ACTUAL BEHAVIOR
---------------
MWM: scheduler takes too long to stabilize
While testing MWM 2.2, a specific scheduler (SCHED1), which handles 10K tasks and is not the biggest scheduler, takes too long to startup and stabilize. It can take as long as 1 hout for the scheduler to become 'green' in Batch Control Global View and after 90 minutes of execution, 'update schedule' entries are still not logged in the stdout log.
Other schedulers in the environment are taking 30 minutes for stabilizing.
