I'm using three servers for Casper 9.73 imaging: The JSS is running under CentOS 6.5 on an IBM box, the distribution point is an Xserve 2009 running 10.9.5 and the NetBoot server is another Xserve 2009 running 10.9.5 for NetBoot across subnets with this command:
bless --netboot --booter tftp://10.120.202.21/NetBoot/NetBootSP0/CasperYosemite.nbi/i386/booter --kernel tftp://10.120.202.21/NetBoot/NetBootSP0/CasperYosemite.nbi/i386/mach.macosx --kernelcache tftp://10.120.202.21/NetBoot/NetBootSP0/CasperYosemite.nbi/i386/x86_64/kernelcache --options "rp=nfs:10.120.202.21:/private/tftpboot/NetBoot/NetBootSP0:CasperYosemite.nbi/NetBoot.dmg"
I seem to be able to image approximately 8 machines at once, unicast. More than that and some machines will get stuck. They are logged in as adobeinstaller, but they fall asleep before they can install anything and waking them up doesn't seem to help. The imaging process is stalled for some reason.
The only way around this is to reboot into Recovery mode, Open Terminal, resetpassword and reset the root (System Administrator) password, then restart. They'll stall while logged in as adobeinstaller again and then I can logout, login as root, re-issue the NetBoot command and reboot.
My working hypothesis is that this problem occurs because the NetBoot process is very slow once we have a large number of machines trying to boot unicast. Any suggestions? I could have opened a bug report but thought I would post this publicly to see if anyone else is experiencing the same problem.
My client machines are being imaged as 10.9.5 (block copy from an AutoDMG created image) along with Adobe Creative Cloud 2015 including only the modules we need.

@endor-moon have you tried making a test configuration that includes just your base OS and one package that gets installed at reboot to see if you have the same issue or not? Maybe the issue is being caused by one of your packages. Our workflow with JSS 9.72 and Casper Imaging 9.72 doesn't exhibit this behavior. You can see our workflow in the attached image.
Thanks, @mpermann. It is only doing this on 4 out of 15 machines or so, which makes it a low priority. Just wanted to ensure JAMF is aware as a change to their startup scripts may be warranted. I did start my imaging with very few items and built it up slowly. I'm guessing this is the result of slow boot times and sleep mode hitting the machine before the scripts are run but since waking them up doesn't help, there must be more to the problem than just that.
