Memory adjustments has to be performed to be in line with the recommended and documented Memory setting for vSphere+ gateway appliance.
As per System Requirements for vSphere+ for vCenter Cloud Gateway is 28GB memory. When customers install vCenter Cloud Gateway with version less than 8.0.0.10000 (build number 20540795), memory usage shows 24GB only and will continue to use 24GB only, this mismatch can lead to problems in future.
Follow the instructions in this article to address this issue.
This issue is resolved in new release of vCenter Cloud Gateway version 8.0.0.10000 (build number 20540795). Resolution is applicable only when customer does a fresh installation of Cloud Gateway. Customers who updates to build number 20540795 from older builds will have to apply the workaround manually.
