I've disabled the drones for the evening. I think I've determined a recently introduced memory leak or some form of resource exhaustion which is accelerated by the load caused by the drones. I've ruled out a bunch of other causes over the past 2 weeks and have one final avenue to pursue. Thanks for your patience as we nail this last bug and get the system to the level of stability that we had a couple of months ago.
The network is still available and ATC is, of course, hard at work
