[Xen-users] Xen 3.2 @ Debian 5.0 / Debian 4.0 DomU crashes daily
Hello,
on my xen host, Debian 5.0 I have few domU''s running, most of them are
Lenny''s, a couple is running at Etch (Debian 4.0). All domU''s
are running stable except of one (Etch / Debian 4.0). This one crashes almost
daily and I wasn''t able figure out the reason why.
Inside the domU there is nothing installed except of base system and Zimbra ZCS
5.0 and its dependencies.
