In cron tasks, use absolute paths to executable files and scripts, since the cron environment is different from the user's.
Save stdout and stderr to log files to debug problems with tasks.
Cron uses the system time zone. This is critical when working with servers in different zones.
If a task can run longer than the start interval, use flock or similar mechanisms.
Check cron expressions in the generator before adding them to the server. One mistake can lead to thousands of launches.
Use monitoring services (Healthchecks.io, Cronitor) to track task completion.
In crontab, add comments describing each task for future administrators.
Don't run all tasks in `:00` minutes. Distribute the load over different minutes.
