           Summary: sometimes vm.drop_caches = 3 deadlocks domU
           Product: Xen
           Version: 3.0.3
          Platform: x86-64
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Guest-OS
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: jamundso@xxxxxxxxx

Sometimes, in a CentOS 4 domain (CentOS release 4.6, 2.6.9-67.0.20.ELxenU) on a
CentOS 5.2 dom0 (2.6.18-92.1.6.el5xen), the domU just deadlocks - no messages,
nothing logged. The dom0 and other domU's (CentOS 5.2) are fine. I've been able
to sort of re-create it when there is a "normal" application and user load on
the system by running "echo 3 >/proc/sys/vm/drop_caches". I will try to
re-create it consistently in a test environment.
