Our production server was crashing with "too many open files". Investigating the open files using lsof I noticed a large number of TCP connections in CLOSE_WAIT to 50.22.16.4-static.reverse.softlayer.com:https or similar. I believe the connections were being left hanging open and thus leaking.
I have added an explicit close on the InputStream and added timeouts on connect and read from the socket. This appears to have resolved the issue in our production environment.
