I'm working with another engineer on this. He's a little unfamiliar with this area but I'll try to get him to signup on the list and respond directly. The script dumps a fair amount of info after a failure and so far there is nothing that is suspect in that data, i.e. it seems that there are no active mounts our anything else open. He will be putting a few more tests & basic debug print statements into the script - including between the unmount and the deactivate. Obviously this will change some timing. Also, I've asked him to re-try the deactivate in the script after the first failure. As we have more info, we'll post it.
