-----------------------------------------------------

Please look at the this thread I started regarding this issue[1].

If you service invocation happens using one thread you can switch on the keep alive as I have mentioned there. Other wise you need to stop the connection manger per each request as given below.

if you can provide a sample client code we can help you to fix the problem.

sample client code.

> My application is using axis2 web service. It  invokes web service thousand times per second. We observed thousand CLOSE_WAIT connection after the application is run for less than 10 hours.  I checked even I set REUSE_HTTP_CLIENT to false, it still gets CLOSE_WAIT.
