MariaDB Error 1440: Duplicate XID in XA Transaction
Description
This error indicates that an attempt was made to start or register an XA (eXtended Architecture) distributed transaction with an XID (Global Transaction ID) that is already in use. It signifies a conflict where the provided XID is not unique within the context of the transaction coordinator, often due to an existing active or prepared transaction.
Error Message
XAER_DUPID: The XID already exists
Known Causes
3 known causesXID Reuse
An application attempted to start a new XA transaction using an XID that was previously used and not properly released or forgotten by the resource manager.
Lingering Prepared Transaction
A previous XA transaction with the same XID was left in a 'prepared' state and was not fully committed, rolled back, or cleared from the system, making its XID unavailable.
Application XID Generation Error
The application's logic for generating XIDs is flawed, leading to the creation of non-unique identifiers for distributed transactions.
