xen.xend.XendProtocol.XendError: Invalid memory / mem_kb: None

[Chris Bainbridge]

I have a domain which is rebooting. When I do xm list I sometimes get
the following error; it's probably a race condition when the domain
restarts in the middle of being queried by xm.

xen # xm list
Unexpected error: xen.xend.XendProtocol.XendError

I saw that condition and reported a bug on 9/28 
(http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=264); however, I 
had not seen it since and closed the bug. Maybe we ought to reopen it?
