Issue/Introduction
Error Message : N/A
When performing several DB Loads in a row the User Interface / AWI becomes unresponsive.
Here is what happens in the background :
1 - The PWP looks in the ITL (internal task list table), then triggers the WPs with gen-ox via the db tables.
2 - DB Load writes an ITL - re - us - ca (refresh user cache) message at the end of the process : the cache for the FOLDERTREE (OFS) is invalidated at this point.
3 - Every WP sends a kick-ofs "please get a new tree, the old is no longer valid" for every registered user. So the number of OFS messages = number of WPs x number of connected users.
The issue is particularly visible in systems with many WPs and users.
Cause
Cause type: Defect Root Cause: For every transport case every WP triggers a folder-cache refresh for all users. This normally has to be done by the primary work process only.
