           Summary: xen hangs until xend restart
           Product: Xen
           Version: 3.0.1
          Platform: x86
        OS/Version: Linux-2.6
            Status: NEW

          Priority: P2
         Component: Guest-OS
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: costexx@xxxxxxxxx


I have 5 instalations centos (5.0, 5.2) + xen (3.0.0, 3.0.1) fully updated and
in all i have a same problem. xen domains stop respondig after some time (3
months, 1 month or 1 week (seems to be random)). I can login in xen host, but
no xen console on domains, or ssh). In logs there is no entry since the domains
stop responding. If i issue a xend restart everything starts working as nothing
has happend. I can't remember in what state show xm list the machines are.
xm info from one of my systems:
