OSX hanging intermittently

I recently bought a new 13" MacBook Pro 2.53GHz, I haven't even had it a month yet. I'm having a problem where the OS will hang intermittently. Let me explain.
I first noticed the problem when playing videos back with quicktime. All of a sudden playback would seem to stop even though I hadn't pressed pause. If I tried to click anywhere the computer would become unresponsive and I would get the spinning beachball (though I could still move the mouse). After up to a minute playback would resume but skipped forward, as if it had remained playing during the hang.
This doesn't just happen with quicktime is running. I've noticed I seem to be "allowed" one more click before the system hangs. I've tried to use this to my advantage by bringing up Activity Monitor, but I can't see any unresponsive or out of control processes. I've also noticed that if something is playing in iTunes, it continues playing throughout the hang.
Finally, when the hang is over, the system seems to play catch up, carrying out all the commands and mouse clicks I made during the hang.
This happens a few times a day. Hangs last up to about a minute. It's incredibly frustrating and I'm not sure how to go about fixing the problem. I've run a hardware test from the OSX disc and everything seems to be fine. Any suggestions would be greatly appreciated.
Cheers

HI and Welcome to Apple Discussions...
Might be a good idea to boot from your install disk and check the hard drive just in case.
Insert the installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger and later) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
Select your start up disk and click Restart
While you have the Disk Utility window open look at the bottom of the window. You will see Capacity and Available. Make sure you always have a minimum of 10% free disk space.
If you cannot boot from your install disk, try booting in Safe Mode

Synchronization hangs intermittently

Hi,
The synchronization of a couple of Analysis Services databases hangs intermittently. They generally hang on Thursday which is when there is a relatively heavy load on the servers. However the servers are high spec so there is not a high load percentage usage
of resources on CPU / memory and disk IO. The databases being synced which hang are around 15Gb in size.
I am also not able to receive any error messages.
Any help would be greatly appreciated.
Kind Regards,
Kieran.

Sorry that your New Year is getting off to such a bad start. Freezing can have many causes, and unfortunately the logic board can be one of them. Other possibilities may be a dying hard drive and software corruption.
Unfortunately, when I had logic board problems, it was definitely heat related. It would freeze after 15-20 minutes. If I set up a fan, it would go about twice that long.
Do you still have the original hard drive? If so, it may be getting long in the tooth. Here is a utility that you can download and run several times for free:
http://www.versiontracker.com/dyn/moreinfo/macosx/32454
This utility will give you more insight into the S.M.A.R.T. status of your hard drive than Disk Utility will.
What does the iBook do when booted from a disc? If it still slows and freezes, that would point to the logic board, as you are essentially bypassing the hard drive and the OS.
If you want to exert pressure on the logic board, here is an article that might help to apply it at the right point:
http://www.coreyarnold.org/ibook/
Finally, to eliminate all possibility of a software cause, you might want to try reinstalling the OS.
It would probably be prudent to back up all your data if you haven't already and keep it backed up. Until your iBook is diagnosed and fixed, there is always the danger that it could die at any time.
Sorry to not be able to be more encouraging.
Good luck!

After most recent update, Firefox keep hanging intermittently with "Not Responding".

After the most recent update, my Firefox browser begins to hang intermittently with "Not Responding". I have checked the extensions and plug-in like Java, all of them are the latest updated ones. Everytime I open a new site or click on links to load another page, it happens. Every single time.

'''is there a solution ''(temporary OR permanent)'' for this problem yet?'''
i tried '''EVERY possible alternative'''; even when opened in ''''''safe mode'''''' or when installed for the first time w| '''NO addons or ANYthing else''' but the '''original default settings''', still does the same thing.
mozilla people?? really?? no answer|feedback|suggestions, anything at all from u guys??
if it isnt a version (browser, OS, addons, etc) issue, what is it that separates us from the users not having the problem?
this is is very frustrating; h|e it's even more frustrating when there is no response from tech support. is it because there havent been enough people who have reported this same issue so there can be some interest & find a fix; OR is it that u dont know; OR that there is not & will not be any fix?
we cant continue being users if we cannot use it. it's really my favorite browser, but if it doesn't work & u guys dont have a fix for it, then users w| this same problem wont have any other option but to switch to a different browser permanently.
really mozilla??? nothing? a reply would be very nice...

