[sheepdog-users] sheep 0.8.0 crashs during live disk migration

I am running sheepdog 0.8.0 and today morning I found the following entries
in my log:

After this sheep has terminated. 
















What I tried at this time is to migrate a disk from a qcow2 file into
sheepdog. This was a live migration of a running vm, via the qemu monitor
command drive_mirror (actually this is done by Proxmox the virtualization
solution we are using). As far as I understand 0.8.0 should support live
disk migration?
















At least it would be great to avoid the crash, to avoid the performance
impact of the recovery process. 
















Regards
















Gerald
