Based on my previous post, I want to add another bug. This time it’s a memory leak on the Citrix Monitor service that frequently happens on the XenDesktop 7.1 DDCs (it takes all available memory). The Director cannot be used when you experience the memory leak.
The issue is known and there is a private hotfix. In case you need the hotfix, request it from the Citrix Support.
Update 20.08.14: The issue still exists in XenDesktop / XenApp 7.5. There is another private hotfix for 7.5. Unfortunately it’s still not yet released.
Update 07.10.14: I just got a final hotfix for that issue. It’s still yet not released for public. In case you need it, create a Support case and refer to XD710BrokerSvcWX64002 for 64bit and XD710MonitorSvcWX86002 for 32bit.
