I have been trying to unpick a mystery now for a week without success! I wonder if anyone can help.

We have two contacts (out of a database of c 7,500) where we're seeing some odd behaviour.

As an example - let's call him John Doe.

John Doe has a contact record, linked to a Wordpress user account. He has registered for an event recently (may or may not be relevant). His record has a linked current employer, job title, and address.

Every day at 12:13pm or 12:14pm, a duplicate John Doe account appears in CiviCRM, according to the change log created by John Doe, with matching:

  • Name
  • Email

But without

  • Linked Wordpress account
  • Job Title
  • Current Employer

I am at a loss to explain why. Things I have tried:

  • Disabling the Capitalisation Correction Extension
  • Disabling CiviRules
  • Examining the scheduled jobs log

Cron runs every five minutes. The Scheduled Jobs log shows that between 12:10 and 12:15pm each day, there are no scheduled jobs running:

2020-02-20 12:10:02 Finishing scheduled jobs execution.

2020-02-20 12:15:05 Starting scheduled jobs execution

There are no scheduled jobs which uniquely run at 12:10pm.

For each contact, there is only one item in the change log:

Change Log

I'd be extremely grateful for any advice on investigating this further as I am now drawing a blank (and I have 36 John Does in the database!)

We are currently on 5.13.4 (security upgrade imminent)

  • One thing they have in common that I've just noticed - the day before this started happening, their accounts were merged with a duplicate. In both cases, the newly merged contact then inherited a membership from their employer. Feb 20, 2020 at 20:04
  • Just to clarify - it may not be relevant - is it 12 am or pm? You've mentioned both, and it seems super-extra weird if it's pm.

  • @Demerit It is unfortunately the super-extra-weird pm! Feb 20, 2020 at 20:24
  • Does the new contact created have full name or only email? Any inbound activity? What is your unsupervised dedupe rule? Feb 21, 2020 at 0:58
  • Do you have detailed logging enabled? That might provide a few more clues.

This was resolved by removing the user's current employer, saving the record, and then re-adding the current employer. Seems potentially to have been some problem around the cascading membership?

  • Actually nothing to do with memberships - I have just created a fresh CiviCRM & WP install with 5 contacts, completely separate to the site above and with no memberships, and one of the contacts is cloning in almost exactly the way they did on the other site - this time 2 contacts (min) every evening 🤷‍♂️ Oct 25, 2021 at 9:10
