Hi There,

We are running a fairly large database on Redhat enterprise 7 64 bit with only MyISAM tables (I'm really trying to convince others to move to innodb). We currently have 472GB of physical memory installed. I can see that we are only using 38GB of physical memory however we are using 419GB of virtual memory. Does anyone know why that would be do we need to reduce some of our buffers? I have checked ULimits and we are not limiting memory usage.


Any help would be apricated.

Thanks, Alex.