Citrix the screens hang intermittently

We have an Oracle 9205 database running on Windows 2003 server.
We are web deploying our application using Oracle9IAS 10222; we are using the forms listener servlet including Developer6i Patch 16. The version of Jinitiator is 1.3.1.17.
When deploying this via Citrix the screens hang intermittently and users are forced to log out of citrix and log back in. Interestingly Oracle Financial's is running fine on the same box.
Pls, do let me know how to resolve this issue
Rgds,
Satya

The use of Citrix or any terminal emulation software with Forms is not supported. In most cases, it is determined that the cause of these types of problems are the result of the emulation software (Citrix in your case) and not Oracle Forms. It is recommended that you retest in a non-Citrix environment. If the problem is no longer reproducible you should then contact the Citrix vendor.
To be a valid, supported Forms user (client) the client machine must have a browser and Jintiator (JRE) install on their local machine. It is also required that the browser cache and JRE cache are stored locally.

Undetectable / Irreparable File corruption problems lead to OSX hanging

Hi,
I have a Samsung 500Gb 5400rp disk in my MBP17 ( 2007 ).
Certain files appear to be corrupted.. ie. you try to open them and the whole Mac freezes for 30-40 seconds.
Disk Utility cannot detect a problem, nor can Diskwarrior. I've tried repairing permissions, repair disk, rebuild HFS directory, scan files for problems.. these erroneous files don't get detected at all.
Just try to open one and Finder/OSX hangs for ages. File copy programs just hang for ages including Migration Assistant, Finder Copy.
So migrating from my MBP17 to my new i7 MBP17 doesn't work at all due to these "ghost" file.
Appreciate any suggestions for how to get my files across to my new MBP.

Delete the corrupt files before migrating.

Hangs intermittently

Happy New Year, everyone, from frosty Scotland. Mine's off to a lousy start. My four-year-old iBook G4 (OSX 10.3.9) has started freezing up on me, intermittently. Sometimes a reboot works (although it soon ends in tears); other times I end up at a blue screen. There's plenty of free disk space. I've reset the PRAM and run the disk first-aid. I've booted from the system disks. I've also had a good look on here for similar problems - have I fallen victim to the infamous logic board fault? Applying a c-clamp doesn't make much difference - the iBook hangs with or without clamping (although I'm not entirely sure I'm clamping where I should be).
The machine seems to work best when it's cold; I put in a good two-hour stint tonight before it started to act up. Anything?

FDB hangs intermittently and needs to be killed

Hey,
Do you guys have any idea what may cause this issue?
Sometimes when you publish a project, the debugger says it is ready, and Flash Player 10 is running, but its window never appears. When trying to compile again, the OS reports that the SWF file is locked.
The problem does not occur with Flash Player 9, but I have been able to repeat this issue with every version of Flash Player 10, using the external debug player on Windows. It happens intermittently so it is very hard to track down.
For what I know, Java (running mxmlc/fcsh/fdb) gets hung up. It sometimes starts working again if you kill every instance of FlashPlayer.exe ... ending the current debug session. It also starts to work if you kill every instance of Java.exe and try again.
I have not seen this issue when debugging by hand. The issue appears to be with the combination of Java and the Flash 10 player, and I have the feeling that it occurs because of something happening too quickly. Yes, I am using FlashDevelop, but it should not matter. FlashDevelop compiles the SWF, copies the result to the target directory, starts the debugger, then launches the external player when the debugger is ready. It offers the same commands I give the debugger by hand, so maybe Flash Player 10 has some kind of "warm up" period which sometimes gets the best of the debugger. Either way, FlashDevelop launches FDB, waits for the prompt, and offers commands.
Does Flex Builder use the same apps as the Flex SDK? Perhaps it does not occur because FlashDevelop runs faster. The problem is more likely to occur with bigger, more complicated files. Perhaps Flash Player 10 loads up, reports itself as ready, but still has to load up code. If for some reason this initialization stage takes a frame too long, FDB tries to talk to it as if it were ready, but its come through just too soon.
You can see more details about this here:
http://www.flashdevelop.org/community/viewtopic.php?f=6&t=4707
It's been over two years since I started having this issue. I stuck with Flash Player 9 for a long time because of it. Now that I use Flash Player 10 for all my projects, it feels like its time to try and figure out what's going on here. It's easy to pass the buck and say its a FlashDevelop problem, but that really is not what I am seeing ... and if FlashDevelop had to do something different, like add an artificial pause to wait for Flash Player to initialize, it would at least be helpful to know what needs to be done to negotiate the debugger without hanging it.
I appreciate your help and I don't mean to come across as confrontational if I sound that way. I'm just hoping to get down to a real answer and not assume that this is "just the way things are"
Thank you!

