If the quarantine is working properly, from the moment you delete an account, that license will be locked for 24 hours until it is actually available to be allocated to another user.
I'd say it is a license control. Otherwise, it would be possible to realocate a license many times during the day and it would not be exactly a named user.
If the problem persists after the 24 hour period, then it is not working as expected and you should report this as a bug.
Hope this helps,
I agree with Erich Schiino.
I would also recommend to check and delete all the ".shared", ".pgo" and ".meta" files since those are the files used to maintain user license details. Just don't forget to keep the backup of those files.
After that, you can restart the QV Server Service to take affect the changes you have made.
Hope this helps.
I want to post that deleting the PGO files can lead to big issues. You are correct this is the place where the licensing information is stored. However, if you have a large number of User Cals assigned this will delete all of the cals and you will have to reenter them. This can be time consuming. .To delete an assigned user, thus freeing a Document CAL, click on theDelete button . If the CALhas not been in use for the last 24 hours, it will be deleted immediately. If the CAL is currently being usedor has recently been used, it will be marked for deletion, and not allow new sessions for user accessthrough this CAL, but will still occupy an allocated CAL until the Quarantine time ends. During thisperiod, you may undelete by clicking theRestore button . After the quarantine period, you maydelete the entry manually (by clicking on theDelete button), or restart the QVS service.
