Mid-2011iMac, 3.1Ghz i5, 4 Gb ram has recently started "hanging" during operation. I'm typically running FMP 12, Safari with multiple open tabs, mail, calendar and message. I will randomly get the "beach ball", more frequently as the day goes on. Activity Monitor show nothing unusual, but system.log is filled with "memorystatus_thread: idle exiting pid #### [SleepServiceD]" messages. Trying to copy a section of log and get it onto my iPad so I can post it. Not running MacKeeper, or any other such utilities.


Mac Pro, Mac OS X (10.6.8), Server

    If you have not done so already, back up your data because what you describe may indicate an impending hard disk failure.

     

    Confirm you are running the OS X version in your profile (10.6.8). This was posted in the Mountain Lion forum.

     

    1. Run Apple Hardware Test by booting from your original grey Applications DVD while holding the d key. Any result other than "No trouble found" indicates a hardware failure that must be addressed first. Then,
    2. Boot from your original grey System Install DVD and choose Disk Utility from the Utilities menu. Select your startup volume (usually named "Macintosh HD") and from the First Aid tab, click the Repair Disk button. Reply with the results of any errors it reports in red.

    The OS X version in my profile is out of date. The machine came with 10.8 installed, and is now at 10.8.4. Have already run AHT, both simple and advanced, with no errors appearing. Same with Repair Disk.

     

    The machine is connected to a 10.6.8 server, with a Portable Home Directory. The contents of all the users' home directories are backed up nightly using MozyPro. There is an additional on-premises Time Machine drive that all users back up to. I was hoping to attach a portion of the system log, but can't find where TextEdit hid it on iCloud. I'll try again tomorrow when back at the office.

    In that case the Internet version of Apple Hardware Test can be invoked on your iMac by holding option d at startup, and you can boot OS X Recovery to run Disk Utility. No discs are required.

     

    The relevant system.log excerpts would be helpful.

     

    Mozy could be responsible for the periodic unresponsiveness. I know of no subscription-based offsite backup services that function well on a Mac.

    John, as I said above, have already run AHT and Disk Repair, with no errors. MozyPro is running on the server (10.6.8) and the problem is on my workstation (10.8.4). Now that I'm back at work, here's a small snippet from system.log.

    Perhaps you can tell something from this.

    The logs show the periodic "hangs" you describe but the underlying cause is not evident. To help determine that I suggest the following, in no particular order of importance:

     

    • Safe Mode or "Safe Boot" is a troubleshooting mode that bypasses all third party system extensions and loads only required system components. Read about it: Starting up in Safe Mode
      • Note that a Mac does not behave normally in Safe Mode. Screen redraws won't be as smooth, certain network functions are disabled, and some programs (iTunes for example) will not work at all. Read the above link for a more thorough description. Restarting your Mac normally will restore its previous environment.
      • If the periodic "hangs" do not occur in Safe Mode, it's a clue that will advance troubleshooting. The cause must still be determined though.
    • Creating a temporary account to isolate user-specific problems: Isolating an issue by using another user account
      • Log our of your normal account, log in to the temporary one, and determine if there is any change.
      • Delete the temporary account when you are finished testing.
    • Memory limitations: Using Activity Monitor to read System Memory and determine how much RAM is being used
      • Installing more memory is beneficial but is not a panacea for resource-hogging or poorly written programs.
    • Consider posting the results of EtreCheck in accordance with the following.
      • EtreCheck will collect and present a summary of certain system information that may reveal a potential cause.

    John Galt Level 8 Level 8 (36,310 points)

    Safe Mode should be instructive.

     

    Google Desktop may be causing the random hangs; I suspect it only because Google has yet to demonstrate the ability to write anything for OS X that is not a resource hog.

     

    In addition,


    • Mozy is in fact installed
    • Make sure Wireshark is the 64 bit version
    • Western Digital SmartWare does nothing beneficial and has been known to cause problems.

     

    There are several other processes launched at startup with which I am not familiar (FernLightning, "themha"???). Not all of them may be compatible with Mountain Lion, so if the periodic unresponsiveness does not occur in Safe Mode, your task is to search their respective developers' websites for updates, or methodically uninstall them.
