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.
