You shouldn't have to restart bro for it to pull in updates from intel files.

It's suspicious that you say bro crashed at 7am and that cron job runs at 6:55.

It's possible that something went wrong during the restart and bro just ended up stopped.  I could see 'broctl restart' leaving the cluster in an inconsistent state if it gets interrupted.

I'd just remove that job (since intel files should auto update on their own) or try changing the time it runs at to 6:57, which should at least avoid it running at the same time as cron.
