           Summary: Guest domain gets unresponsive after running for some
                    time
           Product: Xen
           Version: unstable
          Platform: x86-64
        OS/Version: Linux-2.6
            Status: NEW
          Severity: blocker
          Priority: P1
         Component: Guest-OS
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: fsantaclara@xxxxxxxxxxxxxxx


Hi,
  We're running XEN 3.1 on a intel core 2 quad (Intel(R) Xeon(R) CPU          
E5345  @ 2.33GHz). 
OS: OpenSuse 10.3 
Kernel both host and guest: 2.6.22.5-31-xen.
Packages:  xen-3.1.0_15042-51
           kernel-xen-2.6.22.5-31  
           xen-libs-3.1.0_15042-51
           xen-tools-3.1.0_15042-51

  We have 3 guests running. At some point, apparently random, a guest will
become unresponsive. There's nothing on the logs that suggest any problem on
the host and guest before/after the crash.
  When the guest is in an unresponsive state, it's still running as far as the
host is concern. The xm top command shows the guest in question with 399% CPU
usage. We are also still able to get into its console but the virtual server is
completely frozen.

  Thanks,

Filipe Santa-Clara
