Why? Don't do that.

No standard corrective action, because "dodgey" is far too unspecific.

It would be more appropriate to find out what happened, and make sure it
doesn't occur in the future. Therefore, no smoketest needed.

I do not think a smoketest is necessary or desirable.

If you can find any problems, then lets fix them, so we don't *need* to
test for them.
