Subject Crash when reusing svc_client with non-blocking call
Date Fri, 13 Jan 2012 20:29:21 GMT

Hi all,
       I'm performing a stress test on AXIS2C, sending multiple Asynchronous
request from a client to a service.

 I'm using an instance of svc_client to send multiple non_blocking requests
to a service, but after the request I lock the thread to wait for the
callback on complete to finish... The callback unlocks the mutex, wich
unlocks the 1st thread.

The code is similar to this:

mutex.lock();
for(i=0;i<10;i++)
{
        axis2_svc_client_send_receive_non_blocking (svc_client_, env,                    
                         
payload, callback);
         mutex.lock();
}
mutex.unlock();

   
echo_callback_on_complete(struct axis2_callback* callback,
                          const axutil_env_t*      env)
{
[does a bunch of stuff]
         mutex.unlock();
          return status;
 }

The thing is when it tries to send a second request it fails with
segmentation fault... After some debugging, I found that some of the
callback resources weren't completly deallcated when finishing 
callback_on_complete(), wich somehow makes the next send request cause a
segmentation fault...

Looking in google I found this
https://issues.apache.org/jira/browse/AXIS2C-1551, and it looks like my
issue... Somebody did fix this? is there a workaround I could use to know
when the callback resources have been released?
