Hello,
We have 4000 db and 4000 user (more or less) in MySQL, each db has one user
assigned.
Some times, this is happened more often, show the next error:
ERROR: 1045 'Access denied for user: ‘username@host’ (using password:
YES).
So we kill/restart the mysqld process … after that the user is able to login.
We have the next escenario.
HP-UX 11.00
MySQL 3.23.30 gamma-log
512 RAM.
My.cnf (for large systems)
# The following options will be passed to all MySQL clients

port = 3306
socket = /tmp/mysql.sock
# Here follows entries for some specific programs
# The MySQL server
[mysqld]
port = 3306
socket = /tmp/mysql.sock
