**My Application is used MySQL as a database.
and on my server MySQL is running.
server is highly configured on Win XP Os and other on Win 7.
Mysql version - 4.0.18-nt

My problem is , Mysql is stopped working everday after 5 to 6 hours.

It is like this (Microsoft Error Box):

mysql.exe has encountered a problem and need to close.
We are sorry for the inconvenience.

and sometimes

mysqld.exe has encountered a problem and need to close.
We are sorry for the inconvenience.

and sometimes

mysqld-nt.exe has encountered a problem and need to close.
We are sorry for the inconvenience.

Is there any solution for this

any permanent solution.

Check your mySql log files to see what is happening. You should have a mysqld directory with the relevant logs in it.
