MySQL Error: Sort aborted

Question

I have MySQL 5.1 on Windows 2008 which has 8G Memory. The error occured every two seconds on Event Viewer. The error is

D:\\SW\\MySQL\\MySQL server 5.1\\bin\\mysqld: Sor

Answer 1

There are at least a few known things to cause this message:

• Insufficient disk space in tmpdir prevented tmpfile from being created.
• Insufficient memory for sort_buffer_size to be allocated.
• Somebody ran KILL in the middle of a filesort.
• The server was shutdown while some queries were sorting.
• A transaction got rolled back or aborted due to lock wait timeout or deadlock.
• Unexpected errors, such as source table or even tmp table was corrupt.
• Processing of a subquery failed which was also sorting.

Check these, and I bet your issue will be resolved.

Answer 2

Please check that you have enough free disk space that MySQL can write to. 'Sort aborted' commonly occurs when there is no disk space left.
