I've always gotten space cache generation warnings, but some time
after 3.0 they started going nuts.  I get:

space cache generation (14667727114112179905) does not match inode (154185)

and other similar messages (with a huge number and a smaller number)
at rates higher than one message per ms.  They don't happen
constantly, but they come in bursts big enough to fill my log buffer.
