Hi Chad, The default max connections per host is 2 in httpclient, so that's almost certainly what you're running into (connection pool is too small). In this scenario you will want to increase both the max total connections and the max connections per route.
See http://hc.apache.org/httpcomponents-client-ga/tutorial/html/connmgmt.html#d 4e638 for examples. Jon ........
