Windows

Increase non-interactive desktop heap on NetVault Server: On Windows-based NetVault Servers, the default setting for the non-interactive desktop heap memory setting has the potential to be exhausted when you do the following:

•
Run several simultaneous jobs on the NetVault Server.
For example, when you run 25 simultaneous jobs, NetVault uses about 200KB additional non-interactive desktop heap. In this scenario, some jobs continue to run, while others fail with the message “Job Died Unexpectedly.” This issue is a known Windows problem (ID: 184802).
•
Add several drives to a Virtual Tape Library (VTL).
•
Browse a Backup Selection Set containing a deeply nested directory structure. In this scenario, the message “failed to get connection to plugin” is displayed.

To correct these issues, increase the size of the non-interactive desktop heap in the following registry value:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SessionManager\SubSystems\
Windows
* 
NOTE: This key is not available in Windows Server 2019 and Windows Server 2022.

The SharedSection setting in this registry value controls how the desktop heap is allocated. The heap size is specified in KB. The format for specifying the heap size is as follows:

SharedSection=xxxx,yyyy,zzzz
xxx defines the maximum size of the system-wide heap
yyyy defines the size of each desktop heap
zzzz defines the size of the desktop heap that is associated with a non-interactive Windows station
To increase the size of the non-interactive desktop heap:
1
Start the Registry Editor. (In the Run box on the Start Menu, type regedit, and press Enter.)
2
Expand the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\SubSystems key.
3
On the right pane, right-click Windows, and select Modify.
4
In the Edit String dialog box, change the value for the SharedSection parameter from 512 to 1024:
Windows SharedSection=1024,3072,1024
5
Click OK, and close the Registry Editor.
