Description
The Citrix Workspace Environment Management Agent fails to connect to the Norskale Infrastructure Service, and the Citrix WEM Agent Service log contains the following error:
ConfigurationDataSourcesHelper.CheckAgentBrokerServiceClient() : System.ServiceModel.ServerTooBusyException : Server 'net.tcp://[brokername]:[port]/AgentBrokerSvc/service' sent back a fault indicating it is too busy to process the request. Please retry later. Please see the inner exception for fault details
Resolution
#1: Stop the Norskale Infrastructure Service on the WEM Broker server
#2: Locate the "Norskale Broker Service.exe.config" configuration file in the broker installation directory (by default , it is here: C:\Program Files (x86)\Norskale\Norskale Infrastructure Services") and create a backup copy of this file.
#3: Open the original config file with a text editor as Administrator, locate the following two lines:
<serviceBehaviors>
<behavior name="">
Add the following line immediately below the <behavior name=""> tag:
<serviceThrottling maxConcurrentCalls="2000" maxConcurrentSessions="2000" maxConcurrentInstances="2000"/>
#4: Save these changes, then restart the Citrix WEM Broker Service.
Problem Cause
This error occurs when the broker's hardware specifications are insufficient to allow it to open enough concurrent threads to serve every request made by incoming agent service connections.
