Server shutdown in progress

Production Risk

High — in-flight transactions are rolled back.

What this means

ER_SERVER_SHUTDOWN (1053, SQLSTATE 08S01) is raised when a query is sent to a MySQL server that is in the process of shutting down. Open transactions are rolled back.

Why it happens
  1. 1mysqladmin shutdown or SHUTDOWN statement was executed
  2. 2OS signal (SIGTERM/SIGKILL) sent to the MySQL process
  3. 3System reboot or container stop during active connections
How to reproduce
trigger — this will error
trigger — this will error
-- Occurs when server receives shutdown signal during active queries

expected output

ERROR 1053 (08S01): Server shutdown in progress

Fix

Implement connection retry logic in the application

WHEN Application should survive planned maintenance windows.

Implement connection retry logic in the application
-- Application-level: catch 1053 and retry after brief delay
-- Use connection pool with reconnect enabled

Why this works

Applications that retry on 1053 can reconnect once the server restarts, making the shutdown transparent.

What not to do

✕ Send SIGKILL to the MySQL process instead of a graceful shutdown

SIGKILL does not allow InnoDB to flush its buffer pool; recovery on restart is slower and risks corruption in edge cases.
