The site went over the number of licenses about 9 days ago which triggered the Supplemental Grace Period.
According to the Citrix Documentation: https://docs.citrix.com/en-us/licensing/11-14/technical-overview.html
“If all licenses are in use, the supplemental grace period enables users to connect to a product for a limited period of time allowing you to address the issue. The default supplemental grace period is 15 days. During this period there is no limit on connections. After it expires, normal (to the extent of license availability) connection limits are enforced. Users are not disconnected, but as they disconnect, no new connections occur until license levels return to normal. Supplemental grace periods are granted per product and edition and per Subscription Advantage Eligibility date (per product) and only for Retail licenses. For example, if you have two clients requesting XenDesktop Enterprise Concurrent, with different Subscription Advantage Eligibility dates, two supplemental grace periods are granted. Rearming the supplemental grace period – When you take corrective action (for example, installing an additional Retail license), the supplemental grace period is rearmed, and normal license limits are enforced again. If you take action while the supplemental grace period is in force, the License Server exits the supplemental grace period before rearming. When the supplemental grace period is rearmed, you can trigger a new 15 day supplemental grace period the next time you go over the license limit.”
So this behavior is normal and the only way to turn this off would be to follow –
1) Go To:C:Program Files (x86)CitrixLicensingMyFiles
2) Open the file: “CITRIX.opt” with Notepad.
3) At the bottom of that file, add
5) Restart all Citrix Services (or Reboot)
to remove supplemental all together or to add new license files.
It is worth noting that the Supplemental Grace Period is normal when a user goes over the allotted number of Citrix license. It is also normal for the error to show up in Director even after no SGP licenses are being used. The SGP is a one time grace period that last 15 days. After this there can be no more SGP licenses applied to uses but normal ICA licensing will occur. The idea is that you have 15 days to correct the issue before the SGP and only the SGP licenses expire. The only way to rearm is to buy more.
