Via Net boot (10.7.5), running Casper imaging on a new computer, which is not in the Jamf database, once passed authorising the software to run you get "Casper Imaging quit unexpectedly" message. Ironically this doesn't stop the process from running as you can choose to ignore.
If the computer is in the Jamf database then Casper imaging works fine
Casper Imaging 8.52. works fine for both scenarios.
I am experiencing the same issue of Casper Imaging 8.61 unexpectedly quitting. This is with a clean install of 10.7.5. I discovered it as I was attempting to create a new NetBoot image. I haven't published the NBI on our Netboot server yet, so I don't know if it is still stable to use if you simply ignore the warning.
On 09-28-2012, I contacted JAMF Support and they created a defect ID.
What worked for me was making sure my NetBoot image was checked to run 'Diskless.' To confirm this, when in Casper Imaging, look at "Installation - /Volumes/Macintosh HD - disk0s2" This indicates the temp files are being written to the server and not to the local drive.
Thanks to Dan Kubley for this tip!
I'm currently on jss 8.62
I was also having this error until i recreated the netboot image again. 1) enable root account
2) change auto login with the root system administrator account
3) capture the netboot image with 10.8.2 server system image utility
4) resize the partition to 25GB.
The error went away. Give that a try.
