Hmm, so a schedule is returned by scheduleResourceOperation, which
suggests that the operation was scheduled, but no operation history ever
gets created... Did you check the Server log for errors? Can you tell if
the operation is getting executed in the corresponding Agent?

Ian,
Thanks for the suggestion. I tried removing the criteria (there is
really only resource id and job id) but neither worked. I went ahead
and commented out my waitForOpertion() call and proceeded to wait and
then try the getSnapshotReport() call and started having a problem,
which surprised me because that code was working before. I am now
wondering if that error might shed some light on why the
waitForOperation() call is failing.
The new failure is:

{snip]
Again, the sequence of events is:
- invoke operation to turn on diagnostics
- wait for operation to complete (commented out now)
- delay for 2 minutes
- invoke getSnapshotReport()
The first invoke and the wait seem to complete normally (I see the
operation being performed by the agent) then the traceback starts at
the getSnapshotReport() call.
I have attached the full traceback if it's useful.
Any ideas?
