[2013-12-05 09:32:24.651]: Error: API Call failed with message: Another task is already in progress.

We have seen this in ESXi 4.1 when the VM hardware version on the source was upgraded from 4 to 7. vRanger atempted to replicate this change, but when you look at the vCenter console at this replica, there is an informational message that needs to be cleared.

This same behavior was not present in ESXi5.x, the hardware upgrade was seemless.
