arcserve-KB : ARCFlashVolDrv.Sys Driver utilizes more Non-Paged Pool Memory.

Last Update: 2016-11-23 17:16:38 UTC

Description:

ARCFlashVolDrv.Sys Driver utilizes more Non-Paged Pool Memory. In Windows 2003 (x86) Operating System this could be a problem due to the memory limitation. 

The probable reason could be,

There are lots of VSS snapshots in the machine, the driver attaches to the snapshots even when they were created by other application.  Driver attaches to the snapshots to monitor the changes happening on the snapshots; if the changes to the snapshots are not monitored it will result in a corrupted backup.

Solution:

-Check if there are any existing shadow copies. Run the command “vssadmin list shadows”. It displays all the existing list of shadow copies for all the volumes on the computer. If the shadow copies are present, follow the steps mentioned below to delete them and disable Shadow Copies on volumes.

Solution 1

Note:- Following the steps mentioned below would delete all the existing VSS shadow copies. If you are concerned about deleting all the existing shadow copies, go to Solution 2.

a. Run the following command to delete all existing shadows copies:
     vssadmin delete shadows /all
     Type Y or N to delete the shadow copies or not. To proceed with deleting the shadow copies, type Y.

 b. Disable the built-in windows shadow copy. Goto My Computer, Right click on C:\ Drive => Select Properties => Select Shadow Copies tab  =>  
     Select C:\ Volume and click Disable.
 c. Repeat step b on all volumes.

Solution 2

 a. Goto My Computer, Right click on C:\ Drive => Select Properties => Select Shadow Copies tab => Select C:\ Volume and delete some of the oldest shadow copies.
b. Repeat step a for all the volumes.
If the ARCFlashVolDrv.Sys still utilizes more Non-Paged Pool Memory, then follow Solution 1.
