Keychain Hangs the System

When I got my brand new iMac with Retina Display I decided to use the fresh install of Yosemite and just transfer my files over thunderbolt from my laptop. I figured this would clean things up. But I've been plagued with issues since getting this computer -- issues I haven't seen on any Mac I've ever owned. I've had to clean restore this machine 4 times already.
Here's what happens.
At some point after being fine for a week, Keychain decides it's process is going to hang. This shows itself in two places:
Safari hangs on autofill to the point that I have to disable autofill entirely
Authentication in System Preferences (clicking the little lock) returns an "Authenticating" message next to the icon but never opens the password dialog
I'm not sure what to do. My system isn't abnormal and I'm not screwing around in the keychain at all. I've tried:
leaving iCloud Keychain access turned off,
tried it on,
manually transferred Keychain info from my other computer.
Keychain repairs don't do anything... thinks it's all fine.
But I can't use autofill (not a big deal since I use a 3rd party password manager anyway), and I can't unlock menus in System Preferences... and that's the biggie.
Has anyone else run into this or have any ideas?

Of course not, I've been hacking at OSes long enough to know that conflicts from Library preference and support files are not good. I allowed every transferred app to reinstate its Library preferences on first run.
In any case, I did some more digging and it seems CloudKit was caching some inconsistencies. Removing its caches fixed the issue as described in this thread.
Glad I know what the issue is now.

Hard drive works, but when plugged in hangs the system

First of all, since this is not a Linux-specific problem I'm not sure this is the right place for this post.
Anyway, for the past few years I've been using a 250GB IDE hard drive mostly to store backups on. For quite a while it worked fine, but when plugged in again after being removed so I could clean out the dust in my PC it didn't work quite right anymore. It caused the system to hang and gave error messages remniscent of those detailed on this page. After some fiddling it worked OK for a while, and then one day it randomly did this again. I took the ribbon cable out, then the hard drive, and realized one of the pins was pushed in (at the time I thought it was broken). After some reading I decided to sacrifice a ribbon cable. What I did was yank a pin off of an old DVD drive that doesn't work and shoved it in the cable where the short pin was. I made sure it was seated well, plugged in in, and hoped for the best. To my delight it worked without a hitch for maybe a year or more.
And then a little more than a month ago we had lightning strike a power line outside of our house and it fried my motherboard. I now have a replacement board, but after all of the taking apart and moving around and stuff, the hard drive is back to its old antics. The pin-in-the-cable trick wasn't working anymore. After I realized that the pin wasn't broken half-way but rather pushed in, I grabbed some needlenose pliers and pulled it out. It now will plug into any ribbon cable just fine and the computer recognizes it, but it's slow at POST and hangs the system when booting the OS, whether it be Linux or Windows. Knoppix CDs boot just fine, although slower. S.M.A.R.T. sees no problems.
Basically I'm wondering 2 things. First of all, is there anything I can do to get around the hangs? And second, I'm considering buying an external hard drive enclosure for regular 3.5 inch hard drives and using it as an external USB drive. Since the drive does still work and I can add/remove stuff while booted in Knoppix, and the main issue seems to be my system hanging, I figure, maybe, I can just plug in the drive when I need it after the computer is already booted up and it will work fine. Does this sound like a reasonable expectation?

What you hear may sound like it's the hard drive, but it's really an electronic type of noise. Same with my PB. Try what BGreg said, and wait for the drive to spin down - you'll still hear the noise.
There was a thread about this issue several months ago, and IIRC the conclusion was that it's a normal noise, and that you should just ignore it if possible.
If you must make it quieter, set processor performance to the lowest setting in Energy Saver preferences. But it's not going away completely.

Printing TIFF files hangs the system, is there a workaround?

