Hi David,
I would like to know why I can test the basic scenarios with only 2 users. I
think that it would be a good idea create a kind of label to control the
number of users. I have always the same error because my pool is empty... I
found another question in the mailing list about this issue. I don't
understant why I can't test the scenarios with a limit number of users. Why
is mandatory have thousands of users? It may people want to check its IMS
core with a bit users before.
I need to know if It is imposible run basic scenarios for only 2 users. I
prefer know it instead of change the manager.xml for nothing.
Thanks a lot for your assistance.
