![]() Activate the Citrix Connection Quality Indicator (CQI) tool.Check the configuration of Citrix Session Reliability at the Citrix server side, as per.Maybe the issue you are encountering in your specific configuration is already a known issue which has been resolved in a certain CVAD VDA or Workspace App client version. Check the release notes, bug fixes and known issues in the CVAD VDA version and Citrix Workspace App client versions you are running in your environment.Does the CVAD environment have any other third party components which can contribute to this issue?.Which Citrix VDA servers does this issue occur in?.Which users and user groups does the issue affect?.Which network segments/zones does the issue occur in?.When does the freezing issue occur? Is there any periodic behavior or is it absolutely random?. ![]() Proper questions to ask in this direction are: Collect environment conxtextual information and by asking the right questions try to minimize the potential contributing factors. Isolate the potential root causes of the freezing incidents.There are Citrix Provisioning Services (PVS) known cases where misconfigured licensing of the PVS servers caused intermittent freezing issues. Check the licensing of all Citrix components to ensure that there is no freezing due to mislicensed components.Check TLS certificates and ensure that the certification configuration does not create any certificate warnings.There are Citrix profile configuration aspects, such as Active Writeback, which as known to cause performance issues in CVAD environments. Check the Citrix profiles (UPM) or other third party profile solution (eg.Check the Citrix EDT and DTLS protocol configuration and the MTU/MSS configuration of the various network segments of your infrastructure.Check the storage infrastructure for IOPS and performance issues.Check the core and distribution networking infrastucture for performance issues.You should search the Citrix KB for these patches depending on your version of Windows Server. There are various potential VDA software bugs which are resolved by installing corresponding fixes provided in Citrix KB patches. Ensure that all Windows Server updates and Citrix KB patches for CVAD have been deployed server-side. Check the Windows and Citrix infrastructure patching levels.Perform a configuration review of the environment and validate that there are no environment-wide misconfigurations.Perform full technical assessment of the Citrix environment (Citrix server and client components deployed).You should carry out the following troubleshooting steps in your CVAD environment: You need to perform Root Cause Analysis (RCA) of the freezing incidents. You need to identify is these events are caused by a client-side or server-side root cause. You experience random freezing incidents in your Citrix Virtual Apps and Desktops (CVAD) environment.