When printing large tiff files (e.g., exported layout images from CAD) the system becomes unresponsive and it takes time to print. Even after the image is printed, the system works very slowly.
It seems to be a bug, or is there any workaround to prevent the system to hang?
Thank you, Jan

There are two similar bugs:
The LPC+crop bug started with ACR 6.1 and was fixed in 8.2.
The LPC mystery bug started with ACR 7.3 and was fixed in 8.6.
Both bugs cause repeated thumbnail extractions in Bridge on some images with Lens Profile Corrections enabled.
As you are on ACR 6.7 it can only be the first bug. The only workaround I know is to ensure that the crop does not touch the edge of the corrected image. A few pixels gap will do it. Also, it helps to keep less images in a folder--but this can't be avoided when using Collections or Finds.
I'd imagine that Adobe won't fix CS5 just for this. Presumably there's something in the smallprint which admonishes them from responsibility after the shelf life of the product ends. To be fair, it's not like they fixed it straight away in CS6, unlike the Bridge CS5 database bug (thanks, Adobe). They were only able to reproduce the fault in summer 2013.

OVM Linux service hangs the system reboot

System:
Oracle VM Manager
Version: 3.1.1.305
Hello everybody,
I have the script to start the node manager on system reboot on run level 2. After rebooting my VM I can’t log on with putty anymore. So I opened the console with my RealVNC from OVM Manager and rebooted the system and I can see this service hangs the boot process.
I was able to open the boot menu in console but I don’t know how to select option “e” (edit the commands before booting) or “c” for command-line.
Is there any other way to stop this process ( control-c doesn't work either) and continue booting the system?
Any help will be appreciated.
Thanks,
Alex

Hello
If the VM is paravirtualized, then you won't see the grub to press e and edit the boot option.
What you can do, is change the boot from disk to network and use the network process you used to install, but go to rescue mode.
Does this helps?

QRFC jobs hangs the system

Hi,
We have a problem with QRFCs. We created 50 queues programmatically and run some job in each queue. If the job is run directly, it takes only 2-3 minutes to finish. But when this is scheduled in the queue, in the queue monitor (SMQ1) it shows the process is running. Most of the dialog workprocess gets used up and the system hangs. We can't even login to the system. The situation is the same even after 24hrs and no actual work is done.
I feel some problem with system settings. Looked in to some notes like 527481, but most of their suggestions regarding profile parameters are already the taken care.
In the system log (SM21) I can see lots of these errors 'No APPC block received'.
Please help..
Regards
Ajith Chandran

The change or inclusion of these parameters worked for us.
rdisp/wp_ca_blk_no = 2000
rdisp/max_comm_entries = 1000
rdisp/appc_ca_blk_no = 500
rdisp/max_arq = 1000
rdisp/tm_max_no = 1000

Windows update hangs the system after shutting it down

I have shut down the system while it was updating the system (Microsoft update). Now it hangs, telling that update nr 11 of 13 is busy
what should I do?
The os is windows 8.1

The system should be able to start an automatic repair.
First of all you should perform a complete shut down of Win 8.1 as described in this document:
http://aps2.toshiba-tro.de/kb0/TSB2B03EY0002R01.htm
After that you should reboot the notebook…. Usually the system would start a self-repair procedure which should fix the update issue.

SetWindowsHookEx(WH_JOURNALRECORD) is hanging the system on Windows 7 and Windows 8

I'm in the process of porting an old application that uses the Journal Record Hooks to record macros to Windows 7/8. I've done everything that needs to be done to make this works, that is :
set uiAccess=true in the manifest
sign the application with a valid certificate
execute the application from the Program Files folder
After doing all this, the hook install correctly and it works. However, sometimes, for no apparent reason, the system freeze in a weird way : my keyboard and mouse inputs doesn't reach any application and the only thing I can do is ctrl-alt-del or ctrl-esc,
which uninstalls all system wide hooks and thus, unfreeze the system.
I've added some trace logs and I've discovered that when it happens, the SetWindowsHook function returns a valid hook handler, my hook function is called, but only once and then the system freezes. I've actually cleaned up my hook function and the only thing
I'm doing is return 0.
Is this a known issue or am I doing something wrong?
Thanks

Hello subbtract,
>> the SetWindowsHook function returns a valid hook handler, my hook function is called, but only once and then the system freezes.
Will your tested machines be fresh which I means there is other application installed except yours? If possible, I suggest you could make a test with conditions above, if the system is still frozen, this should a issue of system about the SetWindowsHook
function. You could post it to:
https://connect.microsoft.com/VisualStudio
While if it works with a fresh machine, this issue could be caused by features of installed applications. You could then compare worked and not worked to check the difference.

