Some of form results do not show up in database

Hi, I have a quite basic like this. Daily 200 visitors visit my app in average. 15 of them fill the form. But some of them do not show up in the database. It happens very rarely (I got this warning only for 4 times so far)

Do you have any idea? This is big bug for me because it is sale form.
