Error: Insufficient system resources exist to complete the requested service. : Event ID 802, 1296 and 1306

Question

Hi

In https://social.technet.microsoft.com/forums/windows/en-US/803f2635-a23b-4370-8974-7087351498a6/how-to-disable-rd-connection-broker-load-balancing?forum=winserverTS it is mentioned to set up a GPO with Use RD Connection Broker load balancing set to Disabled (found under Computer Configuration\Policies\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\RD Connection Broker).

For my setup, I need this. So I have 1 machine with the connection broker role and 2 machines with the session host role. This GPO is linked (and now active) to the RDSH (RD Session Host) servers. I have no issue launching any of my applications in my RD collection so all seems to work fine.

But with this GPO, is it expected to have: "Error: Insufficient system resources exist to complete the requested service" error events? On RDCB: Event ID 802 and on RDSH: Event ID 1296 and 1306 (all events listed below are from the same timestamp)

RDSH: Microsoft-Windows-TerminalServices-SessionBroker-Client/Operational

#Error event 1306
Remote Desktop Connection Broker Client failed to redirect the user 
MYDOMAIN\my_user.
Error: Insufficient system resources exist to complete the requested service. 

#Error event 1296
Remote Desktop Connection Broker Client failed while getting redirection packet from Connection Broker.
User : MYDOMAIN\my_user
Error: Insufficient system resources exist to complete the requested service. 

#Verbose event 1301
Remote Desktop Connection Broker Client received request for redirection. 
User : MYDOMAIN\my_user 
RDP Client Version : 5

RDCB: Microsoft-Windows-TerminalServices-SessionBroker/Admin

#Error event 802
RD Connection Broker failed to process the connection request for user MYDOMAIN\my_user. 
Error: Insufficient system resources exist to complete the requested service. 

It is not really clear to me what "system resources" "exist" that are "insufficient" or where to find out...

Best regards,
