Kernel Panic Screen Reboots

    Just a couple days ago I was watching a video on Youtube, when all of a sudden I got a "Kernal Panic" error screen as seen here:


    I kind of shrugged the error off as a fluke, since most blogs and forums that talk about MacbookPro Kernel Panics are rarities. That usually don't occur again, and if they do often because of either minor issues, or on the otherhand major issues. So thinking it wouldn't happen again I used my Macbook for a while without a problem. Decided to launch Mozilla and start browsing the web (which seemed to work fine for 15 mins or so), when all of a sudden I got a second Kernel Panic error. This happened while a specific webpage was loading up (not Youtube). So that scared me, heck this is a fairly new MacbookPro. I used it again for a bit, and decided to try an experiement. I browsed for a while, then tried to visit the same webpage that gave me the Kernel Panic just before, & bam it happened again for a 3rd time!

    Ok so being a bit of a tech guru I decided to run these tests to make sure all is well with my machine:

    - Booted into Safe Mode
    - Ran Disk Utility under the Recovery Partition to verify the HDD Structure
    - Checked HDD Smart status
    - Ran TechToolPro v7 to do a thorough Disk Scan of every sector on the HDD
    as well as a Video Memory test, and Memory Test.
    - Booted into the Apple Hardware Test program to check my machine with the
    extended test selected
    - Verified and Repaired all Permissions errors
    - Scanned my HDD with my antivirus ESET CyberSecurity

    Every single one of the aforementioned checks I did came out fine. This all took hours to do... The only thing that is never okay so to speak is the permissions errors. Which have always listed a bunch of iTunes errors that show up, but never repair even when it says they did. But that's been that way for almost a year now. I believe there's another permissions error in there somewhere that's also always been there too though (which never repairs). Anyways the only thing I have noticed odd recently is our internet acting weird during the days this happened. Not just on my MacbookPro but on our iPhones too. We're all connected via WiFi, and have noticed some pages not loading, some videos pausing, server messages, 503 errors too I believe. I tried powering off our router and modem twice. But the Kernel Panics I mentioned earlier had still happened even after doing that.

    My next step is to call our ISP to make sure all is well on their end. Seeing as I haven't had a Kernel Panic occur while doing anything else, ONLY while browsing the internet. Which I have read on some blogs can happen do to bad network packets. If I'm correct then that might be what has happened. But why in the **** would a MacbookPro restart due to a Kernel Panic error just because of some bad Internet packets coming in? I would have thought pages wouldn't load, not some oblivion style error that reboots the machine! Think about it the Kernel Panics didn't happen during any of my tests which took hours to complete. The antivirus scan alone took 7 hours, on my 750GB HDD. I'm actually writing this post from the very same MacbookPro right now. The only
    things I have changed on my machine in the past two weeks was install a MAudio MBox Mini audio driver, iLoc License Key program, & install Pro Tools Express. All of which work hand in hand to make the external audio box work for recording vocals/music.

    The drivers and software are unsigned from what I recall... I had to disable the "Install Signed Applications Only" section of the Security panel in Mountain Lion before doing so. As far as I know they're the correct drivers for my Mountain Lion OS X 10.8.5. The other thing I installed a night or two before the issues started was the newest version of ESET antivirus which installs over the exsiting one. But they're good, I've done this many times and never had an issue. I think I did a Mozilla Firefox update once in the past two weeks too. But they're known for being really good on releases. I've also used my MacbookPro for two weeks since I first installed the external audio box (which connects via usb), and never had this happen. Btw these Kernel Panics happened while the external audio interface was disconnected. Again not something that happened before in two weeks since it's been disconnected many times. I'm positive my machine is fine something I can't really put my finger on made this happen, and I'm scared it will happen again while doing something important!

    1. I don't know what to do... Is there something else I can check?

    2. Should I still call my ISP to make sure all is well on their end?

    3. & why the **** would a Kernel Panic happen due to simple Network Packets (internet) not being received correctly over wifi that would cause a sudden reboot?

    Thank You

    I saved everyone of the Reports that came up after each of the 3 Kernel Panics happened. As per Apples little info about what the reports contain (bunch of garbled words and #'s), they mention to search it for a couple words that referr to serious hardware problems. I never found those words either while using notepad to scan them through. I'm wondering if it might even have something to do with the now FAMOUS HEARTBLEED BUG roaming the internet the past few days. Which I would think may have had ISP's doing weird things with their internet services.

    I would say the odds of it being a driver involved with one of these new installs is very high.

    Open Console app from /Applications/Utilities and look through the log at the exact time and date of the last KP and see if the log gives you any pointers.

    Look for a section in the log that says "last loaded kext". Kext files are similar to drivers and that last loaded kext in the log is very often the cause of the KP.

    The previous 2 Kernel Panics I had happen to have something similar to the above report. Which I will post below, hoping that it may help you diagnose my issue. They'll be in two small excerpts, both of which I'd like you to notice starting with "Panic" under the date. There probably is other information of use to you within the excerpt too.

    Thank you all very much for your time. Too bad I don't have Apple Care... Hope this issue can be resolved. I'm currently studying and my pockets can't take another hit right now. Like I said before I kind of kept away from using my laptop ever since I got the 3 Kernel Panics. Other then when I tested everything out as I mentioned in my first post that started this thread. But I have however began using my laptop since yesterday to post this, and browse a bit to see if the Kernel Panic would persist. I haven't had a Kernel Panic so far... One thing I did notice is the reports mention something about "Panic CPU," and "BSD process name: Eset" in all three reports. Not exactly in those words I just wrote (since each report differs). But it does lead me to think either I have a cpu issue, or the recent install of the new version of Eset I put on my machine this week has something to do with it? Again I'm no expert at reading these reports so I can't say for certain. And if it was some sort of bug in the new version of Eset antivirus, maybe the constant auto update feature of the program fixed/patched it. Which could be why I haven't experienced another Kernel Panic. Just throwing out some ideas...

    Are you running one of these iLok USB keys? That paceap.kext is a driver for the iLok system and that is my first guess at the issue, because the crash looks related to a file write operation.

    I would also remove eset. If you want to run an AV, take a look at the free ClamXAV.

    You should be able to find the kext files in this folder.

    There are so many reports of kernel panics, crashes, hangs, spins ect for the latest version If you want to keep using ESET CS revert back to version
