Thanks. I'll see if I can get a scheduled maintenance check on this.
The disks seem to be good as they are a 0+1 RAID and all internal tests show them to be in good health along with the controller. Would memory be a good suspect?

If it was in a funny process state, I'd guess that there was some hardware problem that caused a disk write request to hang up. You can get stuck in uninterruptible disk wait for quite a long time if the disk doesn't respond.
