Comment # 7 on bug 1175642 from James Fehlig

I'm not sure why it is difficult for me to reproduce either of the crashes. For
the storage related one I have an NFS mount on the host which I then bind mount
to /var/lib/libvirt/images. libvirtd terminates after the timeout with no
crash. I'll need more details of your configuration.

Some other items that would be interesting to try if you are able:

Does the crash occur if you start libvirtd on the command line *with* the
timeout value? E.g. '/usr/sbin/libvirtd --timeout 60'. That would make it a bit
easier to use valgrind.

Can you see if the crash still appears using the latest libvirt release?
