More likely, you encountered the same symptoms as a previous bug
reported and fixed in 2011, but where the cause of those symptoms is a
different bug.  But without more details, such as what version of
libvirt you are using, what distro provided that build, and what action
you were attempting when things locked up, it's hard to say if it is a
known issue.

That bug was created against RHEL 5.  If you are going to report more
details via bugzilla, then you are better off opening a new bug that is
relevant to your setup (whether that be against RHEL or Fedora or
upstream libvirt itself) rather than trying to piggyback on an old bug.

In the past, when this has happened, it was because libvirt disobeyed
locking rules in its code; and a workaround was to restart libvirtd.
