MySQL cannot complete an internal CHECKPOINT operation because of an unexpected I/O or file-system problem, halting writes until the issue is resolved.
MySQL Error 1183: ER_ERROR_DURING_CHECKPOINT means the server hit an I/O or disk problem while writing cached data to disk during a CHECKPOINT. Free space, fix file permissions, then restart MySQL to clear the error.
Got error %d during CHECKPOINT
MySQL raises error 1183 when it encounters a low-level failure while executing a CHECKPOINT, the process that flushes dirty pages and key-cache changes to persistent storage.
The server pauses further writes to protect data integrity.
Applications may see stalled transactions or aborted statements until the underlying problem is fixed.
Disk-full conditions, damaged files, permission changes, or hardware I/O faults commonly break the CHECKPOINT sequence.
Large burst traffic can exhaust the key cache or InnoDB redo log, exposing latent disk-throughput limits and triggering the error.
First open the MySQL error log to capture the exact sub-error number reported inside the %d placeholder.
That number usually maps to an operating-system errno value.
Free disk space, restore lost permissions, or replace failing drives. After remediation, run FLUSH TABLES or restart MySQL to allow a fresh CHECKPOINT.
On cloud servers, sudden storage resizing can leave the data path read-only. Remounting the volume with write access clears the error.
On physical hosts, failing SSDs often surface errno 5 (I/O error).
Immediate hardware replacement and a full backup restore are required.
Maintain at least 20 percent free disk, monitor the InnoDB redo log growth, and schedule proactive OPTIMIZE TABLE operations to keep index files compact.
Place the MySQL datadir on fault-tolerant storage with SMART monitoring.
Configure innodb_flush_method=O_DIRECT to reduce OS cache pressure.
Error 1030 (HY000) needs similar disk checks but originates from a different storage-engine layer.
Error 1023 (HY000) indicates a write failure during table repair; many mitigation steps overlap with Error 1183 handling.
.
A restart clears the immediate lock but the root disk or permission problem must be addressed to prevent recurrence.
No. Writes may be silently stalled and data at risk. Investigate immediately.
Both InnoDB and MyISAM can trigger error 1183 because the checkpoint routine spans key caches and redo logs.
