Xen users - Apr 2005 - lvm/xen too many files opened

I have hopefully a quick question for the Xen masters out there. I have 
a few xen domains running on moderate hardware (x86 p4 with HT). The 
unprivileged domains are running on a LVM snapshots of a template to 
save time in deploying test domains. While running nessus inside one of 
the domains, there seems to be an issue with too many files getting 
opened and my LVM snapshot (really a CowFS in this sense) becomes 
unusable and unrepairable so i cannot rebind to a new domain. Has 
anyone else run into this or know how to prevent this from happening? I 
understand you may point a finger at LVM, and if that is the case, i 
don''t mind you telling me that ;)

It''s LVM. The dm-snap driver could certainly do with some work. It
generally works OK unless a snapshot ever runs out of space, but I
wouldn''t totally trust it.

Does anyone know if its actively being developed? If not, we may have to
invest some effort...
