Studio couldn’t be launched if one Delivery Controllers goes down

Posted 3 CommentsPosted in Citrix

A rapid post about a really strange situation I’ve encountered at a customer site. On a XenDesktop 7.5 site with 2 or more delivery controllers we have detected that if one DC goes down, the site administration via Studio or Powershell is not possible from the other Delivery Controllers. Even if I’ve encountered the problem on a XD 7.5, the problem exists in version 7.6. This is due to the status of the Delivery Controller in the site database. In […]

After a couple of dozens of minutes, the server was returning to a more expected value (about 60% of CPU usage). After this pause, the server is re-performing well and new sessions could connect without any problem. During this CPU peak period, the […]
