Problem

When trying to start an emulator, the Charon log file reports a "Too many concurrent user sessions currently connected" message.

Solution

Steps

1. Check the number of allowed sessions for this license from the license view utility and the ones actually used from the Sentinel Admin Control Center. To do so, open your browser and open the page http://localhost:1947/_int_/sessions.html
2. Check that there is no running emulator process on the server using the license. This could be a background process.
3. Check that the license is not used by another server. This can be the case for a network license (a network license can be a red USB dongle or a Software License).
4. Check that the emulator is trying to access the correct license:
   • Define the license key id in the emulator parameters (configuration file) and/or
   • Restrict network license access by opening the Sentinel Admin Control Center and
     • unchecking the "Allow Access to Remote Licenses" and "Broadcast Search for Remote Licenses" boxes from the "Access to Remote License Managers" tab (http://localhost:1947/_int_/config_to.html)
     • setting the "Allow Access from Remote Clients" parameter to "No one" from the " Access from Remote Clients" tab (http://localhost:1947/_int_/config_from.html)

Cloned software license

In case you have several network licenses on your network (reminder: Software Licenses are by default network licenses) and you have not restricted access to remote licenses either from the Sentinel Admin Control Center or by restricting the license key ids in the configuration file, Charon will try to connect to any available license on the network. If this license is already used (another emulator running on another server), the "Too many concurrent user sessions currently connected" message can be reported. This is logical but may not reflect the cause of the error. The problem can in fact come from the unavailability of the license installed locally on the server, either because it is not accessible (USB dongle) or because the software license is in cloned state.

To solve the issue, you need to delete the software license as described here: Cloned Software License Removal, generate a new fingerprint and send us the C2V file and we will update your license.
