MySQL error 1079 (ER_SHUTDOWN_COMPLETE) indicates that the server process has finished shutting down, so any new or existing client connections are refused.
MySQL Error 1079: ER_SHUTDOWN_COMPLETE means the server has finished shutting down and cannot process queries. Restart the MySQL service or reconnect to a replica to restore availability.
%s: Shutdown complete
Error 1079 is thrown when a client tries to connect or send a statement while the MySQL daemon is in the final stage of shutdown or has already stopped.
The message "%s: Shutdown complete" is generated by the server thread and confirms that the shutdown sequence ended cleanly.
Clients that remain connected receive this error instead of a generic connection reset.
The server accepts a SHUTDOWN command, operating-system signal, or systemd service stop. During the grace period, incoming requests are rejected with error 1079.
Unexpected crashes can also surface this code if the recovery process calls the same shutdown handler before exiting.
Start by verifying that mysqld is no longer running.
If it is down, restart it with your service manager. If it is still stopping, wait until the PID disappears, then reconnect.
For HA deployments, redirect traffic to a running replica or read-only node while the primary restarts.
Manual maintenance: DBAs may issue FLUSH TABLES WITH READ LOCK followed by SHUTDOWN. Plan application downtime or automatic failover to eliminate errors.
Container orchestration: Kubernetes liveness probes can keep retrying during pod deletion, triggering 1079.
Adjust readiness/liveness grace periods.
Implement connection-pool back-off logic that retries with exponential delay when encountering HY000/1079.
Use Galaxy's AI copilot to embed shutdown-aware retry wrappers in stored procedures and application code.
Error 2006 (MySQL server has gone away) occurs when the server stops unexpectedly. Error 1053 (Server shutdown in progress) appears earlier in the shutdown cycle. Both are resolved by reconnecting or failing over, similar to 1079.
.
On modern SSD storage, small databases stop in seconds. Large instances with heavy write activity may take several minutes while flushing dirty pages and binlogs.
No. A clean shutdown flushes all changes to disk first. Ensure innodb_fast_shutdown is set to 1 or 0 for full consistency.
Your application may still point at the old TCP connection. Close stale sockets or restart the client to force a fresh handshake.
Yes. Galaxy's connection health checks surface shutdown states and prompt users to reconnect, reducing downtime frustration.
