Just for info:
With 3500 particular aircraft resulting in 6500 to 7500 flight movements per day, I noticed, that the ANRB software destabilizes, if it is run for more than a week without any restart of the software. Therefore I set up an automatic protocoll that closes ANRB software, then doing a back-up of MyLog.db and then stating ANRB again. The protocoll is launched each night during times of very low airtraffic and needs about 6 minutes to complete.
