Help Me Diagnose The Source of this Kernel Panic

[NickD]

So I've been having kernel panics frequently on the iMac in my sig and was wondering if you could help me figure out what the source is. Here's the info that OS X gave me:

panic(cpu 0 caller 0x0012EB24): lck_mtx_unlock_wakeup: mutex 3ec5d20 holder 47de3d0

Looks like a network I/O problem. Try disconnecting and see if it continues. You see the problem happens to be Content Barrier X. Looking at the name I'm going to guess you didn't install it. Damn filters

And I almost forgot to say you blog looks good

I would agree on this being a network problem as stated above.

Is there any simple way to take care of this permanently?

Are you using the most recent version? If not, I see no official fix. You could try to get around it, à la Tom Wood and myself (not ContentBarrier btw), but I don't condone that sort of activity.

Sorry I can't be of more assistance.

Kernel Panic While Computer Idles

I have recently tried leaving my computer open and idle while i sleep, the last three or four times I've left the laptop open and not asleep I've woken up to find that it has shut itself down due to an unexpected error.

Here is the system error message i get once i turn it back on.
I think it may be the weather channel screen saver i recently downloaded so ive deleted it. I'm just posting this so maybe someone who does know what it is will see it and be able if someone else can diagnose the problem or cause before i could.

Here is the error reading i get.
