Subject Newbie to axis2c - 1.6.0 core dump
Date Tue, 26 Mar 2013 17:55:50 GMT
Background:
==========
I'm an experienced programmer, but new to axis2c.  I initially downloaded axis2c 1.7.0 and
got that working but it is intermittent, seems to not work it there is a gap between synchronous
messages.
I tried an async keepalive every 25 seconds, which seemed to help a bit, but not enough. 
I then looked around and realized that 1.7.0 is "unstable", so sought out the stable release
1.6.0 and installed that.  I now just change a link so can test with either.

Problem:
=======
Async messages using axis2_svc_client_send_robust() work.  sync messages using axis2_svc_client_send_receive()
core dump in the axis2c code.  This is code that works (intermittently) with 1.7.0.  I've
played with this for a while, trying xml2 instead of guththila and that core dumps as well.
  I've looked though the examples that come with axis2c 1.6.0 code ,and think I'm doing it
right?
Any ideas?  I'm willing to send my code if needed.  The basic premise for my app (which there
is no example of), is that I do the init once, for the one endpoint,  for both sync or async
operations, and then wait for async and sync requests, and then set up the request for that
operation using either robust_send or send_receive.
