Got error during FLUSH_LOGS

Production Risk

Medium — logging failure can disrupt replication and point-in-time recovery.

What this means

ER_ERROR_DURING_FLUSH_LOGS (1182, SQLSTATE HY000) occurs when MySQL fails to flush and rotate binary logs or error logs. This is commonly caused by disk full conditions or permissions issues on the log directory.

Why it happens
  1. 1Disk full when trying to create a new binary log file
  2. 2Insufficient permissions on the MySQL log directory
  3. 3File descriptor limit reached
How to reproduce
trigger — this will error
trigger — this will error
FLUSH LOGS;  -- fails if disk full or permission denied

expected output

ERROR 1182 (HY000): Got error during FLUSH_LOGS

Fix

Free disk space and retry

Free disk space and retry
-- Check disk usage, purge old binary logs
PURGE BINARY LOGS BEFORE DATE_SUB(NOW(), INTERVAL 7 DAY);
FLUSH LOGS;

Why this works

Removing old binary logs frees space, allowing new log files to be created.
