Summary: Command hang up when execute "service xendomains stop"
Product: Xen
Version: unstable
Platform: x86
OS/Version: Linux-2.6
Status: NEW
Severity: normal
Priority: P2
Component: Hypervisor
AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
ReportedBy: she11c0de@xxxxxxxxxxx
Process hang up when execute "service xendomains stop", after this command, i
also execute "brctl show" and "ifconfig -a", all of them hang up, those
command not response, CTRL+C not take affect too.
Use ps -ax , i had see those process STATE is D, here is output :