I have a few thoughts. For one thing, reading through the thread over on flashdevelop.org, some (and perhaps all) of the problems people encountered were due to a bug in the Flash player, which was fixed this past summer. (The Flash Builder record of the bug is here: http://bugs.adobe.com/jira/browse/FB-16153 -- but the bug was actually in the player.)
So please make sure you have the latest debugger version of the Flash player. You can get the latest version here: http://www.adobe.com/support/flashplayer/downloads.html
That is almost certainly the cause of the "WARNING: The Player that you are using does not support all fdb commands" message that member "elyon" described in his post on June 4, 2009. Hopefully it will help with whatever problems you are running into.
In another post that same day, elyon saw this output from FDB:
Adobe fdb (Flash Player Debugger) [build 4852]
Copyright (c) 2004-2007 Adobe, Inc. All rights reserved.
Waiting for Player to connect
Player connected; session starting.
Unexpected error while processing command.
For diagnostic purposes stack trace follows:
But apparently there was no stack after that message. If you can reproduce that error message, the way to get stack dumps to appear is to pass "-Dtrace.error=true" to Java when it launches FDB. This is a Java property, so it must be passed as an argument to Java, not to FDB. For example, if launching FDB from the command line, you can launch it like this:
java -Dtrace.error=true fdb.jar
> Does Flex Builder use the same apps as the Flex SDK?
Yes, but not in quite the same way FlashDevelop does. FDB has a public Java API that can be called by any Java app to control debugging, and that's what Flex Builder does, unlike FlashDevelop's approach. So, FlashDevelop and Flex Builder are using the exact same underlying debugger code; it's possible that there is some sort of problem with FlashDevelop's communication over the pipe, I just don't know.
You say you haven't seen this issue when "debugging by hand" -- you mean when using FDB directly? If so, then I suppose the Flash player version isn't the problem. I'd be interested to see a repro case that involved just FDB (perhaps reading commands from a file or a pipe if that's the easiest way to reproduce it).
There is nothing unusual about FDB's communication with stdin and stdout, it's pretty standard stuff. Also, it's all open source, http://opensource.adobe.com, so you can debug it if you want.

After installing Adobe Flash Player Plugin to view videos on youtube, mozilla gets hangs intermittently. Please help

I installed Firefox 23.0.1 and after that It asked me to install Flash Player Plugin to view videos on Youtbe. I installed Flash Player 11 Plugin and since then Mozilla started hanging/freezing intermittently. It hangs on those websites also where videos are not running.
I uninstalled Flash Player 11 Plugin and it works smoothly without it.
Please help

This is some standard guidance that addresses the most common reasons for Flash problems in Firefox:
(1) Make sure all recorders/downloaders that interact with Flash media are as up-to-date as possible, or disable them.
(2) Disable hardware graphics acceleration in Firefox and in Flash
(A) In Firefox, un-check the box here and restart:
orange Firefox button (or Tools menu) > Options > Advanced > General > "Use hardware acceleration when available"
(B) In Flash, see this support article from Adobe: http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_Solve_video_playback_issues
(3) Disable protected mode (Windows Vista/7/8)
See this support article from Adobe under the heading "Last Resort": [http://forums.adobe.com/message/4468493#TemporaryWorkaround Adobe Forums: How do I troubleshoot Flash Player's protected mode for Firefox?]

C application hangs intermittently on invoking Closehandle() function in Win 7 64bit OS

Hi,
I have a application which basically deals with network operations like begin session, send/receive etc. The application also has mutex create, request and close. Before terminating the transaction between the client and server, there is a call to Closehandle()
while clears that mutex that was created during initialization. (Mutex is released prior to close). During closing the mutex, in Windows 7 64 bit OS, the application goes to hung state intermittently. The same application used work without any issues in Win
XP.
PS: The C application is written in Visual Studio 6.0
Hence requesting for any thoughts to resolve this problem!!
Thanks in Advance!

Hi,
When application hangs, it needs to be restarted. Yes, this problems happens sometimes.
With respect to the anti-virus and firewalls, I had tried turned off firewalls and anti-virus but did not help!
This application basically acts as a network layer which is the bridge between client and server.
Below is the code snippet from the app which shows about mutex creation, request and close. I had configured ADPlus to the application to check on which line of the code the hang occurs and from that dump file could notice that the cause for the hang is
Closehandle() function.
Code snippet -
typedef unsigned long OSLMUTEXSEM;
extern OSLMUTEXSEM gsemCrypt;
void PASInitialize() {
char * pMutexSemName;
DWORD NTRC;
pMutexSemName = gsemCrypt;
oslRc = MutexSemCreate((char*)NULL,&gsemCrypt)); //Mutex creation by calling CreateMutex() function
oslRc = MutexSemRequest( gsemCrypt, SEM_WAIT_FOREEVER); //Request the semaphore by calling WaitForSingleObject() function -infinite //timeout
// some operation
oslRC = MutexSemRelease( gsemCrypt )); // release the mutex by calling ReleaseMutex function
void PASTerminate(){
oslRC = MutexSemClose(gsemCrypt); //calling Closehandle()function to close the mutex
WSACleanup();
From the dump files, it was noticed that the hang happens at the call MutexSemClose(..) function which in turn calls windows function Closehandle().

