Overview

When running the GFI LanGuard Vulnerability Scan, you might encounter the following error: 

This error indicates a space or memory utilization issue on the device. This article provides the steps on how to resolve the error when GFI LanGuard Vulnerability Scan fails.

Root Cause

The error is generally related to the call to the Windows Update Agent (WUA) engine to extract the wsusscn2.cab data for the detection of Microsoft missing patches. The WUA engine fails to respond and reports the memory storage error.

Resolution

Below are five possible solutions that you can run on the GFI LanGuard server. After completing the applicable solution, run the scan to see if it resolves the issue:

1. Running the scan when the device is not in use

2. Deleting files from Windows' temporary directories

3. Optimizing memory configuration

4. Increasing the Windows pagefile virtual memory size

5. Applying Microsoft Windows KB3050265 update

Note: If the issue persists after applying these steps on the server, repeat the steps on the client machine experiencing this issue.

Solution 1: Running the Scan When Device Is Not in Use
