MariaDB Error 1038: Out of Sort Memory
Description
This error indicates that MariaDB has run out of dedicated memory for sorting operations. It typically occurs when complex queries requiring large sorts (e.g., with ORDER BY, GROUP BY, DISTINCT) exceed the allocated sort_buffer_size.
Error Message
Out of sort memory, consider increasing server sort buffer size
Known Causes
4 known causesLarge Sort Operations
Queries involving extensive ORDER BY, GROUP BY, or DISTINCT clauses process data sets too large to fit within the allocated sort buffer.
Insufficient `sort_buffer_size`
The `sort_buffer_size` configuration parameter is set too low for the typical sorting requirements of your database workload.
High Concurrency
Multiple concurrent queries performing large sort operations simultaneously exhaust the system's available memory dedicated to sorting.
Inefficient Query Design
Poorly optimized queries may force MariaDB to perform unnecessary or oversized sort operations, consuming excessive memory.
