Problems loading the DAS

If the DAS software has been deliberately killed during a session, it may not always reload correctly. If this `invalid queue identifier' message appears, just repeat the BE command. It should load by the fourth attempt. If not, something is wrong --- phone somebody. If loading is still a problem, check the power LED's in the DAS ADC rack and on the IVC rack; also reset the correlator micro (reset button is on the left of the correlator boards).
