It seems that CWP and the XML gateway are having issues releasing memory after a query has been made. I'm POSTing 3-5 MB of text data, and with each post I can see the memory usage jump up in the activity monitor on Windows Server 2012 R2. There's a very clear step-up of memory usage with each post, and the memory usage never decreases until the WPE has been turned off. Memory usage goes back to normal when it starts up again.
Any suggestions on improving this? The RAM gets used up pretty quickly, and having to manually stop and start it over and over again isn't feasible.
