MariaDB Error 1614: XA Transaction Deadlock Detected
Description
This error indicates that a branch of an XA (distributed) transaction has been automatically rolled back due to a deadlock. A deadlock occurs when two or more transactions are waiting for each other to release resources, resulting in a standstill. In this context, the deadlock was detected within the distributed transaction system, leading to the rollback of the affected branch to resolve the contention.
Error Message
XA_RBDEADLOCK: Transaction branch was rolled back: deadlock was detected
Known Causes
3 known causesConcurrent Resource Contention
Multiple XA transaction branches concurrently attempt to acquire locks on the same database rows or tables, leading to a circular wait condition.
Inconsistent Lock Acquisition Order
Different distributed transactions acquire locks on resources in varying sequences, creating the classic deadlock scenario where each waits for the other.
Long-Running XA Transaction Branches
Individual branches of an XA transaction hold locks for an extended duration, increasing the window for other transactions to create a deadlock.