Switching graphics mode (9600m gt) - OSX hangs at subsequent login screen

Haven't been able to find anything on this. When I switch the graphics mode through the Energy Saver Preferences (whether from battery life to performance or vice versa), it takes me back to the login screen as it should, but the computer hangs there, sometimes for upwards of five minutes.
The cursor in the password field blinks but it takes no input. Plugging in an external keyboard makes no difference. The mouse pointer can be moved but clicking has no effect. After a few minutes, any inputs you've attempted to make rush back in at once and it works as usual.
I'm not sure when this started, but it's been happening since at least 10.6.5.

Hi there,
I am new to Mac and got my MBP i7 2.0GHz, 8GB, SSD, OSX Lion 10.7.2 last month. Have you guys got any solution for the slow rendering of Youtube video? On my new MBP it can only run at resolution: 240p.
The same video on Youtube at HD resolution runs perfectly on my old HP Core Duo laptop. Slightly dissapointed with Mac here. Tried to look around for solution via Google but no luck.
It seems like no one from Apple support provides any solution for this problem. Are there any support at all from Apple???

Essbase Server Hangs Intermittently - Urgent pls Help

Essbase Version - 9.3.3
Shared Services - 9.3.3
Enviroment - Windows Server 2003
We are in the process of migrating the users from Domain A to Domain B
There are around 15000 users across the board, out of which I assume there are around 250 users accessing the Hyperion Application.
Since the Domain Migration was started, We encountered Essbase Server freezes Intermittently.
Essbase Server goes down for about 10-15 Minutes and automatically comes back. No Error Msg in the Essbase Log.
Active Directory Migration was put on Hold because business had to complete their Month end Activities.
While we were working to find the RCA and identified that few users who were migrated from Domain A to Domain B appeared to be on Both the Domain and we figured out that it might be one of the reason for Essbase Server Hangs.
We had a Plan to Run the Update native Directory Utility to clear the Stale Data
Post Performing the Action our system was stable and didn't had system Hangs.
we also changed the shared services Cache refresh Interval to 24 Hrs in CSS.xml File ( Just to Make sure the Refresh happens Overnight)
Since the Active Directory Team had resumed their Migration Activies, we started Experiencing the System Hangs Issues again. server goes down for 5-10 min and comes back up
Please Input your Valuable Thoughts, Would Really Appreciate your Help.
Thanks in Advance.

Hi,
Thanks for your prompt response.
As mentioned, AD team have the filters on place, There is no issues with the User Access and there was no change in password after migrating the Domain.
I have checked the Display Session through Maxl and there is No heavy sessions.
As Stated earlier, we are unable to identify the cause regarding the System Freeze. All users access the application all of sudden essbase server hangs and it doesn't allow user to retrieve the data, nor allow him to access any application within Essbase and Planning.
After 5-10 Min, server automatically comes back.
Can you tell me if there is a way to track the system Hangs through Essbase Log without getting the any inputs from the users.
Assuming if the users sessions are heavy what makes the server hang and automatically resumes without intervention.
Shared Services Security Log display the following Error, Can you tell me if you had come across any such errors before.

SQLDeveloper hangs intermittently

I have been using SQL Developer for several years now and I have never experience a version which did not have issues with hanging and many times requiring me to kill the process.
I was very excited to see version 4.0 however I still have issues with intermittent hanging sessions.
Does anyone know if this is a windows issue, java issue, poor connection management....???
cheers,
j-e

Apparently the PL/SQL was padded out to 256 chars per line
This caused the JVM to run out of memory.
Unfortunately, I automatically assumed this was SQL developer hanging up.
What PL/SQL are you talking about? You didn't mention what you were actually doing when it hung up.

OSX Hang Issue

OSX appears to cause the application to "hang" if it is minimized for too long or sits in the background too long. It appears the system or AIR framework is placing the application into an idle state. Once you bring the application back to focus, it catches up and works fine. I am able to reproduce this on all version of Adobe AIR. Our application is a real-time application that requires constant connection. We've been able to find a work around where in some instances, simply playing a blank mp3 over and over causes the application to remain active.
I've created a bug case.

