I created a crono job to send birthday email every day at 7:30 PM. It was supposed to run only once in one day!
Crono.perform(BirthdayJob).every 1.day, at: '07:30'Crono started at 7:30 as expected, but after that it "LOST CONTROLL", it was performed periodically, here is the log:

I encountered the same problem with rake task, could you find any workaround? @shenhf
@shenhf commented on GitHub (Nov 30, 2017):
@gastongouron Try to truncate crono_jobs table before start crono.
You can use 'database_cleaner' gem.
And in cronotab.rb, add :
DatabaseCleaner.strategy = :truncation, {:only => %w[crono_jobs]}
DatabaseCleaner.clean
PS. This is not working solution . This gem has serious problem. After days of running, It turned to be uncontrollerable!!
