Review Comment:
~Used 1/10th because default value of config - DirectAgentPoolSize is 500
and it was creating that many core threads from~
I've reverted this change for now. ScheduledThreadPoolExecutor is not
starting core threads at start but I was seeing most of the threads (500+500)
in waiting state
