Sort aborted Error in MySQL Error Log

现象

[ERROR] lines containing "Sort aborted" are present in the MySQL error log file.

[Warning] Sort aborted : Out of memory (Needed 24 bytes)
[ERROR] Sort aborted

From MySQL 5.5.11 onward:

[ERROR] mysqld: Out of sort memory; consider increasing server sort buffer size
[ERROR] mysqld: Sort aborted: Query execution was interrupted

原因

There are many possible causes of Sort aborted errors, see details below.

解决方案

From MySQL 5.5.11 the error messages have been made more specific. The 5.5.11 errors have 5.5.11 at the start of the line in this description. In addition in 5.5.11 and later if you turn on --log_warnings = 2 the error messages will give details of the host the client connection is coming from, the user account and the query to assist in diagnosing the cause.

Insufficient disk space in tmpdir prevented tmpfile from being created

Make more space available.

Insufficient memory for sort_buffer_size to be allocated

Add more memory or adjust settings to use less memory.

5.5.11 error: [ERROR] mysqld: Out of sort memory; consider increasing server sort buffer size

Somebody ran KILL in the middle of a filesort

Normal, no action required.

[ERROR] mysqld: Sort aborted: Query execution was interrupted

The server was shut down while some queries were sorting

Normal, no action required.

[ERROR] /opt/mysql/product/mysql/sbin/mysqld: Sort aborted: Server shutdown in progress

A transaction got rolled back or aborted due to lock wait timeout or deadlock

Normal, no action required. The lock wait timeout or deadlock might be something you want to investigate if that is not expected, though it is normal for these to happen sometimes in transactional databases.

Unexpected errors, such as source table or even temporary table was corrupt

Look for possible causes.

Processing of a subquery failed which was also sorting

Possibly look for a cause for the subquery to fail or consider it normal, it could be either.

Wrong number of arguments for a function

Fix the function call.

5.5.11 error: [Warning] Sort aborted : Incorrect number of arguments for FUNCTION test.f1; expected 0, got 1
