[Xen-users] Rouge domU's in xenstore

[Rus Foster <twattycake@xxxxxxxxx>]

We are trying to find out why we have some rouge entries in xenstore.
Example below (copied from xenstore-ls)

Any ideas. I've gone through a number of xenstore-rm -t
/local/domain/894 and no luck

Rebooting fixes the issue (on another server) but thats far from ideal
