Login fail at each A/C

[itactician]

The directadmin occurs an error.

I can't login by any AC (including the admin and clients A/C).

I am sure that the password and A/C name is 100% correct.

This error occurs times by times, and normal at every reboot the machine.

What is the serious problem?

Please check your mysql daemon and disk space.

How to check the mqsql deamon? Thank you/

 

[smtalk]

ps auxww | grep mysql, but I don't think that the problem is with MySQL.

How to solve the problem?
It occurs times by times.

Login through the shell and look at the /var/log/diradmin logfile.
