In the past few days, we've been getting an error when we open an application in the Parallels 2X client. It says Code [01/00000005] Maximum number of sessions reached. The Parallels knowledgebase says I should increase the number of sessions in Agent Settings tab of VDI Host Properties, but we don't have a VDI listed in our VDI tab as we're not using that config. On the RD Session Hosts there is the same tab, but the setting is inherited and the max sessions is 250. We're usually operating at about 5-10 sessions at a time. Whats really odd about the error is that it appears to clear itself, if I double click the shortcut for an app in the client window, the error may appear again. But if I keep trying to open the app, the error stops eventually and allows me access. Any ideas whats causing this and how to fix it please?
