Submissions being duplicated with same uuid

Hi all, I’ve got a similar problem as well. As @dianedetoeuf mentioned ~2% (22 out of 1024) of my submitted forms have duplicated _uuids (11 duplicated uuids for 22 submissions). Their _ids are unique, and the submissions are not duplicated -they are genuine submissions.

I don’t know if it helps but here are the answers to the questions that @wroos asked:

  • UUID duplicates are both in table view and excel export.
  • Can’t reproduce it.
  • ID’s are different, but the uuid’s are duplicated.
  • Other than the username of the person, most of the data is different. (got 134 questions which some of them expected to be have same answers, not a duplication issue.)
  • When trying to view the submission, it works as expected, BUT when I try to edit I get an error:
    (this might be due to today’s server issue, will check again when the server is acting a little bit better.)
    (By the way, could there be a relation between this issue and the can’t edit issues recently?)

The data server for your form or the Enketo server is down. Please try again later or contact support@kobotoolbox.org. (500)

  • Forms don’t have any type of media attachment.

More information:

  • All the duplicated UUID’s occur within the relevant account. See screenshot for details:
    (In other words, there is no duplicated UUID between different accounts)
    (Censored usernames and Most of the UUID’s for security reasons.)
    UUID Replication-3

  • All of them are submitted via web.

One of the things I noticed is the submisson time. In @dianedetoeuf’s, @Bernard_26’s and my cases, the submission time of the duplicated UUID’s are so close to each other.

Will test more and update here.
Best,
