We've come across an issue where when the filesystem is very full, and nginx tries to write to it, we get "task blocked for more than 120 seconds" messages from the kernel, nginx hangs and we can no longer access the fs.  When a file is uploaded via nginx, nginx writes to a .tmp directory on the disk before moving the file to its destination.  nginx can't be kill -9ed, it needs a reboot.

It would help to see df output for space and inodes of the XFS 
filesystem in question.
