[libvirt] libvirt quietly dies (on keep-alive error handling?)

[Igor Lukyanov]

Hi all,
we detected a floating bug of 1.0.2 version.
Libvirtd mysteriously and quietly dies (without core dumps or entries in dmesg/syslog) with the following log messages.
If you have any ideas of what it might be and how to deal with it - please give a hint. Many thanks.

Here is the tail of libvirtd.log:
