I can't say why but I bet it has nothing to do with gluster. Try to look at
this issue as if there was no gluster involved.

I don't know what kind of application creates .xva files but does this
application really releases the files? How are you deleting them? What
user/application lsof says is hiding the files? Aren't you accessing the
files directly on the bricks somehow?
