running 5.9.1.6, all was humming along. Went on 2 week vacation.
Came home to log file full of disk full events on alert.
Using 250 G SSD for "buffer". Alerts set for max 12GB and New set for 90 GB. Normal usage, storage stays "green" with those limits. Storage showed 30 KB available, "red".
Rebooted system and storage was back to all green. 24 hours and so far, so good.

Lost 3 days of alerts/storage although I can see the jpgs.

So you are saying that having a holiday will break BI5
