Not answering your question, but which exact Tomcat version are you
using? There have been a couple of code changes around those connector
classes.

Hi All,
The application we are developing has a sender which pushes indefinite
binary data to the web application hosted in Tomcat. The web application is
supposed to consumes an un-predefined limit of data per connection and
stop.
The sender is implemented using Http client and uses InputStreamEntitiy with
chunked encoding. It pushes the data to a PushServlet on the server. The
after PushServlet is done consuming data, it returns from the doPost(). But
the client keeps running because Tomcat as such does not close the stream.
Analyzing the thread dump reveals that it is stuck in cleanup where it tries
to read out the input stream. Following stacktrace talks more where exactly
it gets stuck.

Is this a bug? If not what is the right way to solve it? Is this related to
the Expect: 100 continue mechanism?
Thanks,
Santosh.
