[ovirt-users] ovirt-engine/api/imagetransfers - Indefinitely locked snapshot image if transfer does not start within 2 minutes

I've noticed an issue but I've not found any bugs related to this so it's not clear if it's a bug and just not been reported or if I'm missing something. It seems if using the ovirt-engine/api/imagetransfers call with a POST request such as say <image_transfer><snapshot id="b16290c4-6eef-469f-962d-31e9b76638e9"/><direction>download</direction></image_transfer> is done and more then two minutes pass (where the the ovirt-imageio-proxy/ovirt-imageio-daemon deletes the ticket), you can no longer download the snapshot image. I think this part is normal, HOWEVER the snapshot image remains locked indefinitely in this case. If the image starts transferring/downloading within the 2 minutes where the ovirt-imageio-proxy/ovirt-imageio-daemon ticket is valid, all is well and at the end of the transfer the snapshot image is automatically unlocked. oVirt 4.2.8.7-0.1.el7ev Anyone seen this before? What am I missing? - Justin
