Hi, I am using zabbix (monitoring software) with mysql. zabbix goes
zombie and complains with messages suggesting that Database cache
perhaps is corrupted. How can I check and fix it? I am using Centos
5.1, cpu Intel(R) Xeon(R) CPU and 1 Gb of RAM.


my.cnf is as follows:

[client]
port = 3306
socket = /var/lib/mysql/mysql.sock
[mysqld]
port = 3306
