[Gluster-devel] Too many open files

[Brent A Nelson]

That's correct.  I had commented out unify when narrowing down the mtime 
bug (which turned out to be writebehind) and then decided I had no reason 
to put it back in for this two-brick filesystem.  It was mounted without 
unify when this issue occurred.

Thanks,

Brent
