Body: <p>We have been facing a recurring issue where Civi is duplicating contacts. We were able to test and confirm that it happens whenever a person logs in, and then another duplicate contact is created every hour from then on by some sort of cron that we have yet to identify.</p>
  <p>We are not entirely sure where it's coming from. We have tried turning off plugins we thought could be responsible with no success.

  <p>We are wondering if there is any cron inside of Civi that could be responsible for this, or perhaps it has something to do with our duplication rules?</p>
  <p>Wordpress version: 5.4.2

  <p>Any help would be appreciated. Thanks</p>

Title: Contacts Duplicated on Login for Wordpress
ThreadText: # Contacts Duplicated on Login for Wordpress
  
  (Asked by: username_0 on 2020-07-31)
  
  We have been facing a recurring issue where Civi is duplicating contacts. We were able to test and confirm that it happens whenever a person logs in, and then another duplicate contact is created every hour from then on by some sort of cron that we have yet to identify.
  
  We are not entirely sure where it's coming from. We have tried turning off plugins we thought could be responsible with no success. We have tried rebuilding the civicrm\_uf\_match table with no success. We do not believe it is coming from non-Civi related plugins such as Woocommerce or Gravity Forms or Give Donations. We see no evidence that it's role related either.
  
  The only thing we're sure about is that these duplications happen when someone logs in, and that a new duplicate is created every hour after that. The duplicates only contain Name and Email Address.
  
  We are wondering if there is any cron inside of Civi that could be responsible for this, or perhaps it has something to do with our duplication rules?
  
  Wordpress version: 5.4.2
  Civi version: 5.26.2
  
  Any help would be appreciated. Thanks
