Kernel panic during screensaver - OS X 10.7.5
Hello everybody,
my Mac suddenly crashed, a few hours ago, due to a kernel panic ("You need to restart your computer..."). I'm on OS X 10.7.5 . This is my second kernel panic. The other one happened very long time ago. Please notice that my MacBook Pro suddenly freezes - sometimes, and for some time - during the screensaver.
I've submitted the following report to Apple, should I be scared? Is something failing on my MBP? I think not: the line "BSD process name corresponding to current thread: uTorrent" indicates that uTorrent crashed the Mac. Am I right?
Maybe it crashed because of bad interactions with Little Snitch? There is another line indicating that Little Snitch had caused some issues with it: "
Kernel Extensions in backtrace:
at.obdev.nke.LittleSnitch(2.4.4)"
Any help is appreciated. Thanks in advance!
