MariaDB Error 1875: Slave SQL Thread Busy Stopping
Description
This error indicates that a 'STOP SLAVE' command was issued, but the Slave SQL thread is currently engaged in an ongoing task. The thread will not stop immediately but will complete its current operation before shutting down. This message typically signifies a delay rather than a critical failure in stopping the replication.
Error Message
STOP SLAVE command execution is incomplete: Slave SQL thread got the stop signal, thread is busy, SQL thread will stop once the current task is complete.
Known Causes
3 known causesActive Transaction or Query
The slave SQL thread is executing a long-running transaction, a complex query, or a DDL (Data Definition Language) statement that must finish before the thread can terminate.
Significant Replication Lag
The slave SQL thread is processing a large backlog of replication events, and the current event is part of this extensive catch-up process, delaying the stop operation.
Resource Bottleneck
Insufficient CPU, I/O, or memory on the slave server is causing the current SQL thread task to execute slowly, prolonging its completion.
