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

Daniels,

I am using the latest version 1.5.1 of axis2.0, which has the above said fix. Can you please
elaborate on how I can use it with my stub. 

For instance, I am creating the stub as follows

paws = new PAWSStub(WS_ENDPOINT);

where each thread has a new instance of stub. 

Right now for threads more than 2 we are encountering the following exception

19:41:57,785  INFO HTTPSender:202 - Unable to sendViaPost to url[http://localhost:8085/axis2/services/PAWS]

    Daniels,

I am using the latest version 1.5.1 of axis2.0, which has the above said fix. Can you please
elaborate on how I can use it with my stub. 

For instance, I am creating the stub as follows with the earlier version of 1.5.0

paws = new PAWSStub(WS_ENDPOINT);

where each thread has a new instance of stub. 

Right now for threads more than 2 we are encountering the following exception

> 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.