Opening Docs in Word Hangs the System

I'm running OSX 10.4.11 (actually, it's OSX Server, but none of the other workstations are affected, so I think we can ignore that for now) on a MacPro 2 x 2.6GHz machine with 4GB of RAM.
Here's the problem. Whenever I open Word (11.3.8) or Excel (11.3.7) and try to open a document (whether by selecting Open from the File menu, clicking on the button in the toolbar, or simply starting the application up from scratch), instead of the lovely Open Dialogue popping up, I get the Spinning Ball of Doom. Then the entire system hangs—I can click on other visible applications and the menu bar changes, but those apps are hung too; I can't access any of the menus, the Dock is inaccessible, and attempting to force quit from the keyboard does nothing. And, of course, because this is the server for our small office network, the entire network comes crashing down.
I've reinstalled Office. I trashed the preference and cache files. I ran Disk Utility and fixed permissions. No go. Help!
Again, I am fairly sure that this has something to do with Office's proprietary Open dialogue box, because I can fire up Word and—if I've done so by double-clicking on a document in the Finder rather then on the application icon—edit and even save. I can open documents in non-MS applications just fine. (And, as I said, I can open and save Office documents on the other computers on the network.) But open a doc in Word or Excel (or, presumably, PowerPoint), and boom—everything comes crashing down.
Anyone have any ideas???

I'm still struggling with this.
I can open documents in non-MS applications. (I'm on the affected workstation now, and have just opened docs in Preview, Apple Pages, and GoLive CS.) I can open the MicroSoft Office Project Launcher, so the problem doesn't seem to be that particular application, but when I try to open a document from Word or Excel, the whole system hangs. Which brings down our entire LAN. Which is a big drag.
For now, we use the other workstations for anything that'll involve an Office application. But we would like to use this one as well!
Again: it's a MacPro 2 x 2.66 Intel with 4GB of RAM running OS X Server 10.4.11.
Help?

Kodi hangs the system

I am searching solution for this for about a half year.
XBMC/KODI freezes whole system (it doesn't respond to any input, even http or ssh stops to respond), sometimes whein it starts, often when searching for new files in music folders, sometimes totally randomly. Here is the last debug log. It's from clean install of kodi with deleted .kodi dir.
I am running a fully updated Arch Linux x86 on old Pentium 4 computer with 1.5GB RAM and AMD Radeon X1650 PRO using open drivers.

i'm having the same exact issue with a newer pc (intel i5-2400, 8GB ram, nvidia geforce gts 450 with nvidia drivers) with arch64
my last log is here http://pastebin.com/4q49xy9j and it hanged while automatically scanning video source..
actually i'm running arch64 also on an older laptop, with different hardware, but the os is configured exactly in the same way, and xbmc/kodi works flawlessly..

CS6 caching hangs the system every time I preview

I have recently put together a system specifically made for AE but have found that the way it caches has seriously slowed down my entire workflow.
Every time I hit RAM preview, no matter how small the project, AE hangs as it "initialized background processes" and then stops at frame 2 while the media cache HDD churns and churns, sometimes for 30 seconds. Eventually rendering starts and it is blazing fast, but it makes previewing quite a hassle to use.
This behavior is directly linked to multiprocessing, and if I switch it off there is no wait before rendering begins, however this runs counterintuitive to my whole set up and slows down my work considerably.
It seems that the way AE CS6 does its caching is with small 128KB files that completely throttle the mechanical hard drives and really make this feature unusable.
Short of cancelling multiprocessing, does anyone have any suggestions?
My search on the internet has yielded similar complaints:

Syncserver.exe hanging the system

Do not know what is happening but now on everytime I am trying to "conect" my iPhone iTunes is not showing the iPhone and worst of all is that if you open the windows Task Manager there is a program getting the 99% of CPU and this program is Syncserver.exe if you "End Task" you receive a message telling you the sync with your iPhone is not possible because Syncserver is not "running".
May I do "something" to solve this problem?

