I wish you a nice day! We hit a bug or something. Within Cacti, the maintenance time of the statistics of the data sources is set to 11:50pm, and at this time the maintenance issues an error. Until now, it was set to midnight, so we changed it, but it didn't solve the problem.
Thanks for your supporting.
