FreeNAS grinding to a halt

[Grantp]

Hi, I've been using my FreeNAS with no problems for a while now, but recently it is running very slow, in fact it is grinding to a halt. When I try and copy from my Windows 7 PC to FreeNAS (CIFS Shares) it sets off at over 100 MB/second copies about 30 GB then basically stops. I have inclded some screenshots that appear to show I am running out of memory, is this the case and any idea of why after months of no problems.



As you can see as memory reaches almost 32GB usage the Network IO drops off to almost nil. I am still a noob when it comes to troubleshooting FreeNAS so any help would be appreciated.

I have included my raid config and my system info is in my signature.

Many thanks Grant

As gpsguy said, this sounds like a failing drive.