You haven't done anything wrong here, but the CA products have been known in recent times to interact with iTunes. One of the symptoms that gets my CA radar rotating is the Syncserver.exe trouble that you're getting.
I'd first try the documentation that kalda01 links to in the following post. (You may need to log on to CA Support first in order to open those links.)
http://discussions.apple.com/message.jspa?messageID=10525876#10525876
If none of those seem relvant to your setup (I'm not sure if kalda was using 2010), I'd try getting in touch with CA support and asking them what they'd recommend by way of configuring your CA to stop interfering with iTunes. If they link you to a knowledge base article over there, would you mind linking us to it? (I don't have a lot of luck myself searching through CA's website to find relevant resources for the iTunes issues.)

"Firefox doesnot respond" is not the same as "crashed" When it does not respond the whole system hangs , qonsequently it is impossible to send a krasch report. The only wayto get the system working is to shut it down and restart it

During browsing for 3-6 pages F-fox hangs the system with a error message "Firefox doesnot respond" and dimming the screen.
Nothing else but switch of the computer and restart it.
After browsing for 3-6 pages it is the sam procedure.

The System.keychain Conundrum: THE REAL SOLUTION.

Symptom: After applying an update or some kind of instance where a shutdown occurred, upon rebooting, Mac OS X will demand a password for System.keychain. No password will ever work, not even root.
I had this happen to me and no one anywhere seemed to know how to fix it except for temporary workarounds that really didn't work.
First off, let me tell you what WON'T work as a solution:
1. Deleting offending AirPort network passwords in System.keychain - All you're doing is making OS X forget the passwords of those base stations in your Preferred Networks list (Network Preferences). If you attempt to put the passwords back and apply the changes, OS X will again demand the password for System.keychain.
2. Keychain First Aid - It will think that nothing is wrong with System.keychain, so as long as it is there.
3. Repair Permissions - Everyone believes that repairing permissions is the cure-all method for any problem with Mac OS X. It won't work because it already has the correct permissions (root:admin 755).
4. Deleting System.keychain itself - You won't ever get it back, and any base station added to your list of trusted networks will not have its password saved. Sure, it may save for YOUR login.keychain, but what if you have multiple users?
5. Replacing System.keychain with another from a known good system - This doesn't work either, and I'll explain why a little later.
6. Deleting /Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist - That has nothing to do with the problem.
7. Duplicating your login.keychain and renaming it as System.keychain - Sure, you'll be able to unlock it with your admin password, but that doesn't solve the problem.
No one - not even from Apple themselves (phone reps and store Genius
Bars) - knew how to fix this issue. Google or search the discussion boards all you want; you'll be wasting your time as no one really seems to know what the problem is and have employed one of those seven methods.
NOW FOR THE SOLUTION...
WARNING: This assumes that you are competent with the command line AND you have a working copy of OS X somewhere else nearby, preferably on an external disk partition. I'm not going to explain the basics of using the Terminal or how to access both of your systems at the same time. If you are afraid of screwing up, simply reinstall Mac OS X and say a few prayers that it will fix itself (assuming that another Software Update won't mess it up again).
The problem lies with a file deep in the bowels of OS X. It's /var/db/SystemKey. What it does is that it tells Mac OS X how to unlock the system keychain. It only knows the System.keychain specific to the computer, so if you import another System.keychain as a replacement, SystemKey won't know how to unlock it and you'll keep getting the annoying dialogs prompting for System.keychain's password.
So without further ado, this is how to stop the annoying dialogs once and for all:
1. AS THE ROOT USER, you will need to copy over /var/db/SystemKey from a known good system to your problematic system. Make sure that you preserve the permissions (0400). It is advisable that you are NOT booted from your problematic system.
2. If you have a good System.keychain, copy that over to /Library/Keychains on the problem system. If you accidentally deleted System.keychain, you can execute the following (again AS ROOT):
/usr/sbin/systemkeychain -C -f
This creates a new, working, empty System.keychain and effectively overwrites the old keychain.
3. Reboot to your system. You will be presented with different, more familiar (Change, Change All) dialogs. If you had any passwords saved in your list of preferred networks, just put them back in.
Best of luck.

A method that worked for me (and many others):
Delete the wireless router entry from the System keychain (do not just delete the password). The entry will automatically get re-created from the similar entry in the login (user) keychain. This solution was posted here within a few days of the release of 10.4.3.
