Last updated:
It is worth looking at receiver.exe.
Recently, I have heard more reports of unusually high CPU utilization associated with Citrix Workspace App.
Citrix has officially documented a corresponding issue:
RFWIN-41567
On Windows Server 2022, receiver.exe could cause increased CPU utilization in certain installations.
The fix has been included since Citrix Workspace App 2603.10.
On server systems, jump hosts or in double-hop scenarios in particular, this can quickly become a performance problem.
Important: I would not automatically attribute high CPU to this bug. First check:
– Which CWA process causes the load?
– Which Workspace App version is running?
– Is CPU usage persistently high or periodically spiking?
– Is a store refresh currently running?
– Are Teams/Webex/Zoom optimizations involved?
– What influence do AV/EDR/DLP have?
My recommendation:
If CWA runs on Windows Server 2022 and receiver.exe causes unusually high CPU utilization, check the version first. For builds before 2603.10, test a current supported build with a pilot group.
This is more than a community observation: Citrix has officially confirmed and fixed the issue.
