My postgres db ran out of space. I have 27028 files in the pg_xlog directory. I'm unclear what happened this has been running flawless for years. I do have archiving turned on and run an archive command every 10 minutes.
I'm not sure how to go about cleaning this up, I got the DB back up, but I've only got 6gb free on this drive and it's going to blow up, if I can't relieve some of the stress from this directory over 220gb.
