[安装问题]我的mysql不能关闭

mysql版本:mysql5.0.41
操作系统:redhat as4 x86 u3
可以正常启动:
#./mysql.server start
但是不能关闭:
./mysql.server stop
Shutting down MySQL..............................................................................................[失败]
但是在mysql的log里面却没有错误信息:
071130 13:22:20 mysqld started
071130 13:22:20 [Note] /usr/local/mysql/libexec/mysqld: ready for connections.
Version: '5.0.41-log' socket: '/usr/local/mysql/var/mysql.sock' port: 3306 Source distribution
071130 13:30:24 [Note] /usr/local/mysql/libexec/mysqld: Normal shutdown

请教!……

Taxonomy upgrade extras:

PS有MYSQLD的进程,而且用下面的方式也不行
/usr/local/mysql/bin/mysqladmin --sock=/usr/local/mysql/var/mysql.sock --user=root shutdown -p

freebsd下我也遇到一回关闭不了mysql
最后只有重启服务器才解决了

有的……,我换了以下方式也无法关闭
/usr/local/mysql/bin/mysqladmin --sock=/usr/local/mysql/var/mysql.sock --user=root shutdown -p
