>Description:
	The problem is that all processes try to write over the file
	system limit lock up.  This limit is software (user-level)
	limit.  After that, any processes accessing the same file
	system area (directory) lock up.  After 8 hours, entire file
	system became untouchable.  I'm using regular file system
	without softdep option.  This problem occured after Sep 22
	or little earlier in the curret-kernel.  I remember it was Ok
	before, but I don't remember when it was Ok.
>How-To-Repeat:
	just write data over the file system limit.
>Fix:
	Don't know.
