Illegal Activity (in WF trace)

So I get my workflow started with a do-start-workflow out of IDM (3.5.1,
UA with patch L).

Comes in, follows basically a parallel approver. Branches to the two
approvers, then if either deny, it goes to a Log Activity. If either
approves it goes to a Log activity.

Output of both Log activities hits the Merge activity.

I let the WF's escalate, then timeout, timeout defaults as a Deny. When
it hits the Deny log (Activity8), I see this error message in server.log
trace, Illegal Activity.

Is there a reference to what all these error messages mean inside UA? I
cannot find anything on Google nor Novell's site.
