Name: PK36293
=============
 
Summary:
   Memory leak under load with same user ID
 
Problem Description:
   When portal is put under load by using the same authenticated user ID, a memory leak can occur. Note that performing load tests for authenticated users with the same user ID (concurrent use of portal with that user ID) is not a supported scenario. Load tests need to ensure that a user ID is only logged in once.
   
 
Problem Solution:
   A synchronization gap in the event broker implementation was closed. The gap caused deregistration of listeners to not take effects, thus still referencing the listeners which then lead to the leak.
