"Create Snapshot Clone" in OEM fails against testmaster after OEM upgrade

Several snapshot databases were created using the earlier version of OEM, the issue started after the upgrade of OEM, for some reason OEM is trying to copy the tempfiles from the source test master database and it's failing with error.

We now think this is an OEM issue because it is trying to execute the snapshot clone differently on the host than it did on a previous OEM version.

I have 4 testmasters and can no longer complete a "Create Snapshot Clone" from OEM against any of them. We recently upgraded from OEM 13.3 to 13.4.4 per the admin (13.4 plus a patchset). I have alert logs from a failed clone AFTER the OEM upgrade, and an alert log from a previously successful clone against the SAME TESTMASTER before the upgrade. We had no issues with building these until recently and OEM is the only thing we believe has changed.

This is on an exadata x6 node and using sparse disk. Further detail to follow.
