Technical Note: [Accelops KB] Installation: Virtual LInux Swap Memory is Increasing

I noticed that swap memory usage in my virtual linux machine keeps growing though I still have plenty of free physical memory, what should I do?

The problem could be that you have allocated memory in all virtual machines in your ESXi server higher than the physical memory in your ESXi server. You may need to shutdown one virtual machine or reduce the memory in each virtual machine to make sure that your actual physical memory is not exceeded.
