MariaDB Error 1806: Slave Retry Transaction
Description
Error 1806 indicates that a MariaDB replication slave encountered a transient issue while applying a transaction from the master, requiring it to silently re-attempt the operation. This error is typically an internal mechanism for handling temporary inconsistencies or conflicts, but repeated occurrences can point to deeper replication problems.
Error Message
Slave must silently retry current transaction
Known Causes
4 known causesTransient Network Issues
Brief, temporary network disruptions or high latency between the master and slave can lead to replication inconsistencies, prompting the slave to retry transactions.
Slave Resource Contention
High CPU, memory, or I/O load on the slave server can temporarily prevent it from applying transactions promptly, leading to necessary retries.
Internal Database Contention
Occasional internal deadlocks or high contention within the slave's database during transaction application can cause the slave to back off and retry the operation.
Temporary Data Inconsistency
While rare, temporary data inconsistencies or unexpected states on the slave that prevent immediate transaction application can trigger a silent retry.
