Environment
Security Expert Client
Cause
The Concurrent client connections are being used up by active Security Expert clients or clients that have not been properly logged out.
Available licenses can be confirmed by checking under About | License. The Concurrent client connections feature will show the number of used connections out of the total available for use.
Resolution
1 - Log out unused Security Expert clients.
- Currently logged in Operators can be determined by checking the Windows application event logs Security Expert Data Service events for "New Operator Logon" and "Remove Operator by Disconnect". These contain the record id and name of the operator identifying who has logged in. Those Operators are still logged in if there is no reciprocal disconnect message seen.
- If it can't be determined from the Operator which machine is being logged into this can be identified by viewing currently open ports to the server using Wireshark.
2 - Correctly close the Security Expert client to release the client license
- Closing the Security Expert client by clicking the "x" on the windows taskbar will close the application without first logging out the current Operator. This can result in the concurrent client license not being released. To then release the consumed licenses the Security Expert server must be restarted.
Taskbar
- Log out the Operator before closing the Security Expert client or close the Security Expert client by clicking the "x" at the top right of the client window.
Close Client
3 - Operator timeout
- This setting is disabled by default. Set the "Enable operator timeout" setting on Operators for an appropriate time. After this amount of time with no activity the Operator will be automatically logged out releasing the client license.
