I would like you to fix the following issues.
The user console session is disconnected by stop other IM service in a redundant configuration.
1. Log in to the user console (https) of node 2.
2. Enter data until just before submitting any Task. For example,"Create User".
3. Stop IM service of node 1 with "stop_im"
4. Click Submit in the user console of node 2.
5. Force return to the sign-in screen. displayed "Error: User's session has expired"
It happens once every few times.
