instadmg completes in 5 seconds

Hi guys. Got an issue building 10.7.vanilla on one of my lion servers. This is what i get when I run instadmg. [code]Finding and validating the sources for 10.7_vanilla OS X Lion Update 10.7.3 - found based on checksum and verified in 5 seconds AirPort Utility 6.0 - found based on checksum and verified in less than one second iTunes 10.6 - found based on checksum and verified in less than one second Java For Mac OS X 10.7 - found based on checksum and verified in less than one second Safari 5.1.4 - found based on checksum and verified in less than one second Finding the Installer disc for 10.7_vanilla Found Installer Disc: /Users/admin/instadmg/InstallerFiles/BaseOS/InstallESD.dmg Setting up for 10.7_vanilla Cleaning InstaDMG folders Setting up InstaDMG folders Done[/code] So whats happening is that instadmg is running and says its done in 5 seconds but doesnt create an image. Any ideas whats going on? Some more details: running: lion svr 10.7.3, latest updates instadmg revision 444 restarted the lion svr and it still does the same thing source InstallESD is lion build 11A511 i have another identical lion svr and it builds images fine
