Error -89123 (PXI-6281)

[xl600]

When I try to self cal my analog cards, I receive an error -89123 (Hardware necessary for this route is in use by another route or routes).  I have no analog tasks running, but I do have some trigger signals routed, a digital output task running, and a digital input task running.

Can Self Cal be run in this condition?  If not, can anything be active on the card at all?

Thanks,

Seems like nothing at all can be active.  If I route any PFI, the mere existence of the route prevents self-test and self-calibrate from functioning.  That strikes me as though a card reset would be necessary prior to self cal.
