Environment
Spirent TestCenter
Explanation/Resolution
In large scale test, getting all the session info at the same time may cause STC unstable.
In summary, this issue is a general performance issue for STC, not a specific functional bug. We suggest customer to use "Get session info per page" when doing large scale testing.
Root Cause
The memory is used up when getting all the session information at the same time
