I've been getting this issue for the past few months. Apple won't look at it regardless of my apple care being good for the next year, since I have the operating system on a third party SSD.
They suggested I purchase a new SSD as it might have been corrupted, and I did. I installed a clean opy of OSX El Capitan, yet the issues persist!
Here's the Panic Report:

Best Answer
On first glance, it appears that your memory is going (or has gone) bad.
The way to fully diagnose it, is to remove all but one "stick" of memory from your MBP. Rerun the memory diagnostic software and/or AHT and see if the error persists. Make a note of the address where it fails.
Then, remove that stick, and replace with another and repeat the test. Keep the failed memory sticks off to one side so you know which one failed.
If all fail in the same address, chances are it's your logic board. If only one fails at a particular address, it's that module. You'll have to replace it.
Update:
(Given that it passed on the first go round after removing one of the modules)
I did some quick research on your particular Macbook Pro and according to EveryMac.com, while you have an official limit of 8GB, you can actually install a max of 16GB.
Since you have the machine open now's a good opportunity to upgrade to the max because the prices are quite good. I have reccomended this particular memory kit to someone with your model Macbook just recently.
