   The issue involves several areas of configuration, plus having a JMS broker that continually fails on Put requests. The parameters are the GC interval for the NiFi JVM, the max number of open sockets for your OS, and a Put rate that is high enough to exceed the max number of open sockets within the GC interval. How one puts this all together is beyond me. However, I've provided a detailed explanation of the problem in the ticket and examination of the code, with the understanding that the connections are cached, reveals the existence of a resource leak. 
   While there may be better ways to deal with the cached connections, given the API I have to work with what I've offered is my best effort to deal with the problem.
