- Plesk Onyx for Linux
Synchronization of all DNS zones via Amazon Route 53 extension fails with the following error in Plesk UI:
PLESK_ERROR: Error: Failed zone update example.com: Tried to create resource record set [name='subdomain.example.com.', type='CNAME'] but it already exists
CONFIG_TEXT: DEBUG [extension/route53] [5a7b322d01fec] Starting: /usr/local/psa/admin/plib/modules/route53/scripts/route53.php, stdin:
DEBUG [extension/route53] [5a7b322d01fec] Finished in 19.21434s, Error code: 255, stdout: Failed zone update example.com.: Tried to create resource record set [name='subdomain.example.com.', type='CNAME'] but it already exists
This is Amazon Route 53 extension bug with ID EXTPLESK-393. There is a limit on the number of records that can be retrieved in a single request (100), check Amazon documentation for details.
The bug is planned to be fixed in future updates of Amazon Route 53 extension.
As a workaround, manually delete the number of DNS records from Amazon Route 53 to make them less than 100 and sync again. All the records will be re-added.
