McAfee VirusScan Enterprise (VSE) 8.8 Patch 4

For details of VSE 8.x supported environments, see KB51111.

Zusammenfassung

The on-demand scanner (ODS), introduced in VSE 8.8 Patch 3, underwent some reconstruction in how it manages scan threads. The change was an effort to resolve a reported symptom of high memory use from the Scan32 or Scan64 process. Memory use was reported in the gigabyte ranges, which was very high. The solution implemented was to reduce the number of available scan threads. The result was that the ODS took longer to complete the same scan tasks. This deterioration of performance continues to exist in VSE 8.8 Patch 4.

Problem

On-demand scan times have markedly increased after you installed VSE 8.8 Patch 4.

Systemänderung

You installed VSE 8.8 Patch 4.

Ursache

The Patch 4 implementation takes noticeably longer to complete the same scan job because the Scan32.exe or Scan64.exe process is now using a reduced number of threads to perform the scan.

Lösung

This issue was resolved in VSE 8.8 Patch 5.

Issue resolutions in updates and major releases are cumulative; Technical Support recommends that you install the latest version. To find the most recent release for your product, visit the Product Downloads site at http://www.mcafee.com/us/downloads/downloads.aspx.
