That's exactly the case in my situation. Thank you both!! -----Original Message----- From: Sam Crawford [mailto:[email protected]] Sent: Friday, July 22, 2011 5:55 AM To: HttpClient User Discussion Subject: Re: ConnectionPoolTimeoutException
My experience leads me to agree with Oleg. I would suggest adding logging for connection management (see http://hc.apache.org/httpcomponents-client-ga/logging.html). Make sure you're always consuming the content when handling responses. When I first began working with HttpClient I was aborting our response handling process if I saw a non-2xx/3xx response code *without* consuming the response - this led to the connection not being evicted.
