MySQL Error 3001: Master Query Incomplete, Slave Aborted
Description
This error signifies that a SQL query started on the MySQL master server but did not complete successfully, causing the slave server to abort its replication process. It indicates a potential data inconsistency between the master and slave, as the slave did not fully apply an operation that partially executed on the master. This often occurs during replication failures or when the master encounters an issue mid-transaction.
Error Message
Query partially completed on the master (error on master: %d) and was aborted. There is a chance that your master is inconsistent at this point. If you are sure that your master is ok, run this query manually on the slave and then restart the slave with SET GLOBAL SQL_REPLICA_SKIP_COUNTER=1; START SLAVE;. Query:'%s'
Known Causes
4 known causesMaster Server Interruption
The MySQL master server experienced an unexpected shutdown or restart while a query was being executed, leading to its partial completion.
Master Query Failure
The specific query failed on the master due to issues like deadlocks, constraint violations, or other internal errors, preventing its full completion.
Master Resource Exhaustion
The master server ran out of critical resources (e.g., memory, disk space, CPU) during the execution of the query, leading to its incomplete state.
Corrupted Master Data
Corrupted data or indexes on the master server prevented the query from completing successfully or caused it to execute only partially.
