Hi all,

I'm currently trying to fix a machine that is kernel-panicking about once every other day. I've tried deciphering (based on the Apple developer's website) but still can't figure it out completely. It could be memory, but I'm not sure so I thought I'd toss this out and see if I might get some help from all you smart ones out there

Thank you in advance!!


Following is the panic log from the last 3 times:

Not a panic logger reader but I would say RAM. Do you have more than one stick in the machine so you can remove one and test the other, then swap?
