the time) hang if I ever try to open it after the computer sleeps. In addition to notification center hanging, it will also cause the Dock process to hang as well. My mouse will be unable to interact with any windows (no clicking or ablity to scroll). Thank goodness for Alfred, wherein I can quickly launch terminal commands to restart things. As an aside, is there no keyboard shortcut to kill a process in Activity Monitor? Opening that, I can use the keyboard to shuffle through items, but since I can't click on anything, I can't seem to kill any processes.
If I manually kill Notification Center, I can finally interact with windows again, clicking, scrolling and typing all work fine. Unfortunately, I still need to kill the Dock process. When I run sudo killall Dock, instead of responding instantly, as it normally does, it can take up to 5 minutes before the dock process restarts, so I'm thinking there's something fishy going on betweeen NC and the Dock when invoked after sleeping. I'm not an expert in this stuff, though, so maybe Apple can take note of this.
Again, this is all happening on a clean install of 10.8.2. I seemed to notice the problem [i]after[/i] I linked my Twitter/Facebook accounts to OS X, but can't confirm that. Hiding the share icons and unlinking my accounts seem to make no difference. It would be interesting to know if all the people here have linked social networks and share buttons or not.

Activity Monitor issue

I have been using Activity Monitor more lately to stop Norton anti-virus automatic scan from scanning my Ipod because it takes too long to check it and usually ends up freezing when doing it. But just recently Activity Monitor has just stopped working, I click on the application and it bounces a few times in the dock and does not start up. How can I fix this issue?

just to sort out the easiest possible cause: have you verified that it not just the acitvity window that has gone missing? If that would be the case you would see Activity Monitor in the Menubar and could choose Window -> Activity Monitor or press  1 to get the windows back.
If that is not the case, is there a relevant (crash) log entry in the console?

How to read activity monitor????

My system keeps freezing up while using garageband. I've noticed on activity monitor that the "green/% user" bars are peeked, while the "red/% system" bars are relativly low. First: How do I interpret these colors? Second: what can be causing problem? I've posted on "garageband" link, but no help interpreting activity monitor was offered. Any help - VERY appreciated!!!!!

the colors, such as green, indicate who is running the process. User processes are those application you have started or have running. These could include appliactions such as Firefox, Safari, Word, or Garageband.
colors such as red are programs the system has running. These could include automount, File Sharing server. In general applications used by the system.
So when you are looking at garageband in activity viewer. From the pop-up menu, select My Processes. Next to it, in the filter field, type in garageband. This way the only process you will be watching is GB. See how much of the CPU it is using, as well as how much memory it is taking up.

Activity Monitor shows Compressor functions as (Not Responding)

Hi Forum
I have noticed in Activity Monitor that I repeatedly get these messages in red:
CompressorJobController (Not Responding
qmasterqd (Not Responding)
CompressorTranscoderX (Not Responding)
ContentController (Not Responding)
Qmaster Task Service (Not Responding)
I have been force quitting them and then they continue to show up even if I don't have compressor open.
I compressed a 40min HD at 800kbs last night - I woke in the middle of the night thinking it would be done and it was only half way done. I opened Activity monitor to see what was going on. It said that the these functions were (Not Responding). But i noticed activity in the cpu column and in the threads and processes window. I decided to see if it was really hung. I let it go till morning. I finished in about 8 hours. Can this be true?
I am on the top of the line 17inch Macbook Pro. It seems like there are some anomalies that I don't understand. Should I disregard these recurring functions that say they aren't responding?
thanks
david

Here is some investigation I did, maybe someone can use this!?
While everything is running and suddenly all **** breaks loose, or rather just freezes in time.
Open Activity Monitor and select CompressorTranscoder and click the Inspect icon, you will get the process details and check the 'Open Files and Ports' tab.. There is where you will find all the files this process needs!! Here is the issue! you will notice some temporary and cache items,. open the terminal and using commands navigate to those file locations and Voila!! you see those files dont exist!! thats why this service has hanged.. The apple team needs to figure out how these files got closed without compressorTranscoder knowing about it!! BUG BUG BUG!!!

I can't run activity monitor application. It just processes with the multicolored disc spinning, but does not open.

I can't run activity monitor application. It just processes with the multicolored disc spinning, but does not open. It also won't close without using "Force Quit." When I access it in Force Quit it's listed as not responding. I am getting the messase that my start-up disc is full, but I can't assess the status without using the activity monitor app. Thanks for any assistance you can give. -F.J.

Welcome to Apple Support Communities
If your hard drive is full, you have to delete files. Open Finder, search in all your user's folders and delete files that you don't need, or move them to an external drive.
When the hard drive is full, OS X works slow and applications may freeze, so I wouldn't be surprised if this is the reason why Activity Monitor isn't working

Running 10.8.3 on an Intel iMac 27'. The Finder keeps grabbing over 100% of the CPU which seems to stop me from opening any folders. Only quitting the Finder from Activity monitor resets it to normal. Any ideas?

Nope, I don't have a "/Users/charon/Library/Mobile Documents" directory, let alone anything underneath it. Is that like an iCloud thing or something? I tend to avoid the Apple-supplied services when I can (I don't use iTunes either unless I can help it).
As an update, as of about two days later this problem seems to have solved itself. Possibly sleeping and waking did something to it (though that seems unlikely given how many times I rebooted), or else there was just some long-*** kernel process that finally worked itself out. But my system CPU is back down to normal and the cursor freezes are gone.
??? it is a mystery! ???
