This type of linking is provided by KIX4OTRS AFAIR. This is NOT an OTRS issue.

Re-install the package.

DELETE FROM `database`.`link_relation` WHERE
`link_relation`.`source_object_id` = x;

This is/was a issue with misconfigured Mailserver AFAIR. Something with
Buffer Size or so. You may google it - or update (correct) your MX.
