Unexpected eof found when reading file '/home/tmp/MYvFQFtT' (Errcode: 0)

执行sql语句时,出现如下错误信息:
Unexpected eof found when reading file '/home/tmp/MYvFQFtT' (Errcode: 0)
查看mysql日志
cat /var/log/mysqld.log | grep 100916
发现:
错误信息为: [ERROR] /usr/libexec/mysqld: Sort aborted
解决办法：
cat /etc/my.cnf | grep sort_buffer_size
vi /etc/my.cnf
将sort_buffer_size 改的小一些 问题就解决了
