The first thing I would do is make sure that the payload is being sent without any spaces/newlines, i.e.:
<ns1:setInterface xmlns:ns1="http://localhost:9090/axis2/quagga_openapi";><name>eth0</name> <address>192.168.0.1</address></ns1:setInterface> In my (not vast) experiences with Axis2/C, it seems to have trouble handling "human formatted" XML.
