MySQL: Out of Sort Memory

The ERROR 1038 (HY001): Out of sort memory, consider increasing server sort buffer size error occurs when we’ve allocated insufficient memory to the database. When this occurs, you’ll need to allocate additional memory.

The exact amount depends on your needs, so we suggest you investigate system performance and determine if the resources are sufficient or not.

As of now, this error might not be caught and presented as a standard error. We’ll look for a fix which would let us present this error as a standard error popup.

Spotting the Error

Whenever this error would occur, you’ll be unable to investigate some system resource, such as Low Code records, pages, and users.

Docker Compose

When you’re running the database with Docker Compose, you’ll need to update the service configuration and include the --sort_buffer_size command. In the following example, we set the sort buffer to 1024KB.

version: '3.5'

services: server: // …

db:
  image: mysql:8-debian
  command: --sort_buffer_size=1024K
  networks: [ internal ]
  environment:
    // ...
  restart: on-failure
  // ...
