Non-recurrent agent worked 5 times in the night, in what could be the reason?

Hello, actually there is non-periodic agent which runs once a day, but for some reason, tonight it 5 times worked and sent the mail, what could be the reason? Agents for the crown, there were problems with the server time, the day before the server was reconfigured, ruled time, could this be the reason?

The mailing is the date of last shipment. In your case it lags behind the server time for 5 days. Bitrix compensated for the difference.
what you have described, running the periodic agent - Marcelino commented on July 9th 19 at 13:38
