Environment

McAfee VirusScan Enterprise (VSE) 8.x

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

Problem

When a client tries to access network shares, either of the following error is displayed:

Not enough server storage is available to process this command

Not enough memory to complete transaction. Close some applications and retry

Problem

You see the following entry in the Windows System Event log:

Event ID : 2011
Source : Srv
Description: The Server's configuration parameter "IRPStackSize" is too small for the server to use a local device. Please increase the value of this parameter.

Problem

These errors might be reported on some computers after you apply a VirusScan Patch.

Cause

On some computers, you might see this error after you install a VirusScan Enterprise Patch that updates the drivers.
You see this issue on some low specification computers where the available CPU or RAM is insufficient for the VirusScan FEAD optimizer to run. VirusScan FEAD is a high-compression tool used before VSE 8.7i.

Solution

If you see this issue after you apply a VSE Patch (updating the VirusScan drivers), restart your computer.

In all other cases, use the solution below.

Solution

CAUTION: This article contains information about opening or modifying the registry.

The following information is intended for System Administrators. Registry modifications are irreversible and could cause system failure if done incorrectly.
Before proceeding, Technical Support strongly recommends that you back up your registry and understand the restore process. For more information, see: http://support.microsoft.com/kb/256986.
Do not run a REG file that is not confirmed to be a genuine registry import file.

Increase the IRPStackSize value in the registry

Click Start, Run, type regedit and click OK. Then, locate the following key:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\parameters]
In the right pane, locate the IRPStackSize key.
If the IRPStackSize value does not exist:
1. In the Parameters folder, right-click in a blank area of the right pane and select New.
2. From the menu, select DWORD Value and change the default name to IRPStackSize and press ENTER.
  
  NOTE: The IRPStackSize name is case sensitive.
Double-click the IRPStackSize key.
In the Base section, select decimal, and in the Value data field, type a value that is larger than the value listed, then click OK.

NOTE: McAfee recommends that you increase the value by 3. Example: If the previous value was 11, type 14. The default value is 15.
Exit the registry editor and restart your computer.

NOTE: If the issue persists, increase the value of IRPStackSize in further increments of 3.

Operating System IRPStackSize values

Windows XP, Windows 2000, Windows Server 2003 Default value is 15.
