This has happened to us twice in the past few months:
Users try to login and after entering their login info it sits and spins and GE does not open. Eventually it will pop up an error that says it loaded incorrectly and then users will start getting the pop up about no license being available.
When we go in to SQL to clean up logins we see all of the hung up sessions with "NULL" beside them. Once we get those cleaned up users are able to log in again as usual.
We don't see any reported event in the log that would have caused this.
Any ideas what could cause this to happen? This time it happened at the beginning of our day but last time it was in the middle of the afternoon......
GE's suggestion was to replace the startup link to a batch file to kill old sessions. We did that a few years ago and haven't had any license issues since then. Any crashes will leave a license in use.
We have seen this too since we went to CPS12. In working with GE Support, it is believed that all of ours are caused by 2 things; Fatal errors kicking users our of Centricity and users who click on the X in the Application Window upper right corner instead of clicking on the "Log Out" button that looks like exiting a door. Every time either of these occur it creates an orphaned session in table iLicUserInfo. The GE cleanup logins process is supposed to cleanup this table, but it is also dependent on your User Idle settings. We have bumped our Idle settings to an hour because we have Dental Providers who do not want to have to log back in to Centricity in the middle of a procedure because they haven't touched the chart in 30 minutes. What this means is that the cleanup logins process won't even attempt to touch these orphaned sessions until they have been idle for at least an hour old.
It is possible that this is not strictly a CPS12 issue. We cannot say for sure, because we bumped up our Idle timeout to an hour around the same time we went to CPS12, so it is possible that the cleanup process was keeping up with the orphans when we had it set to 30 minutes.
