Comment 2 Suqin Huang 2011-04-12 10:43:56 UTC 
guest quit with "Guest moved used index from 22685 to 23942" error once when I want to reproduce this issue
Comment 5 RHEL Program Management 2012-07-10 05:58:19 UTC 
This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.
Comment 6 RHEL Program Management 2012-07-11 01:59:54 UTC 
This request was erroneously removed from consideration in Red Hat Enterprise Linux 6.4, which is currently under development.  This request will be evaluated for inclusion in Red Hat Enterprise Linux 6.4.
Comment 9 Kevin Wolf 2013-04-04 12:52:47 UTC 
Happened only once and wasn't reported a second time since then. Doesn't look
like we have enough data to track it down.
