We're running 4 DL2's. One fixture will at some point during a night loses output. The lamp is struck, you can still see it through the lense, but there is no image. Resets do not help. the only thing that solves it is turning off the fixture for a few minutes and powering it up again. Server problem? Running latest software version in fixtures and CMA. Hog Ipc, Hog 3 mode. This problem started a few months ago and seemed to go away with the previous software upgrade, but has reappeared recently and the newest software upgrade doesn't seem to help.
