unable to scan filesytem

I've made a few images without any problems but recently the process has either crashed (on a Power PC iMac) or gets to the end but gives me an error in the log (intel iMac). The only thing different is that I've added some updates. Maybe something wrong with the order. The error I'm getting in the log is - Creating the deployment DMG and scanning for ASR Rename the deployment volume Volume on disk2s2 renamed to OS-Build-08-05-19 Build a new image from folder... 16:49:54 16:49:56 Scanning image for ASR Image to scan is ./ASR_Output/08-05-19.dmg [color=Dark Red]unable to scan filesystem - 79.
