I see this on this one host in this specific instance, and I might resolve this by canceling the task an re-issue it, but if this is a bug I would like to describe it and get as much information I can gather.

I have a deploy task scheduled on a given host, and I was able to provision it in the past, however now despite having an active-imaging-task entry:

active_task_id: 80
computer_id: 8
task_status: 0
task_queue_position: 0
task_elapsed: NULL
task_remaining: NULL
task_completed: NULL
task_rate: NULL
task_partition: NULL
task_arguments: computer_name=pm04 computer_id=8 image_name=win_2012r2_mssql_alexbell profile_id=20 server_ip=clonedeploy.my-domain.local multicast=false pre_scripts="" post_scripts="" file_copy=False sysprep_tags="" task_completed_action="Reboot" dp_id=1 image_direction=push osx_target_volume="" munki_repo_url="" change_computer_name=true fix_bootloader=true partition_method=dynamic
task_type: unicast
multicast_id: 0
user_id: 6

and the proper files under /tftpboot/proxy/

/tftpboot/proxy/efi64/pxelinux.cfg/01-f4-4d-30-63-f5-e8.ipxe
/tftpboot/proxy/efi64/pxelinux.cfg/01-f4-4d-30-63-f5-e8.cfg
/tftpboot/proxy/efi64/pxelinux.cfg/01-f4-4d-30-63-f5-e8
/tftpboot/proxy/bios/pxelinux.cfg/01-f4-4d-30-63-f5-e8.ipxe
/tftpboot/proxy/bios/pxelinux.cfg/01-f4-4d-30-63-f5-e8
/tftpboot/proxy/efi32/pxelinux.cfg/01-f4-4d-30-63-f5-e8.ipxe
/tftpboot/proxy/efi32/pxelinux.cfg/01-f4-4d-30-63-f5-e8

And the files seems normal to me.

It doesn't start the imaging task but instead go to the imaging boot menu.

Just before that I see this screen flashing (attached file)

Any idea what else should I look at?
