WIN2003下的MYSQL问题！

似虫非虫

虚拟主机服务器，MYSQL数据库总量约1GB左右。

版本是4.1.14，配置时选择：Dedicated MYSQLSERVER MACHINEMO与Multifunctonal Database模式，最大链接数为1400!

运行中经常出现读取数据缓慢，无法读取等现象。当时系统内存充足，无不良现象！

WINDOWS日志里显示：D:\mysql\bin\mysqld-nt: Forcing close of thread 141660  user: 'a08272046359'

'a08272046359'这里各个数据库名都出现了！

这是2003的兼容性问题还是我的MYSQL没配置好呢？

11. # mysql-data-dir/my.cnf to set server-specific options
    
12. # (@localstatedir@ for this installation) or to
    
13. # ~/.my.cnf to set user-specific options.
    
14. #
    
15. # On Windows you should keep this file in the installation directory
    
16. # of your server (e.g. C:\Program Files\MySQL\MySQL Server 4.1). To
    
17. # make sure the server reads the config file use the startup option
    
18. # "--defaults-file".
    
19. #
    
20. # To run run the server from the command line, execute this in a
    
21. # command line shell, e.g.
    
22. # mysqld --defaults-file="C:\Program Files\MySQL\MySQL Server 4.1\my.ini"
    
23. #
    
24. # To install the server as a Windows service manually, execute this in a
    
25. # command line shell, e.g.
    
26. # mysqld --install MySQL41 --defaults-file="C:\Program Files\MySQL\MySQL Server 4.1\my.ini"
    
27. #
    
28. # And then execute this in a command line shell to start the server, e.g.
