We are seeing thread leaks when having client open connections to a web server that hangs. Has any one seen this happening?? How do we ensure that the library correctly closes socket connections on failures, cleaning up system resources, and threads actually finish in the timeout period and get freed up. Would using MultiThreadedHttpConnectionManager be of any help??
Below is the trace.

Any pointers or suggestions in this regard will be very helpful. Thank you all for your help and support.
