Maximum Number of Sessions

For yuuvis® RAD, the maximum number of sessions per user is set to 1000 by default.

If this number is exceeded, the user will see an error message.

The number can be changed via yuuvis® RAD management-studio:

Main menu > System > Settings > Core service > Cluster > Session services

The limitation of the maximum number of sessions serves as protection against excessive resource consumption. A web user / end user can never reach the default value of 1000 simultaneous sessions.

However, automated tools / API users can achieve this value if a new session is created per call or with just a few calls and this session is not closed. If these tools are used frequently, the permitted sessions can be used up.

As a workaround, you can increase the number of allowed sessions in yuuvis® RAD management-studio or set it to -1 to allow an unlimited number of sessions.

To solve the problem in the long term, however, it is recommended to adapt automated tools so that either a single session is used or the sessions used are also closed again.
