Hi All,

Can someone help me to know what could be the possible reason for HIGH SWAP
on MySQL Server ??

Environment is below given :

OS - CentOS 6.4

Database - MySQL 5.5

Application which is using the DB : Roxen CMS


Please suggest me while I am taking a look on TOP, I see mysql is the
process which is causing 100 % Memory and SWAP

How can i do the low level analysis ?


Please help me.

Thanks
Vimal
