We are currently on release 4.0.6 Linux 64 bit.
We have a user that is setup with a connection limit for the maximum number of sessions per user account set to 5. This user is not currently logged into the application. They receive the message "too many users logged onto this account" when they attempt to login. If we set the connection limit for this user to 6 sessions they are able to login.
This also happens occasionally for other users. They are not able to login unless we increase their connection limit. System does not seem to reset when certain users are no longer active.
