Hi all,
Now I'm facing a big problem and see if anyone know how to solve it. I'm
using RS6000 AIX 4.3.2 CPU*2 1G RAM with HA. And DB is MySQL 4.0.12-max.
Here is the content of my.cnf.
[client]
#password = your_password
port= 3306
socket = /tmp/mysql.sock
# Here follows entries for some specific programs
# The MySQL server
[mysqld]

socket = /tmp/mysql.sock

Now I have to restart mysqld one time in every day, because of cannot
connect it. The error message in .err file is:
