None of these failed with error 193 but were sent to a mixture of operating systems.
In this example _0 failed immediately and _2 was sent.
_1 and _2 went into PVer.
All the above were Windows machines. After the resumption _3 went to a Linux machine and from memory also went to PVer.
_4 was sent to a Linux machine and on return _3 and _4 became valid.
Another oddity is that the points granted to the valid work units is not an average of their claimed points.
