McAfee DAT files
Resources such as disk space and available memory are essential for a successful update. McAfee has discovered that updates are failing due to insufficient available resources even though the systems meet the original system requirements. This has been confirmed in customer environments as well as in McAfee internal testing.
Increases in DAT file sizes
The original minimum requirements to use VSE can become outdated because of changes and developments in the field necessary to deal with malware. Over time, DAT signature files have increased considerably in size and can continue to increase because of the ever-evolving malware threats in the field. Therefore, a tipping point of resource availability and resources required to complete an update might be reached. This tipping point can vary from one environment to the next and can be influenced by the tasks or workload of the specific node.
As of March 2012, the latest revised minimum and recommended system requirements for VSE are:
|Pentium class processor
Pentium IV class processor or higher
1 GB or more
|NOTE: Low memory will result in updates taking longer to complete.|
|1 GB or more free space|
|NOTE: Insufficient disk space will stop VSE working as expected.|