Too many dialogs get stuck on CPIC stopped,SAP hangs intermittently on prod

Hi All,
I'm having a problem with a production system in which users started complaining about getting the hourglass cursor intermittently, and this is happening from multiple different locations / networks. Around the time the problem occurs, SM66 shows many dialog processes in status "Stopped CPIC". The processes are from different users and processes.
I've checked the workprocess trace files, made sure there was no memory bottleneck with the gateway profile params, checked System log and oracle alert log, but cannot find any clues.
Could anyone please suggest some other places to look for clues or possible suggestions?
Thanks!

Netweaver 7.0, ECC 6.0
Oracle 10.2.0.4.0
AIX 5.3

Thanks for all your comments (points given).
The problem and solution was very interesting.
1. We found that an external AS400 system that communicates with SAP was somehow sending the IP address in EBCDIC format, which looks like strange characters. We saw the strange characters in the Gateway NI/Hostname buffer. During each hang situation, we saw these special characters in the Gateway trace file. The Gateway was attempting to resolve the IP address for the strange EBCDIC characters, but the EBCDIC characters were actually the IP address itself when converted from EBCDIC to ASCII.
2. As per SAP, we added the strange character hostname/IP to the /etc/hosts file with the correct IP, and the hangs stopped happening.
3. After these 60 second hangs stopped happening, we were still getting 10 second hangs every 3 hours.
4. SAP found that the Gateway logging option was causing the 10 second hangs.
5. SAP is working on a kernel fix so that the Gateway doesn't hang in these situation. We have the workaround in place for the time being.
Thanks,
Ian

OSX hangs during boot or install

Hello all,
I'm writing this because I'm not really sure where else to post this at to get an indepth answer. Currently I have a dual G4 450mhz AGP PowerMac that I bought used. When I purchased it, it had 768mb of ram and the only thing it didn't have was a working hard drive. After putting in a new hard drive the system worked great when i intially installed OS9 and later OSX for fun.
However I had to remove the 768mb of RAM because a client PC needed it and that took priority over my dual G4 at the time. Just the other week I purchased 2 x 256mb of RAM from Omni Technologies (omnitechnologies.biz) which guarantees working ram for specified Apple systems.
Upon receiving that ram and installing it, I powered on the G4 only to find it would "hang" when booting OSX (10.3.9). The symptoms are as follows: When powering on I hear the normal chime and the white screen with gray apple logo appears. Seconds later the spinning progress indicator shows up spinning in circles as OSX is booting. However after about 5 minutes with no DVD/hdd activitity, the system then hangs. The gray apple logo changes to a gray 'prohibited' logo. It's the logo of the circle with the slash through it. Like the kind you see over no-smoking signs.
I figured the hard drive was messed up and I decided to reinstall OSX cleanly. However when I booted from the CD by pressing 'c', the EXACT SAME symptoms above happened. It was at this point I started getting really worried. So I decided to remove the hard drive temporarily and boot from the CD just to make sure it really was booting from the CD. Unfortunately the exact same symptoms happened.
Out of desperation to make sure that my hardware was OK, I decided to install OS 9.2.1 which installed and WORKED perfectly. I also installed UbuntuPPC and Slackintosh versions of linux which also installed and worked perfectly.
The issue appears to reside with OSX. I've borrowed friends cd's of 10.2-10.3 and all of them will NOT install. They start to boot from the CD, but never even make it to the first window.
Help!!
Brad

Actually trying one stick in each individual slot was one of the first things I did. Unfortunately that did not provide a resolution for me.
Thanks for the links regarding the broken folder/prohibitory sign. I read those and they made mention of resetting the nvram and pram. I just did that a bit earlier today but logging into the open firmware by pressing Option-Command-F-O and typing: reset-nvram; set-defaults; reset-all.
Upon the reboot and after I plugged the hdd with OSX on it back into the system, the resolution was a bit off as I figured. But this time there was no progress indicator. Instead only the gray apple logo showed and there was no response from the hdd or cdrom drive.
I also noticed that the USB mouses red light went out within the first 45 seconds of booting. I swapped out keyboards and mice and the new ones did the same thing as well. I also tested the memory in an imac I have and OSX that is installed ont heimac works gerat with that stick of memory. I'm leaning towards the fact that the memory I have is fine, being that it was ordered from a company that specifically guaranteed it to work on macs of all kinds.
Any other thoughts or ideas?
