[BUG] Cron uses 100% cpu

[bonnee]

I'm running the collector image from a Raspberry Pi and cron does not work without specifying a custom schedule from docker-compose, just like #121. If I override the schedule, the collector works and I receive data on my main server. In any case, cron consumes 100% CPU all of the time.

I'm attaching collector log collector.log
