The QueueMetrics is installed by yum
queuemetrics-java-1.6.0_22-21
queuemetrics-tomcat-5.0.28-9
queuemetrics-1.7.0.0-79

Is there is any solution to this please help  :(

Regards

Ramy Mostafa:
It's working fine now due to checking and repaire the mysql databases of queuemetrics so please follow instruction bellow as in FQ :


In order to fix these issues, you should:

stop MySQL - THIS IS EXTREMELY IMPORTANT
/etc/init.d/mysqld stop
check tables using myisamchk (use the same case as written here):
myisamchk -c /var/lib/mysql/queuemetrics/*.MYI
if any error is shown, repair tables:
myisamchk -r /var/lib/mysql/queuemetrics/*.MYI
after that, restart Mysql:
/etc/init.d/mysqld start

:)
Regards
