How to Increase VmallocTotal

["Bill Snapko" <bsnapko@xxxxxxx>]

Hello,

 

I am using a RedHat Enterprise WS v4 distribution.

 

I am looking to increase the value that is displayed by VmallocTotal using `cat /proc/meminfo`. The value I currently have is "VmallocTotal:   106488 kB". This is unacceptable for the current situation.

 

On another system using a Fedora Core 3 distribution, the VmallocTotal value is "VmallocTotal:  3612664 kB". This is what I want.

 

Both systems have 1GB RAM installed. The hardware is identical. The distributions are the difference.

 

I have attempted to follow the definition of VMALLOC_START to ascertain if I could adjust it to get the VmallocTotal to the value I want. I have been unsuccessful down this path.

 

I am looking for a system utility or something to configure to allow the RHEL 4 system to increase its vmalloc space. I would prefer not to have to recompile the kernel for this to work.

 

 

Thank you for your help.

 

Bill
