Here is (the most detailed) answer/solution of Darren Dunham:
-------------------------------------------------------------
I've seen similar behavior on '/' when there is a RT process with files
open on that partition.  The only common RT process is xntpd.  Do you
have that running?  If so, shut it down and try again.

'ps -ecf | grep RT' will show those processes.  RT in the 4th column is
a real-time process.
